<p><P>PROBLEM TO BE SOLVED: To provide a plastic sheet that has light-scattering performance for attaining light confinement effect, shows high degree of freedom of surface shape and is excellent in thermal dimensional stability. <P>SOLUTION: The plastic sheet comprises a transparent resin (a) and a glass filler (b) and has light transmission of≥80%, haze of 15-95% and average coefficient of linear expansion at 30-150°C of≤40 ppm. The transparent resin (a) preferably comprises a cured product of a resin composition essentially comprising an epoxy resin, and the difference in refractive index between the transparent resin (a) and the glass filler (b) is≥0.01. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
