Problems solved by technology

[0006] Since the methacrylate monomer in the frame glue has a very similar structure to the polymerizable monomer monomer in the liquid crystal, part of the methacrylate monomer in the frame glue may be dissolved by the liquid crystal during the panel manufacturing process. Participating in the polymerization reaction under ultraviolet light irradiation, it is easy to form large bumps around the panel near the frame adhesive, resulting in bright spots visible in the dark state, causing light leakage around the PSVA panel

Embodiment Construction

[0033] like figure 1 As shown, a schematic diagram of a polymer-stabilized vertical alignment liquid crystal display panel of the present invention is shown, the liquid crystal display panel includes: a first substrate 1, a second substrate 2, a liquid crystal layer 3 sandwiched between the two substrates, and The frame adhesive material 4 that seals the liquid crystal in the two substrates. The ITO electrode 5 is further provided on the opposite side of the first substrate 1 and the second substrate 2 . The liquid crystal layer contains at least liquid crystal molecules 30 and a polymerizable monomer. When the ITO electrode 5 is connected, the polymerizable monomer forms a bump (bump) 31 on the first substrate 1 and the second substrate 2, wherein , the molecular weight of the polymerizable monomer in the liquid crystal layer is less than 500.

[0034] Wherein, the frame adhesive material 4 at least contains the following components:

[0035] Epoxy resin, 20%~60% by weight...

Abstract

The invention provides a frame plastic material used for liquid crystal displayer with polymer stabilized vertical alignment. The frame plastic material at least contains the following constituents by weight percent: 20%-60% of epoxy resin, 5%-50% of a hardening agent, 20%-60% of methacrylate resin or acrylate resin, 0.1%-1% of a photoinitiator, 5%-35% of filler and 0.05%-5% of a silane coupling agent, wherein the molecular weight of the methacrylate resin or the acrylate resin is not less than 500. The invention correspondingly provides a liquid crystal display panel and a liquid crystal displayer which use the frame plastic material. By the implementation of the frame plastic material, the liquid crystal panel and the liquid crystal displayer, the methacrylate resin or the acrylate resin can be prevented from being dissolved out by a liquid crystal medium, sequentially, the formation of oversize bump particles near the frame is avoided, and the light leakage phenomenon near the frame is reduced.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a frame adhesive material, a liquid crystal display panel and a corresponding liquid crystal display. Background technique [0002] The liquid crystal used in TN (Twisted nematic, twisted nematic) or STN (Super twisted nematic, super twisted nematic) liquid crystal displays is a positive liquid crystal, and the long axis of the liquid crystal molecules is parallel to the substrate surface when no power is applied. The alignment direction of the liquid crystal molecules on the surface of the substrate is determined by the rubbing direction of the alignment layer (the material is usually Polyimide). In a continuous twisted arrangement. When a voltage is applied, the long axes of the liquid crystal molecules will tend to align in the direction of the electric field. The disadvantage of TN / STN type liquid crystal display is that the viewing angle is small, and the brightness dif...
