Description of the invention j: 1) ~ Field of invention The present invention relates to, for example, a liquid crystal display device suitable for a light valve for projection, and a projector using the same. BACKGROUND OF THE INVENTION In recent years, a liquid crystal display device provided with a liquid crystal panel is generally used as a flat panel display. This liquid crystal display device can be used as a light pipe of a projector. Figure 4 shows the internal structure of the housing 42 of a full-color projector 41 that uses a liquid crystal display device as a light pipe. The light emitted from the light source passes through ultraviolet and infrared cut-off filters 44 and becomes only visible light. First, Into a dichroic mirror (red, cyan reflection, green pass) 45. Here, only green light is transmitted, and reflected by the mirror 46 is incident on the green liquid crystal display device 48. On the other hand, the light reflected by the dichroic mirror 45 is incident on the dichroic mirror 47, where the cyan light is reflected and enters the cyan liquid crystal display device 49, and the red light passes through and is incident on Liquid crystal display device 50 for red. The light that is incident on the liquid crystal display device 48 for green will be transmitted through the green liquid crystal display device 48 by the Central Bureau of the Ministry of Economic Affairs, and will pass through the green liquid crystal display device 48, and then through the dichroic mirror (cyan reflection, green transmission) 5 1 and It is reflected by a dichroic mirror (cyan, green reflection, red transmission) 5 2 and then enters the projection lens 54. The light that has entered the cyan liquid crystal display device 49 passes through the cyan liquid crystal display device 49 and is sequentially reflected by the dichroic mirrors 51 and 52 and is incident on the projection lens 54. The light incident on the red liquid crystal display device 50 passes through the red liquid crystal display device 50 and is reflected by the mirror 53 and then transmitted through the dichroic mirror 52 to the projection lens 54 ° image _-4 -__ This paper Standards apply to Chinese National Standard (CNS) A4 (210X297 mm) ^ 06201 A7 B7 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention () The light that is separated into various colors will be synthesized and transmitted from the projection lens 4 Projected on a screen without illustration. At this time, among the three liquid crystal display devices 48, 49, 50, the number of reflection times of light transmitted through the green liquid crystal display device 48 and the red liquid crystal display device 50 is once received by the dichroic mirror 52 or the mirror 53. Reflection, and the appearance of the image becomes consistent. However, the number of times of reflection of light transmitted through the cyan liquid crystal display device 49 is that the dichroic mirror 51 and the dichroic mirror 52 are reflected twice. Therefore, the relationship between the left and right images of other liquid crystal display devices 48, 50 is reversed. That is, to provide a plurality of liquid crystal display devices having a plurality of display devices inside a projector, it is necessary to use two types of liquid crystal display devices in which the left and right sides of the image are inversely related to each other. In addition, the use form of the projector is, as shown in Fig. 5, a front projection type and a rear projection type as shown in Fig. 6. The front projection type projects an image from the front of the screen 56 by the projector 5 5 while the rear projection type projects the image output by the projector 5 7 disposed on the back side of the screen 5 6 on the reflector 5 8, 5 9 Reflection is projected. Furthermore, the images' output by the projector 55 and the rear-projection type projector 5 7 are in a reverse relationship. In addition, even the front projection type, there are a floor-standing type shown in FIG. 5 and a ceiling-mounted type shown in FIG. 7. The floor-standing type projector 5 5 is different from the ceiling-mounted type projector 6. The output image has a reversed relationship between left and right and up and down. That is, depending on the usage form of the projector, the direction of the image displayed by the liquid crystal display device inside the projector must be reversed from side to side or from side to side.

