Liquid crystal alignment liquid

Abstract

The invention provides a liquid crystal alignment liquid which comprises at least one polymer selected from a class formed by a polyamic acid- polyamic acid polymer, a polyimide-polyamic acid polymer and a polyimide-polyimide polymer, wherein the polyimide-polyamic acid polymer is shown in the following formula.

Description

technical field The invention relates to a liquid crystal alignment liquid, and in particular to a liquid crystal alignment liquid which can improve the efficiency of a liquid crystal display element. Background technique Liquid crystal display (liquid crystal display) is a display that utilizes the photoelectric changes of liquid crystals. It has attractive advantages such as small size, light weight, low power consumption, and good display quality. Therefore, it has become the mainstream of flat-panel displays in recent years. The main manufacturing process of the liquid crystal display includes the manufacture of a liquid crystal panel (liquid crystal panel) and the assembly of a liquid crystal display module (LCM). The manufacturing method of the liquid crystal panel is mainly to seal the liquid crystal between the color filter plate as the upper substrate and the thin film transistor array substrate as the lower substrate. For liquid crystal displays, it is very impor...

Problems solved by technology

In the prior art, when a voltage is applied to the liquid crystal display element, the generated ionic charge will be absorbed by the liquid crystal alignment film, and even after the applied voltage is released, it is difficult to dissipate the ionic charge from the liquid crystal alignment film. Detachment, which will cause the problem of afterimage on the screen
