Embodiment Construction

[0030] In actual production, the staff found that if figure 1 as shown, figure 1 The first substrate 1 is coated with an auxiliary sealant 2 distributed in a straight line. During the subsequent etching process, the etching material is easy to penetrate into the box, causing pollution to the box, corroding the panel electrodes, and reducing the product yield. .

[0031] In order to avoid the above problems, an embodiment of the present invention provides a liquid crystal panel, including a first substrate and a second substrate, the first substrate and the second substrate are oppositely arranged, and the liquid crystal panel also includes an auxiliary sealant structure ,Such as Figure 2a , 2b , 2c and 2d, the auxiliary sealant structure is arranged between the first substrate 21 and the second substrate 11 which are oppositely arranged, and the auxiliary sealant includes a structure located on the first substrate 21 or the second substrate 11 ( Figure 2a , 2b and 2c no...

Abstract

The invention discloses a liquid-crystal display panel and particularly relates to a manufacturing process of a large glass panel. The liquid-crystal display panel comprises auxiliary sealant arranged between a first substrate and a second substrate, the auxiliary sealant comprises outer auxiliary sealant and inner auxiliary sealant, the outer auxiliary sealant is arranged on the periphery of the first substrate or the second substrate, the inner auxiliary sealant is arranged in the middle of the first substrate or the second substrate, the plane of the outer auxiliary sealant is annular and is provided with at least one opening, and at least one frame of main sealant is arranged between the inner auxiliary sealant and the outer auxiliary sealant. The liquid-crystal display panel has the advantages that internal and external pressure difference is reduced in finished boxes during packaging, edge sealant and auxiliary sealant form a closed loop in the plane by means of a thinning process, pollution of the edge sealant into the boxes is avoided, procedures are reduced, and cost is reduced. In the follow-up etching process, etching materials are effectively prevented from entering the boxes to cause corrosion of panel electrodes, and production yield rate is increased.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panels, in particular to an auxiliary frame structure in the production process of a large glass liquid crystal panel, a large glass liquid crystal panel including the auxiliary frame structure and a manufacturing method thereof. Background technique [0002] In the existing large glass panel manufacturing process, the first substrate and the second substrate are involved. By coating the auxiliary sealant structure on the surface of the first substrate, and then bonding the first substrate and the second substrate, the cell (Cell) is completed. ) process, the auxiliary frame glue mainly plays a supporting role, so that the first substrate and the second substrate always maintain a certain distance. In the subsequent etching process, the etching material is likely to enter the box, pollute the box, corrode the panel electrodes, and affect the yield. Contents of the invention [0003] In v...
