Abstract

The invention relates to a backlight module and a liquid crystal display device using the backlight module. The backlight module includes multiple light sources and a light mixing plate. The plurality of light sources can respectively emit light of different colors. The light mixing plate is adjacent to the plurality of light sources, and has a plurality of groove structures on a side adjacent to the plurality of light sources. The backlight module and the liquid crystal display device using the light mixing plate are thin in thickness and small in volume under the condition of meeting light mixing requirements.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display device using the backlight module. Background technique [0002] Please refer to figure 1 , is a partial cross-sectional schematic diagram of a prior art liquid crystal display device. The liquid crystal display device 2 includes a liquid crystal panel 24 , a backlight module 20 and a plastic frame 21 . The backlight module 20 is adjacent to the liquid crystal panel 24 and provides planar light for the liquid crystal panel 24 . The plastic frame 21 accommodates the backlight module 20 and supports the liquid crystal panel 24 . [0003] The plastic frame 21 is a rectangular frame without a cover, which includes a bottom plate 211 and a plurality of side walls 212 , the bottom plate 211 and the side walls 212 are vertically connected to form a receiving space. [0004] The backlight module 20 is a direct type backlight module, which includes a plurality of red, green, and blue l...
