PURPOSE: A lighting panel structure of a LED luminous face illuminator is provided to improve illuminance efficiency by mounting a plurality of high luminance sheets between the diffusion sheet of a laminating panel and a light guide plate. CONSTITUTION: In a lighting panel structure of a LED luminous face illuminator, a circumference frame(3) has an LED strip therein. A lighting panel(4) is supported by the support frame. High luminance sheets(8a,8b) are laminated between an acryl plate(7) and the light guide plate. The luminance sheet is arranged in a lattice. An acryl plate is formed into the acryl plate in which a diffuser is not included. Two high luminous sheets are overlapped and are built therein. |
