Description

  The present invention relates to an electro-optical device and an electronic apparatus suitable for use in displaying various types of information.

  Conventionally, various electro-optical devices such as a liquid crystal device, an organic electroluminescence display device, a plasma display device, and a field emission display device are known. As an example of such an electro-optical device, a multi-matrix liquid crystal device in which liquid crystal is sealed between a substrate having data lines and a counter substrate having scanning lines is known.

  In this method, the number of data lines (signal lines) corresponding to one scanning line is doubled (double matrix), tripled (triple matrix),..., N (N-duplex matrix: N is 2 or more) This is a technique that multiplexes the number of times of the drive voltage to each pixel by N times. Thereby, since the period for displaying each pixel can be increased N times, there is an advantage that the brightness and contrast ratio of the screen can be improved. Also, when the multiplex matrix method is adopted, the duty ratio can be lowered as compared with the case where the simple matrix method is adopted, so that the drive voltage can be reduced and the drive frequency can be reduced, thereby realizing low power consumption. It also has the advantage of being able to.

  As an example of such a multiple matrix system, an example of a liquid crystal device to which a double matrix system is applied is described in Patent Document 1. In the liquid crystal device according to Patent Document 1, the width of each scanning electrode (scanning line) is set to the length of two pixel electrodes arranged in the Y direction (vertical direction), and each scanning electrode is imaged. Wiring is alternately arranged from both sides of the display area toward the inside thereof. As a result, the frame regions located on both sides of the image display region need only be provided with half of the second routing wiring, so that the frame regions on both sides in the X direction can be narrowed in a balanced manner.

  In the above-described double matrix liquid crystal device, a parasitic capacitance is formed between pixel electrodes adjacent to each other in the vertical direction (data line extending direction). That is, the pixel electrodes adjacent to each other in the vertical direction are capacitively coupled by the parasitic capacitance existing therebetween. For this reason, in such a liquid crystal device, when a method of inverting the voltage polarity for each scanning electrode, that is, for each line (generally referred to as “one-line inversion driving method”), stripes are caused by the influence of the parasitic capacitance. There is a problem that a pattern-like display defect occurs.

  The cause of such display failure will be briefly described.

  In the above double matrix type liquid crystal device, the width of the scanning electrode is set to the length of two pixel electrodes arranged in the vertical direction. For this reason, when the one-line inversion driving method is applied to such a liquid crystal device, the voltage polarity is inverted for each pixel electrode corresponding to two rows. That is, the pixel electrodes for two rows arranged opposite to any one scan electrode have a potential corresponding to positive or negative polarity, and accordingly, the upper and lower sides of any one scan electrode. The pixel electrodes for two rows arranged opposite to the other scanning electrodes adjacent to the electrode have a potential corresponding to negative or positive polarity.

  Further, as described above, since parasitic capacitance exists between pixel electrodes adjacent in the vertical direction, the potential from the pixel electrode adjacent in the vertical direction goes around each pixel electrode via the parasitic capacitance. become. Here, when the potential of any one pixel electrode row and the potentials of other pixel electrode rows adjacent in the vertical direction have the same magnitude and the polarity is inverted, the potentials of the two are canceled out. The arbitrary one pixel electrode row is not affected by the parasitic capacitance. For this reason, the effective value of the liquid crystal corresponding to the arbitrary one pixel electrode row does not fluctuate. However, if this is not the case, the potential of the same polarity from another pixel electrode row adjacent in the vertical direction is applied to the arbitrary one pixel electrode row through the parasitic capacitance, so that an extra charge is added. . For this reason, the effective value of the liquid crystal corresponding to the arbitrary one pixel electrode row fluctuates.

  As a result, any one pixel electrode row that is not affected by the parasitic capacitance and any one pixel electrode row on which an extra charge is added due to the influence of the parasitic capacitance are alternately generated. Since such a phenomenon occurs over all pixel electrode rows, striped display defects occur due to such imbalance.

  The present invention has been made in view of the above points, and a double matrix type electro-optical device capable of preventing the occurrence of a striped display defect by devising the shape of a scanning line. Another object is to provide an electronic device.

  In one aspect of the present invention, an electro-optical device includes a plurality of pixel electrodes arranged in the row and column directions and a plurality of pixel electrodes provided on both sides so as to correspond to the plurality of pixel electrodes arranged in the column direction. A plurality of scanning lines intersecting with the plurality of data lines, a plurality of switching elements provided corresponding to intersections of the plurality of data lines and the plurality of scanning lines, and connected to the pixel electrode; A scanning line driving circuit that sequentially scans the plurality of scanning lines, and each of the scanning lines is provided corresponding to each row of the pixel electrodes, and skips one scanning line. Connected every two rows, and the scanning line driving circuits are arranged so as to alternately mesh in the direction of sequentially scanning the scanning lines.

  The electro-optical device includes a plurality of pixel electrodes arranged in the row and column directions, a plurality of data lines provided on both sides so as to correspond to the plurality of pixel electrodes arranged in the column direction, and a plurality of data A plurality of scanning elements intersecting the line, a plurality of switching elements such as TFD elements or TFT elements provided corresponding to the intersections of the plurality of data lines and the plurality of scanning lines, and connected to the pixel electrode; And a scanning line driving circuit that sequentially scans the scanning lines. In a preferred example, the scanning line driving circuit sequentially and exclusively selects one of the plurality of scanning lines, and selects the selected scanning line immediately before the selected scanning line. A scanning signal corresponding to the inverted potential of the scanning line and the polarity can be supplied (one-line inversion driving method). Note that when a TFT element is applied as the switching element, the plurality of scanning lines correspond to the plurality of gate lines, and the plurality of data lines correspond to the source lines.