Description of the invention χ1 The employee consumer cooperative of the Central Standards Bureau of the Ministry of Economic Affairs is printed here. If you want to reverse the direction of the image, It is sufficient if the direction of the image signal given to the pixels is reversed. That is, the shift direction of the signal line driver that drives the signal line can be switched to switch the shift direction. For example, Japan Japanese Patent Application Laid-Open No. 3_289697 cannot disclose a plurality of integrally formed driver-type liquid crystal panels for driver units for signal lines with different displacement directions. Also, the above-mentioned liquid crystal display devices for green, blue, and red 48, 4 9 5 0—A conventional liquid crystal display device commonly used is, for example, the liquid crystal display device 90 shown in FIG. 8. This display device is provided with a signal line 62 ', a scan line 63, and a transistor 65 of the display portion 64. The X driver 66 used to drive the signal line and the γ driver 67 used to drive the scan line are integrated drivers The built-in liquid crystal panel 61 is arranged on a PCB (printed circuit board) 68 whose opening is equivalent to the display portion 64. At the same time, in order to drive the signal input of the liquid crystal panel 61, the liquid crystal panel 61 61 and PCB 68 are connected by FPC (wound printed wiring) 69, and the wiring on PCB 68 is connected to the side signal input section 70. Others, as shown in Fig. 9, liquid crystal display device 91 shown in Fig. 10 , 92 (press, here, for convenience of explanation, components having the same functions as those shown in FIG. 8 are denoted by the same symbols, and the description is omitted). The liquid crystal display device 91 shown in FIG. The X driver 6 6 and the Y driver 67 are also equipped with a driver formed on a substrate and a wiring built-in liquid crystal panel 75. The liquid crystal display device 92 shown in FIG. Drivers 72, 73, and Y drive 74 are externally connected LCD panels 75. Here, change the displacement direction of the X drivers 72, 73 (please read the precautions on the back of Rose and fill out this K )-Binding.

Description of the invention i4) — '~ Reverse, and by switching the X driver used, you can Switch the shift direction. However, the three display devices 48, 49, and 50 for green and blue used as the light tube of the projector 41 shown in FIG. 4 will have characteristics when light is irradiated to the transistor of the display portion. Degradation causes a decrease in contrast. Therefore, in order to allow light to be incident from the opposite substrate side, each of the display devices 48, 49, and 50 must be installed in the housing 42. In addition, the display devices 48, 49, and 50 for green, cyan, and red are used. If the angle dependency (viewing angle characteristic) with strong contrast is used, the viewing direction of the maximum contrast (hereinafter referred to as the viewing angle) (Direction) TN (nematic twisted-line) liquid crystal panel deviating from the normal direction, the above display devices 48, 49, 50 must be installed inside the casing 42 so that the viewing angle direction of the liquid crystal panel and the incident direction of light become Consistent. If a projector equipped with a liquid crystal display device with a strong viewing angle characteristic is projected on a screen, the upper part of the liquid crystal panel (the position is optically equal) will become the lower part on the screen. The entrance direction is limited to the opposite substrate side. For example, when the light incident direction (viewing angle direction) with high contrast is changed from the opposite substrate to the TFT substrate side, the contrast at the lower part of the screen becomes higher. Therefore, if the viewing direction of each display device 48, 49, 50 and the incident direction of light are not the same for all the liquid crystal panels, the displayed color unevenness occurs due to the decrease in contrast and the difference in the maximum contrast direction. , And it will cause a significant reduction in image quality. That is, if the liquid crystal display device is used as a light pipe of a projector, the opposite substrate of the liquid crystal panel of each liquid crystal display device is arranged to emit light into this paper.

Description of the invention /), and , Must be installed inside the case, so that the viewing angle direction of the liquid crystal panel and the incident direction of light become the same. Therefore, for example, as the liquid crystal display devices 48, 49, 50 for green and cyan 'red, a liquid crystal display device 90 of the type shown in FIG. 8 is used, as shown in FIG. 11 and FIG. 〇 It is installed inside the case with the relationship of the input signals in opposite directions to each other. The displacement directions 81 and 84 of the χ driver 66 must be reversed from each other. Press, at this time, si '84 indicates the displacement direction of the χ driver 66 when viewed from the incident direction of light, and 82, 85 indicates the displacement of the γ driver 67 when viewed from the incident direction of light. Bit direction. Note that the directions of viewing angles of the liquid crystal panel 61 are that the liquid crystal panel 61 is downward and upward from the opposite substrate to the TFT substrate side, respectively. More specifically, the red and green liquid crystal display devices 48, 50 are shown in FIG. 4, and if they are installed in the housing 42 of the projector 41, they are moved for the X driver 66 and the Y driver 67. In the bit direction and the viewing angle direction, the incident direction of the light can be changed as shown in FIG. 11, and the signal input portion 70 is installed on the front side of the paper surface in FIG. 4. On the other hand, the blue liquid crystal display device 49 ° must be installed as shown in Fig. I 2 when viewed from the incident direction of light in order to shift the χ driver 66 and y driver 67 and the viewing angle direction. In addition, the signal input portion 70 becomes the paper surface inside of FIG. 4. At this time, the shifting direction of the X driver 66 can be provided with a shift register that can switch the shifting direction. For the green and red LCD display devices 48 '50, the required image is left and right. The reverse cyan liquid crystal display device 49 may share one type of liquid crystal display device 90.

