Abstract:
A sealant composition for a plastic liquid crystal display cell is composed of a two-component epoxy resin composition of a base resin liquid and a curing agent liquid, wherein the base resin is a liquid epoxy resin having from 1.7 to 6 in weight average of epoxy groups in one molecule and an ionic conductivity of 2 mS/m or less; and the curing agent has an ionic conductivity of 0.6 mS/m or less. The sealant composition facilitates the fabrication of plastic liquid crystal displays having enhanced durability and sealant properties, particularly in high temperature and high humidity environments.