  In particular, in this electro-optical device, each of the scanning lines is provided corresponding to each row of pixel electrodes, and the scanning lines are skipped by one row and connected every two rows, and scanning line driving is performed. The circuits are arranged so as to alternately mesh in the direction in which the scanning lines are sequentially scanned. In a preferred example, each of the scanning lines extends in a direction substantially orthogonal to the extending direction of the data line, and is arranged so as to alternately mesh with the extending direction of the data line.

  For this reason, by sequentially scanning the scanning lines based on the one-line inversion driving method, the pixel electrodes corresponding to two rows can be driven simultaneously, and the voltage polarity of the pixel electrodes can be changed for each row of pixel electrodes. Can be reversed. Here, when attention is paid to any one pixel electrode to which a potential corresponding to positive or negative polarity is applied, the other pixel electrodes adjacent to the upper side and the lower side of the arbitrary one pixel electrode are accordingly changed. A potential corresponding to negative or positive polarity is applied. Further, a parasitic capacitance is formed between the arbitrary one pixel electrode and the other pixel electrode adjacent thereto.

  For this reason, the potential corresponding to the negative or positive polarity of the other pixel electrode adjacent to the upper and lower sides of the one pixel electrode side to which the potential corresponding to the positive or negative polarity is applied passes through the parasitic capacitance. On the other hand, on the other pixel electrode side to which the potential corresponding to the negative or positive polarity is applied, the potential corresponding to the positive or negative polarity of the one pixel electrode circulates through the parasitic capacitance. Here, since these potentials have the same magnitude and opposite polarity, the potentials cancel each other. As a result, the one pixel electrode is not affected by the parasitic capacitance, so that the effective value of the liquid crystal corresponding to the one pixel electrode can be suppressed from fluctuating. Such an action occurs over the entire pixel electrode. Thereby, it is possible to prevent a striped display defect from occurring.

  In a preferred example, the plurality of scanning lines can be formed in a U-shape. In a preferred example, each of the scanning lines has a first portion, a second portion, and a third portion, and the first portion and the third portion are spaced corresponding to one row of the pixel electrodes. The second portion connects one end side of the first portion and one end side of the third portion. The pixel electrodes corresponding to one row are opposed to each other.

  One aspect of the electro-optical device includes a scanning line driving circuit that sequentially scans a plurality of scanning lines, an element substrate having wiring connected to the scanning line driving circuit, and a counter substrate, and the element substrate; A frame-shaped seal member formed by dispersing and arranging a plurality of metal particles is provided between the counter substrates, and the second portion is disposed at a position corresponding to the frame-shaped seal member; The wiring is vertically connected to the wiring via the plurality of metal particles. Accordingly, the scanning line driving circuit and the scanning line are electrically connected via the plurality of metal particles mixed in the frame-shaped sealing member and the wiring (leading wiring). That is, the scan driving circuit can supply a scan signal to the scan line.

  In a preferred example, when N is a natural number, a data line located on the left side of the pixel electrode among a set of data lines provided on both sides of the pixel electrode is connected via the plurality of switching elements. , (4N-3) rows and (4N-2) rows are electrically connected to the plurality of pixel electrodes, and a data line located on the right side of the pixel electrodes includes the plurality of switching elements. And electrically connected to the plurality of pixel electrodes corresponding to the (4N-1) and 4n rows.

  In addition, an electronic apparatus including the electro-optical device as a display unit can be configured.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In the following embodiments, the present invention is applied to a liquid crystal display device as an example of an electro-optical device. In the present embodiment, in a double matrix type liquid crystal display device, a stripe-shaped display defect is prevented from occurring by devising the shape of the scanning line.

[Configuration of liquid crystal display device]
First, the configuration of the liquid crystal display device according to the first embodiment of the present invention will be described. FIG. 1 is a plan view schematically showing a schematic configuration of a liquid crystal display device 100 of the present invention. In FIG. 1, the configuration of electrodes and wirings of the liquid crystal display device 100 is mainly shown as a plan view. Here, the liquid crystal display device 100 of the present invention is an active matrix driving type liquid crystal display device using a TFD element and a so-called double matrix type liquid crystal display device. The liquid crystal display device 100 is also a transmissive liquid crystal display device using an illumination device such as a backlight.

  First, a cross-sectional configuration of the liquid crystal display device 100 will be described with reference to FIG. Thereafter, the configuration of the electrodes and wirings of the element substrate 91 will be described. FIG. 2 is a schematic cross-sectional view taken along a cutting line A-A ′ passing through one row of pixel electrode groups in the liquid crystal display device 100 of FIG. 1.

