Abstract
The present invention provides a liquid crystal sealing composition and a liquid crystal display panel excellent in adhesion, moisture permeation resistance and heat resistance and superior for use in a sheet press heating bonding system. The liquid crystal sealing composition comprises (1) an alkoxysilyl group-containing modified epoxy resin obtained by de-alcohol condensation reaction of (a) an epoxy resin having at least one hydroxyl group in one molecule and (b) an alkoxysilyl group-containing compound, (2) a heat latent epoxy curing agent, (3) a filler having an average particle diameter of 0.1 to 10 μm, and if necessary (4) an epoxy resin having at least 1.2 epoxy groups on average in one molecule, (5) an aprotic solvent having a boiling point in the range of 140 to 220° C., compatible with epoxy resin and inert to an epoxy group, and (6) other additives.
