Zusammenfassung:PROBLEM TO BE SOLVED: To provide an optical sheet which is small in a coefficient of linear expansion, is excellent in optical characteristics, and is substitutable to glass applicable to a substrate for a liquid crystal display element inclusive of an active matrix type, an organic EL display element substrate, a substrate for color filters, a substrate for touch panels, a solar cell substrate, etc. SOLUTION: The optical sheet is composed of a transparent resin (a) and a glass filler (b), in which the modulus of elasticity at 100°C of the transparent resin (a) is ≤0.5 GPa. The glass transition temperature of the transparent resin (a) is desirably ≤100°C. COPYRIGHT: (C)2004,JPO&NCIPI
