LIGHT CONTROL SHEET AND SURFACE LIGHT SOURCE USING IT

摘要

A light control film provided with a prism sheet facing down, and a light diffusing sheet having an uneven surface facing the prism sheet is provided to prevent the constituting members from scratching each other. The light control sheet includes at least the light diffusing film and the prism sheet arranged one on the other. One surface of the light diffusing film is a light diffusing surface, and the other surface is the uneven surface. One surface of the prism sheet is a prism surface, and the other surface is a smooth surface. The smooth surface is composed of a smooth layer containing at least a comb-shaped polymer. Thus, even with a structure where the uneven surface of the light diffusing film and the smooth surface of the prism sheet are arranged to face each other, scratches are not easily generated on the facing surfaces.
