Abstract
The present application provides a backlight module and a liquid crystal display device; the backlight module is provided with a light control member between a light emitting chip and a color conversion film, and the light to be emitted to outside of the edge region of the backlight module is converged to the edge region of the backlight module, thereby improving the luminance of the edge region of the backlight module, avoiding the problem that the edge of the backlight module is darkened during display, and since the light will not be directly emitted to outside of the edge of the backlight module, the problem that the edge of the backlight module is bluish is alleviated.
