PURPOSE: To provide such a liquid crystal sealing material for a liquid crystal panel that shows little shrinkage during hardening and thermal expansion, has excellent adhesion property and moisture resistance and that radical polymn. is not prevented during hardening with UV rays, and to provide a liquid crystal display device using this sealing material and having good display quality and high reliability against the environment. CONSTITUTION: A liquid crystal 5 is sealed in the space between two substrates 1a, 1b each having an electrode 2a, 2b and an orienting film 3a, 3b, respectively, with a sealing material 6 to obtain a liquid crystal display device. The sealing material to adhere the two substrates and to seal the liquid crystal consists of 68wt.% bisphenol-A epoxy acrylate oligomer, 5wt.% pentaerythritol, 5wt.% ethoxydiethylene glycol acrylate, 5wt.% 2,2-dimethoxy-2phenylacetone as a photopolymn. initiator, 4wt.% modified aromatic amine-based thermosetting agent, 3wt.%γ-glycidoxypropyl trimethoxy silane, 10wt.% magnesium silicate hydrate, and 3wt.% silicon dioxide. This sealing material is hardened by irradiation of UV rays and heat.
