摘要:
A light control film comprising a downward prism sheet and a light diffusing sheet having a rough surface as a surface facing the downward prism sheet, which solves the problem of mutual scratching of constituent members. The light control sheet of the present invention comprises at least a light diffusing film and a prism sheet disposed as a laminate. One surface of the light diffusing film is a light diffusing surface, and the other surface is a rough surface. One surface of the prism sheet is a prism surface, and the other surface is a smooth surface. The smooth surface is constituted by a smooth layer containing at least a comb polymer. By this configuration, the facing surfaces comes to be hardly scratched, in spite of the structure in which the rough surface of the light diffusing film and the smooth surface of the prism sheet are disposed to face each other.
