PURPOSE: A light emitting diode display device is provided to improve light supply efficiency by effectively collecting light which is emitted from a LED. CONSTITUTION: A light diffuser(10) arranges light diffusing boards(12) in a matrix form and uniformly emits light which is emitted form a LED(32). An LED housing unit(20) compartmentalizes a boundary between neighboring LEDs and is composed of a plurality of LED housings(22). A printed circuit board(30) mounts a plurality of LEDs in a matrix form. A support panel(40) stores the PCB and the LED housing unit. |
