LIGHT COLLECTING SHEET-LAMINATED LIGHT DIFFUSER PLATE

摘要

The present invention provides a light collecting sheet-laminated light diffuser plate which can diffusely transmit transmission light (L) with sufficient luminance without causing rubbing of a light diffuser plate (2) and a light collecting sheet (4) against each other. The light collecting sheet-laminated light diffuser plate (1) of the present invention comprises a light diffuser plate (2), a light collecting sheet (4) and an adhesive layer (3), the light collecting sheet being laminated on one side (2a) of the light diffuser plate via the adhesive layer, wherein the one side (2a) is provided with unevenness, and the light collecting sheet (4) is laminated on the one side (2a) so that the adhesive layer (3) is not contacted with the bottom (2a1) of the unevenness.
