In order to reduce the resistance of pixel electrode 103, as shown in figure 11, multiple slits 1031 are provided on pixel electrode 103
(slit), slit 1031 extends in a first direction.In the case where array substrate 10 includes pixel electrode 103 and public electrode,
In order to keep liquid crystal molecule inclined in the horizontal direction under the driving for the horizontal component of electric field that pixel electrode 103 and public electrode generate
Turn, the initial orientation of liquid crystal molecule should be vertical with the direction of electric field that pixel electrode 103 and public electrode generate.So,
The initial orientation of liquid crystal molecule is parallel with the extending direction of slit 1031 on pixel electrode 103.Due in liquid crystal display panel 3
The initial orientation of liquid crystal molecule, therefore orientation (the alternatively referred to as side Rubbing of oriented layer are determined by the orientation of oriented layer
To) parallel with 1031 extending direction of slit, i.e., the orientation of oriented layer is vertical with data line 102.The manufacturing process of oriented layer is first
Oriented film is formed, recycles orientation cloth to be orientated oriented film, forms oriented layer.Due to the orientation and data of oriented layer
Line 102 is vertical, thus when carrying out orientation to oriented film using orientation cloth and forming oriented layer, orientation cloth is moved along first direction
It is dynamic.Since oriented film is uneven in the region for being provided with data line 102, thus it is orientated cloth and is moved through along first direction
When being provided with the region of data line 102, it may appear that orientation region blind area (Rubbing Shadow), since liquid crystal is in Rubbing
The region Shadow is uncontrolled, thus the phenomenon that will appear light leakage.In order to avoid light leakage, needed when designing black matrix pattern 202
Increase shading strip in black matrix pattern 202 to block along the width of first direction as caused by the region Rubbing Shadow
Light-leaking area.However, the width for increasing shading strip in black matrix pattern 202 will lead to aperture opening ratio decline.
Based on above-mentioned, optionally, as shown in figure 12, each pixel electrode 103 include it is multiple extend in a second direction it is narrow
Seam 1031.
Herein, slit 1031 extends in a second direction refers to that slit 1031 extends in a second direction on the whole.Some
In embodiment, pixel electrode 103 includes a farmland, and in the case, slit 1031 is linear；In further embodiments,
Pixel electrode 103 divides two farmlands, and in the case, as shown in figure 12, every slit 1031 includes the first sub- slit and second
The angle theta of sub- slit, the first sub- slit and the second sub- slit is obtuse angle.
Since slit 1031 extends in a second direction, the orientation of oriented layer is parallel with 1031 extending direction of slit, thus takes
When extending in a second direction to the orientation of layer, therefore being orientated using orientation cloth to oriented film, orientation cloth is in a second direction
It is mobile, so, just avoids and generate the region Rubbing Shadow.The leakage generated due to the region no Rubbing Shadow
Optical issue, thus shading strip can design narrower along the width of first direction in black matrix pattern 202, and then can effectively mention
High aperture.
