Abstract

PURPOSE: To improve total ray transmittance and diffusivity by dispersing spherical particles of a solid silicone resin having a prescribed diameter into a transparent resin plate so that said particles exist therein.
CONSTITUTION: The silicone resin in which the org. group is directly coupled to a silicon atom, the remaining bonds are directly coupled to oxygen and the silicon atom and oxygen are made into a polymer by the repeating siloxane bonds is used. The silicone resin has the average particle size in a preferably 0.3W5μ, more preferably 0.5W3μ range. The diffusion plate of high transmission and high diffusion is obtd. at a relatively low concn. of about 1% mixing ratio of the spherical particles of the silicone with the transparent resin if the plate is as relatively thick as 1W3mm. About 20% mixing ratio is needed if the plate is as thin about 100μW200μ. The increasing of the total ray transmittance and the decreasing of the parallel ray transmittance are thereby simultaneously attained with good balance.
