Problems solved by technology

However, as mentioned above, the curing rate of the sealant 20 is difficult to reach 100%; The orientation is disordered, at least the orientation of the liquid crystal molecules 10 close to the sealant 20 is disordered, such as Figure 1b shown
When the alignment of liquid crystal molecules is disordered, the liquid crystal display panel will produce light leakage.

Abstract

The invention provides frame seal adhesive, a manufacturing method of an LCD (Liquid Crystal Display) panel and the LCD panel. The frame seal adhesive comprises a body and a component for inducing liquid crystal molecular orientation, wherein the component for inducing the liquid crystal molecular orientation is mixed with the body.

Description

technical field [0001] Embodiments of the present invention relate to a frame sealing glue, a manufacturing method of a liquid crystal display panel, and a display panel. Background technique [0002] A liquid crystal display panel generally includes an array substrate, an opposite substrate, and a liquid crystal layer disposed between the array substrate and the opposite substrate. The preparation method of the liquid crystal display panel usually includes: forming a sealant between the array substrate and the opposite substrate; and curing the sealant to bond the array substrate and the opposite substrate together and seal the liquid crystal layer between the substrates. However, the curing rate of the sealant is difficult to reach 100%. [0003] When displaying on a liquid crystal display panel, the liquid crystal molecules 10 in the liquid crystal layer will be regularly aligned along a specific direction, such as Figure 1a shown. However, as mentioned above, the cur...
