Liquid crystal coating method and display panel manufacturing method

Abstract

The embodiment of the invention discloses a liquid crystal coating method and a display panel manufacturing method and relates to the technical field of display. Orientation arrangement of liquid crystal molecules are achieved while liquid crystals are coated, so that orientation films and the instilled liquid crystal are prevented from being rubbed. The liquid crystal coating method comprises the steps that the orientation films are formed on a light-transmitting substrate, and the orientation film molecules are arranged in the orientation films in an orientation mode; a slit shower nozzle is used for coating the liquid crystal materials on the light-transmitting substrate with the formed orientation films, and the liquid crystal materials comprise the liquid crystal molecules and light-induced reaction groups; while the liquid crystal materials are coated, first ultraviolet light is used for irradiating the liquid crystal materials.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal coating method. Background technique [0002] The display panel mainly includes an array substrate, a color filter substrate, and a liquid crystal molecule layer between the array substrate and the color filter substrate. In order to make the display panel have uniform brightness and high contrast, the liquid crystal molecules in the liquid crystal molecule layer are usually arranged along a certain direction. [0003] At present, the alignment of liquid crystal molecules is mainly achieved through the following processes: first, a layer of alignment film is formed on the array substrate; then, the alignment film is rubbed to form multiple parallel grooves on the surface of the alignment film; The liquid crystal is dripped on the substrate, so that the liquid crystal molecules are aligned along the grooves on the alignment film. [0004] The inventors have fou...

AI Technical Summary

Problems solved by technology

[0004] The inventors have found that various defects are likely to occur during the process of rubbing the alignment film and instilling liquid crystals, for example, particles are generated on the surface of the alignment film during the rubbing process, and there are burrs in the grooves formed by friction, etc.; the liquid crystal molecules cannot be filled with the display panel during the infusion process. The corner area, the liquid crystal molecules and the sealing glue contact prematurely to cause liquid crystal pollution, etc.

These defects will have a negative impact on the display effect of the display panel