Description of the invention / ) The signal input part 70 of the cyan liquid crystal display device 49 is located at the opposite position (front side of the paper surface and inner side of the paper surface in FIG. 4). In order to input 70 input signals for these signals, the wiring of the register signal input must be lengthened. Connect them, or place the board on the opposite side. If the signal line becomes longer, the display quality will decrease due to noise, etc. When the circuit board is placed on the opposite side, the projector will become larger due to the increase in space and the cooling mechanism of the liquid crystal panel 61 will occur. It becomes a complicated problem, and it is impossible to obtain benefits because of sharing. If the front projection type projector shown in FIG. 5 and the rear projection type shown in FIG. 6 are used, a liquid crystal display device used as a light pipe will cause the same problem. In order to avoid such a reduction in display quality or the size of a projector, the direction of the signal input portion 70 is changed to the same direction, and it is considered to be installed inside the casing. However, in this case, as shown in FIG. 1 and FIG. 1 As shown in FIG. 3, the shift directions 82, 88 of the Y driver 67 must be reversed from each other, and the viewing directions 83, 89 of the liquid crystal panel 61 must be reversed. At this time, it is possible to switch the shift direction of the Y driver 67, but it is also possible to have a register that can switch the shift direction. However, because the viewing angle direction of the liquid crystal panel 61 cannot be switched at will, it is necessary to have a different viewing direction.

Description of the invention, the entrance part, and the mounting member that fixes the above-mentioned liquid crystal display device to other devices, the above-mentioned installation The component system is point-symmetrical to the center of the display portion of the liquid crystal panel. The structure is provided at both ends of the above-mentioned liquid crystal display portion along the signal line direction. Since the liquid crystal panel of the above structure has a viewing angle direction in which the maximum contrast can not be changed from the normal direction, it is expected that When the transmitted light is used in a certain job, in order to obtain good contrast, the appropriate setting angle of the liquid crystal panel in which the light is incident will be determined. That is, 'if the direction of the viewing angle that can obtain the maximum contrast is consistent with the normal direction In the case of a liquid crystal panel, if the normal line of the liquid crystal panel is consistent with the incident direction of light, there is no problem even if the surface of the liquid crystal panel is turned upside down (or left and right), but if the liquid crystal panel of the above structure is suitable, When the angle is set and the top and bottom (or left and right) of the panel are set to be inverted, the contrast of the transmitted light will be deteriorated. That is, the liquid crystal panel with the above configuration must be set at an appropriate setting angle for incident light. Therefore, ' In the above structure, since the mounting member used to fix the liquid crystal device to other devices is point-symmetrical to the center of the display portion of the liquid crystal panel, the When this liquid crystal display device is fixed to other devices, the panel surface of the liquid crystal panel is rotated around the center of the display portion of the liquid crystal panel as i 8 0. The two directions' that is, the top and bottom (left and right) of the panel face each other On the contrary, it can be fixed to other devices in two directions. That is, according to the light incident direction of the fixed position of the other devices described above, the direction of the fixed liquid crystal display device is reversed, which is 11-This paper is recognized as applying the Chinese National Standard (CNS) A4 secret.

As long as one type of liquid crystal display device 15 is used, it can be used for all of the green, cyan, and red liquid crystal display devices 28, 29, and 30. At this time, only the liquid crystal display device 15 provided for the cyan display device 29 has a signal input direction for driving the liquid crystal panel 1 and is provided for the other two liquid crystal display devices 28, 30. The LCD display device is reversed from £ 15, but because the signal input section, Π is provided on the left and right, since the signal input section 11 on the opposite side is used, it can be equipped with other liquid crystal display devices 2 8 and 2 9 The liquid crystal display device 15 inputs signals in the same direction. Therefore, it will not lead to the deterioration of display quality as well as the increase in size and weight of the projector, and the complexity of the cooling mechanism. If the required image is reversed, it can be shared by a type of liquid crystal display device 15 . Moreover, since the liquid crystal display device 15 can be shared as a light pipe even between the front projection type projector 5 5 (refer to FIG. 5) and the rear projection type projector 5 7 (refer to FIG. 6). Liquid crystal display device. Also, when the above-mentioned liquid crystal display device 15 is used, it is not only the X driver 6, but the shift direction of the Y driver 7 can also be switched to the opposite direction. The front-projection type floor-standing projector 55 (refer to FIG. 5) and even the ceiling-mounted projector 60 (refer to FIG. 7) 'will not cause a reduction in display quality, and increase the size and bulk of the projector. If the cooling mechanism is complicated, the liquid crystal display device can be shared.