  In FIG. 2, the liquid crystal display device 100 includes an element substrate 91 and a color filter substrate 92 disposed so as to face the element substrate 91 bonded via a frame-shaped seal member 3, and liquid crystal is enclosed therein. Thus, the liquid crystal layer 4 is formed. The frame-shaped seal member 3 is mixed with a conductive member 7 such as a plurality of metal particles. In the liquid crystal display device 100, a spacer (not shown) is disposed between the element substrate 91 and the color filter substrate 92, and the two substrates are defined at a constant interval by the spacer.

  On the inner surface of the lower substrate 1, pixel electrodes 10 made of a transparent conductive material such as ITO (Indium Tin Oxide) are formed for each sub-pixel region SG. A TFD (Thin Film Diode) element 21 as a two-terminal element is formed at the corner position of each pixel electrode 10 on the inner surface of the lower substrate 1. Furthermore, on the inner surface of the lower substrate 1, data lines 32a and 32b made of chromium or the like are formed on both sides of each pixel electrode 10, respectively. In the cross-sectional configuration of FIG. 2, each pixel electrode 10 is electrically connected to the data line 32 a via the corresponding TFD element 21. In the cross section different from FIG. 2, each pixel electrode 10 is electrically connected to the data line 32 b instead of the data line 32 a via the corresponding TFD element 21. Thus, as shown in FIG. 1, the element substrate 91 is provided with a pair of data lines 32a and 32b on both sides for each pixel electrode group forming a column in the Y direction. There is no. In addition, routing wirings 31 made of chromium or the like are formed on the left and right peripheral edge portions on the inner surface of the lower substrate 1. One end side of the routing wiring 31 extends into the seal member 3 and is electrically connected to the conduction member 7 mixed in the seal member 3. An alignment film 17 is formed on the inner surface of the lower substrate 1, the data lines 32 a and 32 b, the TFD element 21, the pixel electrode 10, and the like.

  On the other hand, on the inner surface of the upper substrate 2, colored layers 6R, 6G, and 6B made of any of the three colors R (red), G (green), and B (blue) are formed for each sub-pixel region SG. ing. The colored layers 6R, 6G, and 6B are opposed to the corresponding pixel electrodes 10. A color filter is constituted by the colored layers 6R, 6G, and 6B. A pixel region G indicates a region for one color pixel composed of R, G, and B sub-pixels. In the following description, when a colored layer is specified regardless of color, it is simply referred to as “colored layer 6”, and when a colored layer is specified by distinguishing colors, it is described as “colored layer 6R”.

  In addition, on the inner surface of the upper substrate 2 corresponding to each colored layer 6, adjacent subpixel regions SG are separated to prevent light from being mixed from one subpixel region SG to the other subpixel region SG. Therefore, the black light shielding layer BM is formed. The black light shielding layer BM is preferably made of a black resin material, for example, a black pigment dispersed in a resin. In the present invention, instead of this, an overlapping light shielding layer (not shown) formed by overlapping R, G, and B colored layers may be used.

  An overcoat layer 19 made of an acrylic resin or the like is formed on the inner surfaces of the colored layer 6 and the black light shielding layer BM. The overcoat layer 19 has a function of protecting the colored layer 6 and the like from corrosion and contamination due to chemicals and the like used during the manufacturing process of the liquid crystal display device 100. A scanning line 8 is formed on the inner surface of the overcoat layer 19. An alignment film (not shown) is formed on the inner surface of the scanning line 8 or the like.

  A polarizing plate 11 is disposed on the outer surface of the lower substrate 1, while a polarizing plate 12 is disposed on the outer surface of the upper substrate 2. Further, a backlight 15 as a lighting device is disposed below the polarizing plate 11. The backlight 15 is preferably a point light source such as an LED (Light Emitting Diode) or a combination of a linear light source such as a cold cathode fluorescent tube and a light guide plate.

  Now, when transmissive display is performed in the liquid crystal display device 100 of the present embodiment, the illumination light emitted from the backlight 15 travels along the path T shown in FIG. 2, and passes through the pixel electrode 10 and the colored layer 6 and the like. Pass through to the observer. In this case, the illumination light has a predetermined hue and brightness by passing through the colored layer 6. Thus, a desired color display image is visually recognized by the observer.

(Electrode and wiring configuration etc.)
Next, with reference to FIGS. 3 to 7 and the like, the configuration of the electrodes and wirings of the element substrate 91 will be described. FIG. 3 is a plan view showing the configuration of electrodes and wirings of the element substrate 91 when the element substrate 91 is observed from the front direction (that is, the upper side in FIG. 2). In FIG. 3, other elements other than the electrodes and wiring are not shown for convenience of explanation.

  In FIG. 1, a region where one pixel electrode 10 and a scanning electrode 8 facing the pixel electrode 10 intersect constitute a sub-pixel region SG which is a minimum unit of display. An area in which a plurality of sub-pixel areas SG are arranged in a matrix in the vertical direction and the horizontal direction in the drawing is an effective display area V (area surrounded by a two-dot chain line). In the effective display area V, images such as letters, numbers, and figures are displayed. 1 and 3, a region defined by the outer periphery of the liquid crystal display device 100 and the effective display region V is a frame region 38 that does not contribute to image display.

  The element substrate 91 includes a plurality of TFD elements 21, a plurality of pixel electrodes 10, a plurality of routing wires 31, a plurality of data lines 32a and 32b, a plurality of Y driver ICs 33, an X driver IC 34, a plurality of external connection terminals 35, and the like. It has.

