COMPOSITION FOR OPTICAL MATERIAL, OPTICAL MATERIAL, METHOD FOR PRODUCING THE SAME, AND LIQUID CRYSTAL DISPLAY AND LIGHT-EMITTING DIODE EACH USING THE OPTICAL MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a composition for an optical material which has high heat resistance, low birefringence, low photoelastic coefficient, high optical transparency and toughness, to provide such an optical material, to provide a method for producing the optical material, and to provide a liquid crystal display and a light-emitting diode each using the optical material. SOLUTION: This composition for optical material essentially comprises (A) an organic compound having in one molecule at least two carbon-carbon double bonds reactive to SiH group, (B) a silicon compound having in one molecule at least two SiH groups, (C) a hydrosilylating catalyst and (D) a granular filler.
