Abstract
The present invention provides a backlight module and liquid crystal display device. The backlight module includes diffuser plate, substrate, fluorescent layer and light-emitting chip. The fluorescent layer is disposed on a light-entering surface of diffuser plate, and the fluorescent layer includes quantum dot (QD). The light-emitting chip is disposed on the substrate and the light-emitting chip is between substrate and fluorescent layer for irradiating on the fluorescent layer to excite the quantum dots to emit light to form white backlight source. The present invention uses quantum dots to effectively increase luminance, color saturation and avoid chroma offset. The quantum dots can emit uniform light and reduce thickness of the backlight module.
