Problems solved by technology

[0004] At present, PSVA technology has been applied to the alignment process of fast-response liquid crystals. However, due to the fact that there are more carbon-carbon double bonds in fast-response liquid crystals, and the current photo-alignment process uses ultraviolet light with a preset wavelength, the preset wavelength Ultraviolet light is easily absorbed by carbon-carbon double bonds, resulting in insufficient ultraviolet light for the alignment process, which in turn reduces the photoalignment efficiency

Abstract

The invention discloses a reaction monomer and a preparation method thereof, and a manufacturing method of a display panel. The structural general formula of the reaction monomer is shown in the specification. In the formula , X is S, Se or Te, and R1 and R2 are both substituted or unsubstituted aryl groups. The reaction monomer provided by the invention has a lower energy band and can absorb light with longer wavelength, and the energy band of the reaction monomer can be controlled by replacing heteroatoms so as to absorb light with different wavelengths; and thus, the reaction monomer provided by the invention can complete an alignment process under light sources with different wavelengths, so the wavelength selection range of a light source in an optical alignment process is expanded, and the yield of the optical alignment process is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a reactive monomer, a preparation method thereof, and a method for manufacturing a display panel. Background technique [0002] With the continuous development of display technology, various types of displays have emerged. Current flat panel displays mainly include Liquid Crystal Display (LCD), Plasma Display (PDP), Organic Light Emitting Diode Display (OLED) and the like. Among them, liquid crystal displays have been widely used in various fields due to their advantages of low weight, small volume, and low energy consumption. [0003] Polymer Sustained Vertical Alignment (PSVA) mode liquid crystal panels have been widely used in liquid crystal displays. In PSVA display technology or other display technologies that require optical alignment, a voltage is applied across the liquid crystal cell and ultraviolet light Under the excitation of the reaction monomer, the polymerizatio...