  On the projecting region 36 of the element substrate 91, a Y driver IC 33 and an X driver IC 34 are mounted via, for example, an ACF (Anisotropic Conductive Film). In FIG. 3, the direction from the side 91a on the projecting region 36 side of the element substrate 91 to the opposite side 91c is defined as the Y direction, and the direction from the side 91d toward the opposite side 91b is defined as the X direction.

  A plurality of external connection terminals 35 are formed on the overhang region 36. Each input terminal (not shown) of the Y driver IC 33 and the X driver IC 34 is connected to the plurality of external connection terminals 35 through conductive bumps. The external connection terminal 35 is connected to a wiring board (not shown) such as a flexible printed board via ACF or solder. Thereby, for example, signals and power are supplied to the liquid crystal display device 100 from an electronic device such as a mobile phone or an information terminal.

  An output terminal (not shown) of each Y driver IC 33 is connected to a plurality of lead wirings 31 through conductive bumps. On the other hand, an output terminal (not shown) of each X driver IC 34 is connected to a plurality of data lines 32a and 32b via conductive bumps. The functions of each Y driver IC 33 and X driver IC 34 will be described later.

  Each routing wiring 31 includes a main line portion 31a and a bent portion 31b that bends substantially at right angles to the main line portion 31a. Each main line portion 31 a is formed so as to extend in the Y direction from the overhanging region 36 in the frame region 38. Further, the main line portions 31a are formed at regular intervals. Each bent portion 31 b extends in the frame region 38 to the seal member 3 positioned in the X direction and on the left and right. The end portions of the respective bent portions 31 b are electrically connected to the conducting member 7 in the seal member 3.

  Each of the data lines 32a and 32b is a straight wiring and is formed so as to extend in the Y direction from the overhanging area 36 to the effective display area V. Each data line 32a is arranged on the left side of the pixel electrode group forming a column in the Y direction, and each data line 32b is arranged on the right side of the pixel electrode group forming a column in the Y direction. Yes.

  Each TFD element 21 is disposed at the lower left corner position or the lower right corner position of each pixel electrode 10. Each TFD element 21 is electrically connected to the corresponding pixel electrode 10 and the data line 32a or 32b.

  Next, functions and the like of each Y driver IC 33 and X driver IC 34 will be described.

  Each Y driver IC 33 sequentially and exclusively scans each scanning line 8 via each routing wiring 31 and the like by a so-called one-line inversion driving method. Each Y driver IC 33 applies a scanning potential VA to each scanning line 8, and the X driver IC 34 applies a signal potential VB to each data line 32a and 32b. The potentials VA and VB will be described with reference to FIG. First, a scanning potential VA as shown in FIG. 5A is applied to each scanning line 8. For each line selection period T, each scanning line 8 is sequentially selected exclusively, and any potential having a potential difference of ± Vsel with respect to a certain common potential VGND, that is, a voltage is applied. This voltage, ± Vsel, is called a selection voltage. Then, after the line selection period T, any potential having a voltage of ± Vhld with respect to the common potential VGND is applied to each scanning line 8. Here, when the potential at the time of selection is VGND + Vsel, the potential of VGND + Vhld is applied, and when the potential at the time of selection is VGND−Vsel, the potential of VGND−Vhld is applied. This voltage Vhld is called a holding voltage (or non-selection voltage). In addition, a period in which all the scanning lines 8 are selected in a round is called a field period. In the next field period, the scanning lines 8 are sequentially and exclusively used by using a selection voltage having a characteristic opposite to that of the previous field period. Select.

  As shown in FIG. 5B, the X driver IC applies any potential having a voltage of ± Vsig with respect to the common potential VGND, as shown in FIG. 5B, to the data lines 32a and 32b. Here, when the potential applied to the scanning line 8 selected in a certain selection period is VGND + Vsel, VGND−Vsig is used as the on potential Von, and VGND + Vsig is used as the off potential Voff. Further, when the potential applied to the scanning line 8 selected in a certain selection period is VGND−Vsel, VGND + Vsig is used as the on potential Von, and VGND−Vsig is used as the off potential Voff.

  That is, the waveform of the signal potential VB in each line selection period T is set according to the gradation of each pixel in the column related to the data lines 32a and 32b. First, the signal potential VB is set in each line selection period. Each T is divided into an ON section and an OFF section, and is set to the ON potential Von in the ON section and to the OFF potential Voff in the OFF section. That is, the signal potential VB is pulse width modulated in accordance with the gradation value. The higher the gradation to be given to the pixel electrode 10 (the darker in the normally white mode), the larger the proportion occupied by the ON section.

  Next, the interelectrode voltage VAB of the scanning line 8 and the data lines 32a and 32b is indicated by a solid line in FIG. As shown, the absolute value of the interelectrode voltage VAB increases during the selection period of the pixel electrode 10. Further, the liquid crystal layer voltage VLC applied to the liquid crystal layer 4 is indicated by hatching in FIG. When the liquid crystal layer voltage VLC changes, the capacitance formed by the liquid crystal layer 4 must be charged and discharged, so that the liquid crystal layer voltage VLC changes in a transient response to the interelectrode voltage VAB. In FIG. 5C, the voltage VNL is the difference between the interelectrode voltage VAB and the liquid crystal layer voltage VLC, that is, the terminal voltage of the TFD element 21.

