Embodiment 1

[0038] Please refer to figure 1 , figure 1 It is a schematic diagram of a liquid crystal display panel according to an embodiment of the present invention. The liquid crystal display panel 100 of this embodiment includes a first substrate 110, a second substrate 120, a liquid crystal layer 130, a pair of opposite electrodes 140, a pixel array structure 150, at least one alignment layer 160 and at least one polymer layer 170. The liquid crystal layer 130 is disposed between the first substrate 110 and the second substrate 120 . The opposite electrode 140 is disposed between the liquid crystal layer 130 and the first substrate 110 . In addition, the pixel array structure 150 is disposed between the liquid crystal layer 130 and the second substrate 120 . In addition, the alignment layer 160 (or called the bottom alignment layer) is disposed between the opposite electrode 140 and the liquid crystal layer 130 , and between the pixel array structure 150 and the liquid crystal la...

Embodiment 2

[0068] Please refer to Figure 2A Firstly, the liquid crystal molecules 132, the polymerized monomer molecules 172' and the polymethyl methacrylate 174 are mixed and arranged between the first substrate 110 and the second substrate 120. Here, the mixture of liquid crystal molecules 132, polymerized monomer molecules 172' and polymethyl methacrylate 174 is called liquid crystal mixture 130', for example.

[0069] Next, please also refer to the Figure 2A and Figure 2B , a specific electric field is applied between the first substrate 110 and the second substrate 120 . At the same time, under the action of the above-mentioned electric field, the polymerized monomer molecules 172' are polymerized to form polymers 172. After the polymer 172 is cured, the polymer layer 170 will be formed on the first substrate 110 and the second substrate 120 on both sides of the liquid crystal layer 130 . At this point, the manufacture of the liquid crystal display panel 100 is completed.

The pixel array structure is arranged between the liquid crystal layer and the second substrate. The alignment layer is arranged between the opposite electrode and the liquid crystal layer, and between the pixel array structure and the liquid crystal layer. The polymer layer is arranged between the alignment layer and the liquid crystal layer, wherein the material of the polymer layer includes a plurality of macromolecular monomers and polymethyl methacrylate, and the content of polymethyl methacrylate in the polymer layer is greater than 1ppm , and less than 15000ppm.

Description

technical field [0001] The invention provides a liquid crystal display panel, in particular relates to a liquid crystal display panel with a polymer layer that assists alignment. Background technique [0002] The manufacturing process of the liquid crystal display mainly includes the manufacture of a liquid crystal display panel (liquid crystal panel) and the assembly of a liquid crystal display module (liquid crystal module, LCM). Among them, the manufacture of the liquid crystal display panel is mainly to seal the liquid crystal between the color filter substrate and the pixel array substrate. In order to make the liquid crystal molecules have a specific tilt angle and arrangement to achieve a wide viewing angle display effect, the liquid crystal display panel needs to be designed with an alignment structure. [0003] Based on the above, common alignment structures include alignment protrusions and alignment slits disposed on the electrodes. The arrangement of the alignm...
