Bezel Sealant, Liquid Crystal Display Panel and Liquid Crystal Display

摘要

The present invention provides a bezel sealant for use in a polymer stabilized vertical alignment liquid crystal display. The bezel sealant includes at least the following compositions: epoxy resin 20-60% by weight, curing agent 5-50% by weight, methacrylate resin or acrylate resin 20-60% by weight, photoinitiator 0.1-1% by weight, filler 5-35% by weight, and silane coupling agent 0.05-5% by weight. The molecular weight of the methacrylate resin or the acrylate resin is greater than or equal to 500. According to the embodiment of the present invention, the dissolution of the methacrylate resin or acrylate resin in the bezel sealant by the liquid crystal medium is prevented to avoid the over-sized bumps formed in the periphery of the bezel. Light leakage phenomenon in the periphery of the bezel is decreased to increase product yield rate.
