Problems solved by technology

[0005] When a normally black mode liquid crystal display is turned on for a long time or a high-temperature and high-humidity trust test is performed, due to the entry of oxygen, etc., more active substances 20 are produced at the four corners of the liquid crystal region, disturbing the arrangement of the liquid crystal 10 at this position, The rotation is not in place or does not rotate, so that the light cannot pass through, and the corners are blackened.

Abstract

The embodiment of the invention provides a frame sealing glue and a preparation method thereof, a liquid crystal display panel and a preparation method thereof, and relates to the technical field of display. The invention can reduce the active matter content in the liquid crystal zone and further improve the phenomenon of black corner. The frame sealing glue comprises a main glue material, and further comprises an ion absorbent dispersed in the main glue material.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a frame sealant and a preparation method thereof, a liquid crystal display panel and a preparation method thereof. Background technique [0002] During the synthesis process of liquid crystal monomers, active substances are likely to be generated under ultraviolet (ultraviolet, UV) irradiation, high temperature action, and high humidity environment. [0003] At present, in the manufacturing process of the liquid crystal display panel, after the array substrate and the box-aligning substrate are box-boxed, the sealing glue needs to be subjected to thermal polymerization treatment and UV polymerization treatment. However, since the liquid crystal monomer is more likely to produce active substances under the action of UV light and high temperature, when the sealant is subjected to thermal polymerization treatment and UV polymerization treatment, based on the production of active su...
