TECHNOLOGY FOCUS - POLYMERS - Preferred Sheet: The particle dispersed-type resin sheet further has a gas barrier layer (2) and a hard-coat layer (3) consisting of urethane type resin.Preferred Layer: The epoxy resin layer (1) further contains a cycloaliphatic resin.Preferred Properties: The ratio of epoxy resin, which has bisphenol-S type structure, and inorganic oxide in the epoxy resin layer are 3-60 wt.% and 10-70 vol.%, respectively. The average particle diameter of the inorganic oxide is 1-100 microns. The light transmittance of the resin sheet at 550 nm is 88% or more. The linear expansion coefficient of the resin sheet at 25-160degreesC is 5.00E-5/degreesC. The glass transition temperature of the resin sheet is 170degreesC or more. The fracture intensity of the resin sheet is determined by interposing the resin sheet, which has damage of depth 1 microns on the reverse side of paper of 2000, between pure flat plate and flat plate having hole of 20 mm(phi), installing in a horizontal direction, and fixing the four corners. The fracture intensity, when applied with a load at central portion of exposed area of 20 mm(phi) by a bearing bar, which has globular form front-end of 10 mm(phi), from the front vertical direction, is more than 35N. EXAMPLE - Bisphenol-S type epoxy resin (in weight parts) (40) of formula (1), 3,4-epoxy cyclohexyl methyl-3,4-epoxy cyclohexane carboxylate (17.2) of formula (2), methyl hexahydrophthalic anhydrides (41.9) of formula (3), and tetra-n-butyl phosphonium-o-o-diethyl phosphoro dithionate (1) of formula (4), were stir-mixed to obtain epoxy-resin liquid. The obtained epoxy resin liquid (840) and glass beads (340) of average particle diameter 30 microns, were mixed to obtain inorganic oxide-containing epoxy resin liquid. The obtained inorganic oxide-containing epoxy resin liquid was applied at 0.3 m/minute on gas barrier layer, and cured to obtain inorganic oxide-containing epoxy resin layer of thickness 300 microns. The obtained inorganic oxide-containing epoxy resin layer had fracture intensity of 60 N, glass transition temperature of 190degreesC, dimensional change rate of 0.03%, linear expansion coefficient of 4x10-5/degreesC and light transmittance of 89%.