  An example of the signal potential VB in the present embodiment is shown in FIG. In FIG. 6A, the line selection period T is composed of an on section and an off section. Further, since the scanning potential VA is as shown in FIG. 6A, the interelectrode voltage VAB and the liquid crystal layer voltage VLC are as shown in FIG. 6B.

  FIG. 7 shows driving waveforms in the gradation display in the liquid crystal display device 100. As described above, in the liquid crystal display device 100, gradation display is performed by pulse width modulation of the drive voltage applied to the liquid crystal layer 4. An example of drive waveforms for one line (1T) in the case of white display, gray display, and black display is shown in the upper part of FIG. In this example, it is assumed that the liquid crystal display device 100 is normally white.

  The scanning line drive waveform 61 is a pulse waveform applied to the scanning line 8 and defines the scanning potential VA. The data line drive waveform 62 is a pulse waveform applied to the data lines 32a and 32b, and defines the signal potential VB. As described above, a potential difference between the scanning line 8 and the data line 32a or 32b, that is, an interelectrode potential is applied to the liquid crystal layer 4. That is, the total voltage of the scanning line driving waveform 61 and the data line driving waveform 62, that is, the interelectrode voltage shown in the combined voltage waveform shown in the lower part of FIG. 7 is applied to the liquid crystal layer 4. In the lower part of FIG. 7, a change in the actual voltage level (liquid crystal layer voltage level) of the liquid crystal layer 4 is shown as a liquid crystal layer voltage waveform 63. Since the liquid crystal layer 4 has a delay from the voltage application to the change in the orientation of the liquid crystal molecules, a corresponding transient response occurs, and the liquid crystal layer voltage waveform 63 shown in the lower part of FIG. 7 is applied to the liquid crystal layer 4. Will be. The gradation of the liquid crystal display device 100 changes according to the liquid crystal layer voltage level. Since the liquid crystal display device 100 of the present embodiment is normally white, white display is performed when the liquid crystal layer voltage level is low, black display is displayed when the voltage level is high, and gray display (halftone display) is intermediate. As can be understood from the upper waveform in FIG. 7, the halftone level in gray display (halftone display) is controlled by the pulse width of the data line drive waveform 62.

  Next, the configuration of the electrodes of the color filter substrate 92 will be described with reference to FIG.

  As shown in FIG. 4, each scanning line 8 includes a first portion 8a, a second portion 8b, and a third portion 8c, and has a U-shaped planar shape.

  The first portion 8a and the third portion 8c have the same shape and are formed to extend in a direction (X direction) substantially orthogonal to the extending direction of the data lines 32a and 32b. The length (width) in the Y direction of the first portion 8a and the length (width) in the Y direction of the third portion 8c are set to be at least the length of the pixel electrode 10 in the Y direction. . The first portion 8a and the third portion 8c are arranged to face each other with a plurality of pixel electrodes 10 corresponding to one row. The second portion 8b is formed so as to extend in the extending direction (Y direction) of the data lines 32a and 32b, and connects one end side of the first portion 8a and one end side of the third portion 8c. . Further, the second portion 8 b is disposed in the seal member 3 located on the left side or the right side of the paper surface, and is electrically connected via the conducting member 7 in the seal member 3.

  Each scanning line 8 is arranged so that the Y driver IC 33 alternately meshes in the direction in which the scanning line 8 is sequentially scanned and in the extending direction of the data lines 32a and 32b.

  1 and 4, when attention is paid to one scanning line 8 having an opening on the right side of the drawing surface among a certain set of scanning lines 8, the first portion 8 a of one scanning line 8 and the one The first portion 8a of the other scanning line 8 having an opening on the left side of the paper is disposed between the third portion 8c and the third portion 8c of the one scanning line 8 below the third portion 8c. A third portion 8c of the other scanning line 8 is arranged. That is, the liquid crystal display device 100 of the present invention has a plurality of sets of scanning lines 8 arranged so as to mesh with each other in a comb-teeth shape.

  FIG. 1 shows a state where the color filter substrate 92 and the element substrate 91 described above are bonded together via the seal member 3. As shown in the figure, each scanning line 8 of the color filter substrate 92 is orthogonal to each data line 32 a and 32 b of the element substrate 91. Each scanning line 8 is planar with the pixel electrode 10 corresponding to two rows, with the pixel electrode 10 corresponding to one row located in the opening between the first portion 8a and the third portion 8c being separated. It overlaps with.

  Further, the second portions 8b of the scanning lines 8 of the color filter substrate 92 and the routing wirings 31 of the element substrate 91 are alternately overlapped between the left side and the right side as shown in FIG. The second portion 8 b of the scanning line 8 and each routing wiring 31 are vertically connected via the conductive member 7 in the seal member 3. That is, conduction between each scanning line 81 of the color filter substrate 92 and each routing wiring 31 of the element substrate 91 is alternately realized between the left side and the right side as shown in the figure. In this way, each scanning line 8 on the color filter substrate 92 is electrically connected to each Y driver IC 33 located on the left and right sides of the drawing via each lead wiring 31 of the element substrate 91.

