LAMINATE SHEET, LIQUID CRYSTAL DISPLAY MODULE, BACKLIGHT UNIT, AND METHOD FOR MANUFACTURING LAMINATE SHEET

摘要

The purpose of the present invention is to provide a laminate sheet capable of minimizing luminance unevenness caused by the shape of other optical members arranged on the rear surface while suppressing sparkles caused by the interference with the pixel pitch in a liquid crystal panel. The laminate sheet according to the present invention includes an intermediate layer, a first matte layer laminated onto the front surface of the intermediate layer, and a second matte layer laminated onto the rear surface of the intermediate layer. The 60° glossiness on the rear surface of the second matte layer is 3/2 or more and 10 or less of the 60° glossiness on the front surface of the first matte layer. The 60° glossiness on the front surface of the first matte layer is preferably 5 or more and 20 or less. The 60° glossiness on the rear surface of the second matte layer is preferably 30 or more and 80 or less. The arithmetic average roughness (Ra) on the front surface of the first matte layer is preferably 0.5 μm or more and 1 μm or less. The arithmetic average roughness (Ra) on the rear surface of the second matte layer is preferably 1/5 or more and 9/10 or less of the arithmetic average roughness (Ra) on the front surface of the first matte layer.
