Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical material substituting a glass, having a low thermal expansion coefficient, exhibiting a high light transmittance, having high reliability, and suitably usable for a substrate (especially of an active matrix type) for a display element such as a liquid crystal display element and an organic EL element, a substrate for a color filter, a substrate for a touch panel, a substrate for a solar battery or the like. SOLUTION: The transparent compounded composition comprises (a) a transparent resin and (b) a glass filler in which the content of an alkali metal is ≤1%. The refraction index of the glass filler (b) is preferably 1.45-1.55. A composition of 50-60% SiO2, 10-18% Al2O3, 11.0-25.0% B2O3, 1.0-6.0% MgO, 1.0-10.0 CaO, 0.5-5% TiO2and 0-1% (LiO2+Na2O+K2O) is cited as a preferable example. COPYRIGHT: (C)2004,JPO&NCIPI