(Scanning line wiring structure)
Next, with reference to FIG. 8 and the like, the wiring structure of the scanning line which characterizes the present invention will be described. FIG. 8 is a plan view schematically and partially enlarged showing the liquid crystal display device 100 in FIG. In FIG. 8, the X direction corresponds to the row direction, and the Y direction corresponds to the column direction. FIG. 8 shows only the minimum elements necessary for explanation. In the following description, elements of the liquid crystal display device 100 described above are denoted by the same reference numerals, and description thereof is omitted or simplified.

  The pixel electrodes 10 are arranged in a matrix on the lower substrate 1. A parasitic capacitance C1 is formed between the pixel electrodes 10 adjacent to each other in the Y direction. That is, the pixel electrodes adjacent to each other in the Y direction are capacitively coupled by the parasitic capacitance C1 existing therebetween.

  Each data line 32a is arranged on the left side of the pixel electrode group (hereinafter also referred to as “Y-direction pixel electrode group”) arranged in the Y direction on the lower substrate 1 and extends in the Y direction. It is formed as follows. On the other hand, each data line 32b is disposed on the lower substrate 1 on the right side of the Y-direction pixel electrode group and extends in the Y direction. In other words, a set of data lines 32a and 32b is formed on both sides of any one Y-direction pixel electrode group.

  Each TFD element 21 is arranged at the position of the lower left corner or the lower right corner of each pixel electrode 10 for each unit of the pixel electrodes 10 corresponding to two rows, and each corresponding pixel electrode 10 and each data line. It is electrically connected to 32a or 32b. In other words, each TFD element 21 disposed at the lower left corner of each pixel electrode 10 is electrically connected to the data line 32 a located on the left side of each pixel electrode 10 and is connected to the right side of each pixel electrode 10. Each TFD element 21 arranged at the position of the lower corner is electrically connected to a data line 32b located on the right side of each pixel electrode 10.

  With such a configuration, in FIGS. 1 and 8, the address of the pixel electrode 10 located on the upper side of the paper is the first line, and the address of the pixel electrode 10 located on the lower side of the paper is N (N: natural number, the same applies hereinafter). In the case of the row, of the set of data lines 32 a and 32 b provided on both sides of the pixel electrode 10, the data line 32 a located on the left side of the pixel electrode 10 passes through each TFD element 21 (4N− 3) The data lines 32b that are electrically connected to the pixel electrodes 10 corresponding to the row and the (4N-2) row and located on the right side of the pixel electrode 10 pass through the TFD elements 21 ( 4N-1) are electrically connected to the pixel electrodes 10 corresponding to the rows and 4n rows.

  On the other hand, on the upper substrate 2, a plurality of scanning lines 8 (part corresponding to a two-dot chain line) that characterize the present invention are formed.

  Each scanning line 8 is provided corresponding to each row of the pixel electrode 10, and the scanning line 8 is skipped by one row and connected every two rows, and the Y driver IC 33 sequentially scans the scanning line 8. Are arranged so as to alternately mesh with each other. In other words, each scanning line 8 is planarly overlapped with the pixel electrode 10 corresponding to two rows, with the pixel electrode 10 corresponding to one row being separated. Each scanning line 8 has a U-shaped planar shape, and includes a first portion 8a, a second portion 8b, and a third portion 8c. The first portion 8a and the third portion 8c extend in the X direction, and are opposed to the pixel electrodes 10 corresponding to one row at intervals corresponding to one row of the pixel electrodes 10, respectively. . The configuration of the second portion 8b is as described above.

  Each scanning line 8 is arranged so as to alternately mesh in the direction in which the Y driver IC 33 sequentially scans the scanning line 8 and in the extending direction of the data lines 32a and 32b. In FIG. 8, when paying attention to one scanning line 8 having an opening on the right side of the paper surface among a set of arbitrary meshing scanning lines 8, the first portion 8a of the one scanning line 8 and the third third line. Between the portion 8c, the first portion 8a of the other scanning line 8 having an opening on the left side of the paper is disposed, and the other portion of the one scanning line 8 is below the third portion 8c. A third portion 8c of the scanning line 8 is disposed. That is, the liquid crystal display device 100 of the present invention has a plurality of sets of scanning lines 8 arranged so as to mesh with each other in a comb-teeth shape.

  Next, a specific operation and effect of the liquid crystal display device 100 according to the embodiment of the present invention will be described.

  Generally, when a one-line inversion driving method is applied to a double matrix type liquid crystal display device in which the length (width) of each scanning line in the Y direction is set to a length corresponding to two pixels, a striped pattern is formed. Display defects will occur. The cause of this occurrence is as described above. In other words, since the voltage polarity of the pixel electrode is inverted every two pixel pixel units, the pixel electrode row not affected by the parasitic capacitance and the pixel electrode row affected by the parasitic capacitance are alternately arranged. This is caused by fluctuations in the effective value of the generated liquid crystal.

  Therefore, in order to prevent such a display defect from occurring, all the pixel electrode rows may be configured not to be affected by the parasitic capacitance. Theoretically, when any one of the pixel electrode rows is based on the voltage polarity of the any one of the pixel electrode rows being positive or negative, the any one of the pixel electrode rows is correspondingly changed. The voltage polarity of other pixel electrode rows adjacent to the upper and lower sides of the pixel may be negative or positive. For example, as an example of such a configuration, a single-matrix liquid crystal display device having a configuration in which one scanning line is opposed to one row of pixel electrodes, to which a one-line inversion driving method is applied. Is mentioned. With such a configuration, when the liquid crystal is driven, the potential of the arbitrary one pixel electrode row and the potential of the other adjacent pixel electrode row have the same magnitude and the polarity is inverted. Both potentials cancel each other. As a result, it is possible to suppress fluctuations in the effective value of the liquid crystal, and it is possible to prevent occurrence of striped display defects.

