Problems solved by technology

However, in the area where the alignment liquid 104B is close to the bump 102B, it may flow to the area of ​​the sealant 106B due to excess alignment liquid 104B
Moreover, since the level difference of the formed grooves or bumps is relatively small, the alignment liquid can easily overflow the grooves or bumps and cause the design to fail.

Abstract

The invention provides a liquid crystal panel, which comprises an upper substrate, a lower substrate and frame glue, wherein the lower substrate comprises a display area, a non-display area, a first limiting component and a second limiting component; the non-display area is adjacent to the display area; and the frame glue is arranged on the non-display area; the first limiting component is located at edge of the non-display area; the second limiting component is located between the display area and the first limiting component. By virtue of combination of the first limiting component and the second limiting component, when an alignment film is coated on the lower substrate, the alignment film is not expanded to the non-display area.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal panels, in particular to a method for manufacturing a liquid crystal panel with a uniform alignment film. 【Background technique】 [0002] The liquid crystal panel is an important component of the liquid crystal display, and the liquid crystal panel mainly includes an array substrate, a color mold substrate, and a liquid crystal enclosed between the array substrate and the color mold substrate. The liquid crystal is aligned through the alignment layer coated on the array substrate and the color mold substrate to control the alignment direction of the liquid crystal molecules and provide the pre-tilt angle required by the liquid crystal display structure to achieve the display effect of the liquid crystal panel. The commonly used alignment film is polyimide (PI) material, which has high heat resistance, chemical solvent resistance, good radiation and electrical insulation properties, and th...