Description of the invention 彡 7)---- The components are configured to be rotationally symmetrical, so even when the installation direction is opposite, the liquid crystal display device is also installed. The liquid crystal display device can be shared (it is necessary to use a different liquid crystal display device if the mounting member is not a rotating object, and cannot be shared), and it is not troublesome if it is ζ ,, Λ w. By mounting the liquid crystal display device in various directions, the workability during assembly can be improved, and the cost can be further reduced. According to the above, the above embodiments are all examples, and the present inventors are not limited. For example, the connection method and signal input method of the LCD panel 1 and the PCB 8 or the signal input sections 10 and 11 are shown in the table, even with the drawings! What is shown may not be at the same time, and even the shape of the PCB 8 may be a display through which light passes through the liquid crystal panel. The shape of 卩 is sufficient. The liquid crystal panel may be different from the active matrix type liquid crystal panel. That is, the above-mentioned liquid crystal display device 15 is connected to the PCB 8 and the liquid crystal panel 1 by the EPC9 for the signal input 'required for driving the liquid crystal panel i. However, this can of course also be connected using a wire bonding method. Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs, that is, although the above-mentioned liquid crystal display device 15 uses an X, γ driver 6 ′ 7 and a liquid crystal panel 1 built in the driver, the present invention is not limited thereto. Here, for example, as shown in FIG. 3, an external connection type liquid crystal panel 1 'which connects the X driver 1 2' 1 3 'and the Y driver 1 4 from the outside may be provided, and other parts may be provided. A liquid crystal display device 16 having the same configuration as the liquid crystal display device 15 is obtained. Furthermore, even in the liquid crystal display device 16, only one of the X driver 12, 13 or the Y driver 14 may be connected from the outside, and the other may be integrated (built-in). -20- This paper size is in accordance with Chinese National Standard (CNS) A4 (210X297 mm), printed by the Consumer Cooperatives of the Central Government Bureau of the Ministry of Economic Affairs A7 ------- V. Description of Invention 发明 8) 'As above In the liquid crystal display devices 15 and 16 of this embodiment, the shift directions of the χ driver and the γ driver can be arbitrarily switched, and n is formed on both sides in order to drive the signal wheel characters required for the above-mentioned liquid crystal panel. Of the composition. Since such liquid crystal display devices 15 and 16 are used, the problems existing in projectors equipped with a plurality of liquid crystal display devices can be eliminated. That is, for example, the liquid crystal display device 90 of the type shown in FIG. 8 is as shown in FIG. 11 and FIG. 12, so that the shift direction of the χ driver (signal line driver) 66 is reversed, and the signal must also be changed. The direction of the input section 70 is reversed, and it is installed inside the cabinet. In this case, in order to correspond to the opposite position, each signal input section 70 is extended by the wiring of the register signal input, or it must be connected. Dispose the circuit board on the opposite side and input the signal from there. If this happens, there may be a reduction in display quality due to noise, etc., or an increase in the size of the projector due to the increase in space, and the complexity of the liquid crystal panel cooling mechanism. However, since this structure is adopted, since the signal input section can also be installed on the opposite side, even the signal input of the liquid crystal display device whose shift direction is reversed (the input direction is reversed from the other two pieces) ), Because the opposite signal input section is used, signals can be input from other display devices in the same direction. Therefore, even if one type of liquid crystal display device does not cause a reduction in display quality, and the projector becomes large and bulky, and the cooling mechanism is complicated, it can be shared when the image needs to be reversed. That is, there will not be any trouble. The three-chip liquid crystal display device that can be used as a light pipe in a full-color projector is shared by one type. In addition, the front-type projector and the rear-type projector Can also be shared between. As a result, this kind of liquid-21-this paper size can be applied to Chinese National Standard (CNS) A4 specification (210 × 297 mm) # ------. 1T ------ ^ •! ·-, · (Please read the precautions on the back before filling this page), 4Ci A7 B7 V.