  In consideration of such a viewpoint, in the present invention in which the double matrix method is applied, it is assumed that the one-line inversion driving method is applied, and the voltage polarity of the pixel electrode 10 is switched for each row unit of the pixel electrode. Further, the shape of the scanning line 8 is devised to prevent a striped display defect from occurring.

  That is, in the present invention, each scanning line 8 is provided corresponding to each row of the pixel electrode 10, the scanning line 8 is skipped by one row, and the scanning line 8 is connected every two rows. Are arranged so as to alternately mesh with each other in the scanning direction. In other words, each scanning line 8 is formed so as to planarly overlap the pixel electrode 10 corresponding to two rows, with the pixel electrode 10 corresponding to one row interposed therebetween. The scanning lines 8 are arranged so that the Y driver IC 33 alternately meshes in the direction in which the scanning lines 8 are sequentially scanned and in the extending direction of the data lines 32a and 32b.

  More specifically, as described above, each scanning line 8 has a U-shaped planar shape, and includes a first portion 8a, a second portion 8b, and a third portion 8c. The first portion 8a and the third portion 8c are formed so as to extend in a direction substantially orthogonal to the extending direction of the data lines 32a and 32b, and each of the first portion 8a and the third portion 8c includes a plurality of lines corresponding to one row. It arrange | positions so that the pixel electrode 10 may be opposed. For this reason, the first portion 8a and the third portion 8c overlap the pixel electrodes corresponding to the corresponding one row in a planar manner. The second portion 8b connects one end side of the first portion 8a and one end side of the third portion 8c, and leads the routing wiring 31 and each Y driver IC 33 via the conductive member 7 in the seal member 3. Electrically connected.

  1, 4, and 8, when attention is paid to one scanning line 8 having an opening on the right side of the paper surface among a set of scanning lines 8 that mesh with each other, the first portion of one scanning line 8 Between the first portion 8c and the third portion 8c, the first portion 8a of the other scanning line 8 having an opening on the left side of the sheet is disposed, and the third portion 8c of the first scanning line 8 is disposed. A third portion 8c of the other scanning line 8 is arranged below the other side. That is, the present invention has a plurality of sets of scanning lines 8 arranged so as to mesh with each other in a comb-teeth shape. In the liquid crystal display device 100 of the present invention having the above-described configuration, the scanning lines 8 are sequentially and exclusively scanned based on the one-line inversion driving method.

  Now, in the liquid crystal display device 100 shown in FIG. 8, based on the one-line inversion driving method, the scanning line 8 corresponding to Y1 and Y3 has a potential corresponding to positive polarity, and the scanning line 8 corresponding to Y2 and Y4 has Potentials corresponding to the negative polarity are respectively applied. For this reason, a potential having the same polarity as each of the scanning lines 8 is applied to the pixel electrode 10 that overlaps the scanning lines 8 in a plane.

  Here, when focusing on the pixel electrode 10 that overlaps the scanning line 8 related to Y1 and the pixel electrode 10 that overlaps the scanning line 8 related to Y2, the first portion 8a of the scanning line 8 related to Y1. And the pixel electrode 10 that overlaps the first portion 8a of the scanning line 8 related to Y2 (referred to as “pixel electrode 10b” for convenience). ) Between the pixel electrode 10b and the third portion 8c of the scanning line 8 related to Y1 (referred to as “pixel electrode 10c” for the sake of convenience) between the pixel electrode 10b and Y2 Parasitic capacitances C1 exist between the pixel electrodes 10 (referred to as “pixel electrodes 10d” for convenience) that overlap the third portion 8c of the scanning line 8 in a planar manner.

  For this reason, a potential corresponding to the negative polarity of the pixel electrode 10b circulates through the parasitic capacitance C1 on the pixel electrode 10a side, and conversely, a potential corresponding to the positive polarity of the pixel electrode 10a on the pixel electrode 10b side. Will circulate through the parasitic capacitance C1. Here, since these potentials have the same magnitude and opposite polarity, the potentials cancel each other. In addition, due to the same action as described above, a potential corresponding to the positive polarity of the pixel electrode 10c circulates through the parasitic capacitance C1 on the pixel electrode 10b side, and conversely, the negative electrode of the pixel electrode 10b on the pixel electrode 10c side. The potential corresponding to the sex goes around through the parasitic capacitance C1. For the same reason as described above, their potentials cancel each other. Further, due to the same action as described above, a potential corresponding to the negative polarity of the pixel electrode 10d is circulated through the parasitic capacitance C1 on the pixel electrode 10c side, and conversely, on the pixel electrode 10d side, the positive electrode of the pixel electrode 10c is provided. The potential corresponding to the sex goes around through the parasitic capacitance C1. For the same reason as described above, their potentials cancel each other. Such an effect also occurs in the pixel electrode 10 that overlaps the scanning line 8 related to Y3 in a plane and the pixel electrode 10 that overlaps planarly to the scanning line 8 related to Y4.

