Liquid crystal display device and backlight module thereof

Abstract

The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device regards an organic electroluminescent device as a backlight module thereof. The liquid crystal display device comprises at least one first organic electroluminescent device for emitting a red light source, at least one second organic electroluminescent device for emitting a green light source, and at least one third organic electroluminescent device for emitting a blue light source disposed on a liquid crystal panel to define a plurality of pixels within which. Thus, the liquid crystal display device can achieve the purpose of full color display without disposing a color filter in which.
