OPTICAL SHEET, BACKLIGHT UNIT USING SAME, AND DISPLAY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an optical sheet that can prevent itself from curving and peeling-off due to its thermal deformation even if a liquid crystal display device is continuously used for long period of time; a backlight unit using the same; and a display apparatus. SOLUTION: The optical sheet for display includes: a light-diffusion layer that diffuses light emitted from the display; and at least one lens sheet that is provided on an emission surface side of the light-diffusion layer and that controls the light emitted from the display. The optical sheet for display has a support element for fixing the side face of the light-diffusion layer and lens sheet. The backlight unit using the optical sheet and the display apparatus are also provided. COPYRIGHT: (C)2009,JPO&INPIT
