As shown in fig. 2, if the black matrix region 32 is designed to have a zigzag structure at the edge of the panel, the area of each sub-pixel in each row of pixel units 310 closest to the black matrix region 32 can be made the same, but since the black matrix region 32 at the edge of the panel has a zigzag structure, an uneven boundary line and even a zigzag are seen at the edge of the display panel, which may affect the visual effect.

Referring to fig. 3 to 5, the liquid crystal display panel 100 of the present invention includes a first substrate 10, a second substrate 20, and a liquid crystal layer 30 disposed between the first substrate 10 and the second substrate 20.
The liquid crystal display panel 100 provided in this embodiment is suitable for a Fringe Field Switching (FFS) liquid crystal display device, in which the common electrode and the pixel electrode are formed in different layers on the same substrate (i.e., a thin film transistor array substrate), and when an electric field for display is applied between the common electrode and the pixel electrode, liquid crystal molecules rotate in a plane substantially parallel to the substrate to obtain different gray scales.

In this embodiment, the common electrode 22 on the second substrate 20 is disposed on the entire surface of the second substrate 20, and the pixel electrodes 21 are arranged in an array on the second substrate 20. In other embodiments, the common electrode 22 and the pixel electrode 21 may be both arranged in an array on the second substrate 20.
Fig. 6 is a partially enlarged perspective view of the edge of the display area of fig. 3. Referring to fig. 6, the second substrate 20 further includes a plurality of data lines 23, a plurality of scan lines 24 and a plurality of switching elements (not shown), each pixel electrode 21 is electrically connected to a corresponding data line 23 and a corresponding scan line 24 through a switching element, each data line 23 is used for applying a data voltage signal to a corresponding pixel electrode 21, and each scan line 24 is used for applying a scan voltage signal to a corresponding pixel electrode 21.
Specifically, the plurality of data lines 23 are disposed along a first direction, the plurality of scan lines 24 are disposed along a second direction perpendicular to the first direction, and the plurality of data lines 23 and the plurality of scan lines 24 are insulated and crossed to define a plurality of pixel regions, and each pixel electrode 21 is correspondingly disposed in the pixel region.
With reference to fig. 3 to 6, the liquid crystal display panel 100 has a display region 101 and a non-display region 102, the display region 101 includes a plurality of first pixel units 100a, the plurality of first pixel units 100a are close to an edge of the display region 101, each first pixel unit 100a includes a plurality of first sub-pixels 11, and a corresponding region of each first sub-pixel 11 includes a pixel electrode 21, a common electrode 22 and a switching element. The common electrode 22 corresponding to the first sub-pixel 11 not covered by the black matrix 12 in the plurality of first sub-pixels 11 includes at least one hollow portion 221, and the hollow portions 221 may be randomly or sequentially arranged on the common electrode 22, so as to balance the electric field intensity corresponding to each sub-pixel 11 in the first pixel unit 100 a; the non-display area 102 includes the black matrix 12. In the present embodiment, the black matrix 12 is disposed along the edge of the display region 101, and when the edge of the display region 101 of the liquid crystal display panel 100 is arc-shaped, the edge of the black matrix 12 is also arc-shaped.
In this embodiment, the lines constituting the hollow portion 221 include straight lines and arc-shaped lines, and in other embodiments, the lines constituting the hollow portion 221 are selected from one or both of curved lines and straight lines, that is, the hollow portion 221 may be provided in any shape as needed. For example, when the hollow portion 221 is shaped as a triangle, a quadrangle, a pentagon, or the like; when the hollow portion 221 is formed of only a curved line, it may have a circular shape, an elliptical shape, or the like; when the hollow portion 221 is formed of a straight line and a curved line, it may have a fan shape or the like.
Specifically, in the present embodiment, an example in which one first pixel unit 100a includes three first sub-pixels 11 is described. In the first pixel unit 100a, a part of the first sub-pixel 11 closest to the edge of the display region 101 is covered by the black matrix 12, and neither of the two first sub-pixels 11 adjacent to the first sub-pixel 11 is covered by the black matrix 12. Therefore, the intensity of the electric field formed in the corresponding region of the first sub-pixel 11 closest to the edge of the display region 101 is weaker than the intensity of the electric field formed in the corresponding region of the two adjacent first sub-pixels 11, and the brightness of the three first sub-pixels 11 in the first pixel unit 100a is different, which affects the display effect.
In the two first sub-pixels 11 not covered by the black matrix 12 in the first pixel unit 100a, a hollow portion 221 is disposed on the corresponding common electrode 22 on the second substrate 20, so as to weaken the electric field strength of the corresponding areas of the two first sub-pixels 11, so that the electric field strengths of the three sub-pixels 11 in the first pixel unit 100a are close to or equal to each other. In this embodiment, the hollow-out portion 221 extends along the edge direction of the display region 101, and is disposed around the circumference of the display region 101 to form two non-overlapping rings, and the distance between the two rings along the radial direction thereof is, for example, equal to or close to the width of one pixel electrode 21.
Specifically, a connecting portion 222 is disposed between two adjacent hollow portions 221 on the common electrode 22, so that the electrode portions of the common electrode 22 are connected to form a planar electrode.