  Due to the above-described action, each pixel electrode 10 is not affected by the parasitic capacitance C1, and thus the fluctuation of the effective value of the liquid crystal can be suppressed. Therefore, it is possible to prevent a display defect in a striped pattern (horizontal stripe) from occurring.

[Modification]
In the above-described embodiment, in particular, each scanning line 8 is provided corresponding to each row of the pixel electrode 10, the scanning line 8 is skipped by one row, connected every two rows, and the Y driver IC 33 scans. The lines 8 are arranged so as to alternately mesh with each other in the scanning direction. In other words, each scanning line 8 is formed so as to planarly overlap the pixel electrode 10 corresponding to two rows, with the pixel electrode 10 corresponding to one row interposed therebetween, and Each scanning line 8 is arranged so that the Y driver IC 33 alternately meshes in the direction in which the scanning line 8 is sequentially scanned and in the extending direction of the data lines 32a and 32b.

  However, the configuration of the present invention is not necessarily limited to the above configuration. Here, a liquid crystal display device 200 according to another embodiment to which the present invention can be applied will be briefly described with reference to FIG. FIG. 9 is a partial plan view schematically showing the configuration of the liquid crystal display device 200. In the following, the same elements as those of the liquid crystal display device 100 are denoted by the same reference numerals, and the description thereof is omitted or simplified.

  When attention is paid to the scanning line 8 corresponding to Y2 and the scanning line 8 corresponding to Y4 in the liquid crystal display device 200, the liquid crystal display device 200 scans corresponding to Y2 to which a potential corresponding to negative polarity is applied. The third portion 8c of the line 8 and the first portion 8a of the scanning line 8 corresponding to Y4 to which a potential corresponding to negative polarity is applied are arranged adjacent to each other in the Y direction. That is, in the liquid crystal display device 200, generally, the potential corresponding to the negative polarity is applied, and the third portion 8c of the scanning line 8 corresponding to any one even address number is also the potential corresponding to the negative polarity. The applied first portion 8a of the scanning line 8 corresponding to the next even address number is arranged so as to be adjacent to each other in the Y direction. This is different from the configuration of the liquid crystal display device 100 described above, and other configurations are the same as the configuration of the liquid crystal display device 100 described above.

  Therefore, the pixel electrode 10 facing the third portion 8c of the scanning line 8 corresponding to any one even address number and the pixel facing the first portion 8a of the scanning line 8 corresponding to the next even address number. The potential corresponding to the negative polarity goes around the electrode 10 via the parasitic capacitance C1, and the effect of the present invention cannot be obtained at that portion. In addition, the same operation effect as said liquid crystal display device 100 can be acquired except the part. As a result, the liquid crystal display device 200 is slightly inferior in display quality to the liquid crystal display device 100 described above, but the present invention can also be applied to the liquid crystal display device 200 having such a configuration. .

  In the present invention, instead of this form, the potential corresponding to the positive polarity is applied, the third portion 8c of the scanning line 8 corresponding to any one odd address number, and the potential corresponding to the positive polarity. The first portion 8a of the scanning line 8 corresponding to the next odd address number to be applied may be arranged adjacent to each other in the Y direction.

The third portions 80c are connected to the TFT elements 450 connected to the pixel electrodes 10 in the (4N) rows.

  The data line 32a is electrically connected to each pixel electrode 10 corresponding to the (4N-3) row and the (4N-2) row via each TFT element 450, and the data line 32b is connected to each TFT. It is electrically connected to each pixel electrode 10 corresponding to the (4N−1) row and the 4n row through the element 450.

  In the liquid crystal display device 200 having the above-described configuration, the same operational effects as those of the liquid crystal display device 100 described above can be obtained.

  That is, here, when attention is paid to the pixel electrode 10 connected to the gate line 80 related to Y1 via the TFT element 450 and the pixel electrode 10 connected to the gate line 80 related to Y2 via the TFT element 450. , The pixel electrode 10 (referred to as “pixel electrode 10a” for convenience) connected to the first portion 80a of the gate line 80 related to Y1 via the TFT element 450, and the first portion 80a of the gate line 80 related to Y2. Between the pixel electrode 10 (referred to as “pixel electrode 10b” for convenience) connected via the TFT element 450, the pixel electrode 10b and the third portion 80c of the gate line 80 related to Y1 are connected via the TFT element 450. The pixel electrode 10 (referred to as “pixel electrode 10c” for convenience) is connected to the pixel electrode 10c and the third portion 80c of the gate line 80 related to Y2 via the TFT element 450.

  For this reason, a potential corresponding to the negative polarity of the pixel electrode 10b circulates through the parasitic capacitance C1 on the pixel electrode 10a side, and conversely, a potential corresponding to the positive polarity of the pixel electrode 10a on the pixel electrode 10b side. Will circulate through the parasitic capacitance C1. Here, since these potentials have the same magnitude and opposite polarity, the potentials cancel each other. In addition, due to the same action as described above, a potential corresponding to the positive polarity of the pixel electrode 10c circulates through the parasitic capacitance C1 on the pixel electrode 10b side, and conversely, the negative electrode of the pixel electrode 10b on the pixel electrode 10c side.
