Liquid crystal display panel and preparation method thereof

Abstract

The invention provides a liquid crystal display panel and a preparation method thereof. The liquid crystal display panel comprises an array substrate, a passivation layer, a planarization layer, a BPSmaterial layer and a first orientation layer, wherein the passivation layer, the planarization layer, the BPS material layer and the first orientation layer are sequentially stacked on the array substrate; the projection of the first orientation layer on the BPS material layer does not exceed the area of the BPS material layer; and multiple grooves are formed in the BPS material layer and distributed along the inner side of the edge of the BPS material layer, and a frame adhesive is formed on the BPS material layer, wherein the frame adhesive and the first orientation layer are located at thetwo sides of the multiple grooves respectively. According to the liquid crystal display panel and the preparation method thereof, flowing of the frame adhesive and the first orientation layer can bestopped without preparing a stop wall on the array substrate, and the situation that the frame adhesive and the first orientation layer on the array substrate exceed specifications in preparation is avoided.

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] BPS (Black photo spacer, black photoresist spacer material) technology is a technology in LCD (Liquid Crystal Display, liquid crystal display) technology that combines two processes of BM (black matrix) and PS (gap control) into one process. This technology can perform BPS process on the color filter substrate side or array substrate side, perform BPS process on the array substrate side, and then use COA (Color on Array, integrating color filter substrate and array substrate together) technology to integrate the array substrate and color filter The substrate is assembled into a box, and the corresponding color filter substrate side has only one front ITO (indium tin oxide) electrode layer, and there are no other film layers. This design can be applied to the situation where the flat d...

AI Technical Summary

Problems solved by technology

Since there is no patterned film layer on the side of the color filter substrate, there is no design for retaining walls

The BPS material layer on the side of the array substrate acts as a light-shielding function, so it is impossible to make a raised barrier, and it cannot be realized even if a color resist is used as a barrier, because the planarization layer and the BPS material layer are both organic layers, and both It is very thick, so the bumps of the color resistance will be flattened by the two organic layers, and cannot function as a barrier
