Abstract

The invention discloses a self-alignment liquid crystal, and a display device and a preparation method thereof. The self-alignment liquid crystal comprises a self-alignment material, a liquid crystalmedium and a polymerizable monomer, wherein the mass ratio of the self-alignment material is 0.01 wt%-2 wt%, and the mass ratio of the polymerizable monomer is 0.01 wt%-2 wt%. The self-alignment liquid crystal has the advantages that the self-alignment liquid crystal can replace an alignment film in a liquid crystal display panel, the preparation process of the alignment film is omitted, cost is saved, and production efficiency is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a self-aligned liquid crystal, a display device and a preparation method thereof. Background technique [0002] On the CF substrate and the TFT substrate of the liquid crystal display (LCD), there is a layer of thin film material, its main function is to arrange the liquid crystal molecules in a certain direction, we call it an alignment film (commonly used polyimide (PI) material). This kind of matching film is mainly divided into friction matching type PI material and photo matching type PI material, but no matter which kind of alignment material has its own disadvantages. First of all, frictional matching is likely to cause problems such as dust particles, static residue, brush marks, etc. and reduce process yield. Although optical matching materials can avoid these problems, due to limited material properties, heat resistance and aging resistance are not good. At the same time The abilit...
