Problems solved by technology

[0003] However, while the area of ​​the dark pattern is reduced as much as possible, it will increase the transmittance variation of the display panel at different angles in the horizontal rotation viewing angle.
refer to figure 1 , when the existing display panel is rotated horizontally, it will be found that the transmittance of the horizontally rotated viewing angle of the display panel has a change of about 14% (114% to 100%) when viewed from a 45-degree viewing angle. Too obvious, resulting in poor visual experience

Abstract

A display panel and a manufacture method are provided. The display panel includes a TFT substrate (100) and a photo-alignment layer. The TFT substrate includes a plurality of pixel units, wherein each pixel unit includes a plurality of sub-pixels. The photo-alignment layer is located on the pixel units, and has at least two different aligning directions corresponding to each sub-pixel. When light passes through each sub-pixel, the display panel shows a dark line pattern. The dark line pattern includes a major line and a minor line. The major line is located on the boundary between the two different aligning directions in the photo-alignment layer, and extends along a first direction, wherein the major line has a major line width. The minor line is connected to the major line, and extends along a second direction, wherein the minor line has a minor line width, and the major line width is greater than the minor line width.

Description

technical field [0001] The invention relates to a display panel, in particular to a display panel with a photo-alignment layer. Background technique [0002] Existing display panels include thin film transistor substrates, photo-alignment layers, liquid crystal layers and other elements. The existing photo-alignment layer manufacturing process first forms an alignment layer on the thin-film transistor substrate, and then uses alignment masks aligned in different directions to cover different parts of the thin-film transistor substrate with the alignment layer, and then passes through the exposure step. Photo-alignment layers with different orientations are formed on the TFT substrate. In the prior art, when a light passes through each sub-pixel of the TFT substrate having photo-alignment layers aligned in different directions, the display panel will display a dark pattern. In order to increase the aperture ratio of the display panel, the existing concept tends to reduce th...
