Abstract

The present invention provides a liquid crystal display panel and a preparation method. The method includes: providing a first substrate and a second substrate, and combining the first substrate and the second substrate; filling liquid crystal between the first substrate and the second substrate; A mixture of a polymeric group, a second polymeric group and a dichroic dye; control the polymerization of the first polymeric group and part of the dichroic dye on one side of the first substrate, and control the polymerization of the second polymeric group and the other part of the dichroic dye Polymerized on the second substrate side, the orientation direction of the dichroic dye in the first polymer group is perpendicular to the orientation direction in the second polymer group; for the first polymer group, the second polymer group and Dichroic dye curing treatment, sequentially forming a stacked first alignment layer and a first polarizing layer on the side of the first substrate close to the second substrate, and sequentially forming a stacked second alignment layer on the side of the second substrate close to the first substrate layer and a second polarizing layer. The present invention omits the coating process and only needs to be carried out at low temperature.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a preparation method thereof. Background technique [0002] After the liquid crystal display panel is filled with liquid crystals, it is necessary to align the liquid crystals. The existing alignment process is to coat the polyimide liquid in the liquid crystal display panel, and then go through pre-baking, ultraviolet light irradiation, high-temperature curing and other processes to obtain alignment. The film is aligned, and the production process is relatively complicated, and the high-temperature process is not suitable for quantum dots and other products that need to be produced under low-temperature processes. [0003] Therefore, the existing liquid crystal display panel has the technical problems of high alignment process temperature and complex process, which need to be improved. Contents of the invention [0004] The invention provid...
