Description

Liquid crystal composition containing novel dibenzothiophene polymerizable compound and application thereof

Technical Field

The invention relates to the technical field of liquid crystal, in particular to a liquid crystal composition containing a novel dibenzothiophene polymerizable compound polymerizable monomer.

Background

Negative liquid crystals, which were proposed at the beginning of the 80's last century, are mainly used in the VA mode, which has very excellent contrast performance, but has significant viewing angle problems and response time problems, and in order to solve the viewing angle problems, display technologies such as MVA, PVA, CPA, etc., which are essentially to solve the viewing angle problems using multi-domains and achieve good effects, have been proposed. However, the display industry has been plagued by problems of increased difficulty and response time in the art, until PSVA (polymer stabilized vertical alignment) technology has been proposed, which uses polymers to achieve multi-domain and pretilt angle control to achieve fast response and wide viewing angle liquid crystal displays.

The existence of the polymerizable monomer and the liquid crystal causes the voltage holding ratio of the liquid crystal to be reduced, so a working procedure needs to be added in the production process of the liquid crystal display to fully react the residual polymerizable monomer, and in order to ensure the full reaction, the time is usually longer, so the process time is prolonged, and the productivity is reduced; on the other hand, since the glass substrate needs to be exposed for a period of time after the completion of the preceding process, the surface layer of the panel is contaminated by the pollution source in the environment, which results in the degradation of the quality of the liquid crystal display.

The invention aims to provide a liquid crystal material capable of reacting quickly, shorten the polymerization time of polymerizable monomers and improve the production capacity of liquid crystal displays; the interval time of the working procedures in the production process of the liquid crystal display is shortened, and the quality of the liquid crystal display is improved.
