Title:
BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/149406
Kind Code:
A1
Abstract:
A backlight module and a liquid crystal display device. The back light module comprises a first light-emitting component (23) and at least one second light-emitting component (24). The first light-emitting component (23) is arranged outside of a light guide area between an optical film (21) and a reflective plate (22); the at least one second light-emitting component (24) is arranged within the light guide area. The at least one second light-emitting component (24) comprises a curved reflector (243). The curved reflector (243) is faced towards the first light-emitting component (23) and is for use in reflecting to the optical film (21) a light emitted towards the at least one second light-emitting component (24). Hence, even when the size of the liquid crystal display device is increased, the need for increasing the thickness of the backlight module is obviated, while the backlight module is ensured to provide great light-emitting effects.