In other embodiments, the number of the first sub-pixels 11 covered by the black matrix 12 in each first pixel unit 100a may be two or three. If two first sub-pixels 11 in one first pixel unit 100a are covered by the black matrix 12 and the covered areas are equal, the hollow part 221 is only arranged on the first sub-pixels 11 in the first pixel unit 100a which are not covered by the black matrix 12; if two first sub-pixels 11 in one first pixel unit 100a are covered by the black matrix 12 and the covered areas are not equal, the hollow portions 221 need to be disposed on the fewer first sub-pixels 11 covered by the black matrix 12 and the first sub-pixels 11 not covered by the black matrix 12, and the areas of the hollow portions 221 are not equal. Similarly, if three first sub-pixels 11 in one first pixel unit 100a are all covered by the black matrix 12, the hollow portions 221 are correspondingly arranged according to the covered area of each first sub-pixel 11, and if three first sub-pixels 11 in one first pixel unit 100a are all covered by the black matrix 12, the hollow portions 221 are arranged in the adjacent first pixel units 100 a. Therefore, the electric field intensity in the region corresponding to each first sub-pixel 11 in each first pixel unit 100a is balanced, so that the light transmittance of each first sub-pixel 11 in each first pixel unit 100a is equal.
Referring to fig. 6, the display area 101 of the lcd device further includes a plurality of second pixel units 100b, and the second pixel units 100b are disposed adjacent to the first pixel units 100a and far away from the black matrix 12. Each second pixel unit 100b includes a plurality of second sub-pixels 13, and the width of each first sub-pixel 11 in each first pixel unit 100a is equal to the width of each second sub-pixel 13 in each second pixel unit 100 b. Specifically, the light transmission areas of the respective second sub-pixels 13 located in each second pixel unit 100b are all equal.
FIG. 7 is a diagram of a portion of a pixel structure of a liquid crystal display panel according to a second embodiment of the present invention. Referring to fig. 7, a difference between the present embodiment and the first embodiment is that in the present embodiment, the plurality of hollow portions 221 disposed on the common electrode 22 are not disposed around the circumference of the display region 101, and the plurality of hollow portions 221 are disposed in the corresponding first sub-pixels 11 according to the area of the common electrode 22 corresponding to each first sub-pixel 11 that needs to be hollowed out.
In this embodiment, the hollow portion 221 is a quadrilateral. In other embodiments, the lines constituting the hollowed-out portions 221 may be selected from either or both of a curved line and a straight line, i.e., the hollowed-out portions 221 may be provided in any shape as needed. For example, when the hollow portion 221 is formed by only straight lines, it may have a shape of a triangle, a quadrangle, a pentagon, or the like; when the hollow portion 221 is formed of only a curved line, it may have a circular shape, an elliptical shape, or the like; when the hollow portion 221 is formed of a straight line and a curved line, it may have a fan shape or the like.
With reference to fig. 7, each of the first pixel units 100a includes a plurality of first sub-pixels 11. Each first pixel cell 100a is disposed near an edge of the display area 101. In this embodiment, the first pixel unit 100a includes three first sub-pixels 11. When the first sub-pixel 11 closest to the display region 101 in one first pixel unit 100a is partially covered by the black matrix 12, at least one hollow portion 221 is respectively disposed on the common electrode 22 corresponding to two adjacent first sub-pixels 11 of the first sub-pixel 11.
When the portion of the first sub-pixel 11 closest to the display area 101 covered by the black matrix 12 occupies 10% of the opening area of the first sub-pixel 11, and if the simulation result shows that each hollow portion 221 can reduce the light transmittance by 10%, therefore, to balance the light transmittance of each sub-pixel in the first pixel unit 100a, one hollow portion 221 needs to be disposed in the area of the common electrode 22 corresponding to each first sub-pixel 11 not covered by the black matrix 12.
When the portion of the first sub-pixel 11 closest to the display area 101 covered by the black matrix 12 occupies 20% of the opening area of the first sub-pixel 11, and if the simulation result shows that each hollow portion 221 can reduce the light transmittance by 10%, therefore, in order to balance the light transmittance of each sub-pixel in the first pixel unit 100a, two hollow portions 221 need to be disposed in the area of the common electrode 22 corresponding to each first sub-pixel 11 not covered by the black matrix 12.
In other embodiments, the number of the first sub-pixels 11 covered by the black matrix 12 in each first pixel unit 100a may be two or three, and at this time, the hollow portion 221 is disposed on the common electrode 22 corresponding to at least two first sub-pixels 11 in the first pixel unit 100a to balance the electric field intensity in the area corresponding to each first sub-pixel 11 in each first pixel unit 100a, so that the light transmittance of each first sub-pixel 11 in the first pixel unit 100a is equal.
The invention also provides a liquid crystal display device which comprises the liquid crystal display panel 100.
According to the liquid crystal display panel 100 provided by the invention, aiming at the first pixel units 100a close to the edge of the display area 101, the hollow parts 221 are arranged on the common electrode 22 which is arranged opposite to each first pixel unit 100a, so that the electric field intensity of liquid crystal in each first sub-pixel 11 in each first pixel unit 100a is equal, namely the light transmittance of each first sub-pixel 11 is equal, the color display of the edge of the liquid crystal display panel 100 is uniform, the black matrix 12 does not need to be arranged into a zigzag structure, sawteeth are prevented from being seen at the edge of the liquid crystal display panel 100, the visual effect of the edge of the liquid crystal display panel 100 is improved, and the problem that the color of the existing special-shaped display panel is uneven or the sawteeth appear at the edge is solved.
