BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A backlight module and a liquid crystal display device. The backlight module comprises a refraction structure (22). The refraction structure (22) comprises a first refractive surface (221) and a second refractive surface (222). The first refractive surface (221) and the second refractive surface (222) respectively are arranged at a first inclination angle and a second inclination angle. The light emitted towards the first refractive surface (221) by a light source (10) corresponding to the refraction structure (22) is refracted by the first refractive surface (221) and then passes through the refraction structure (22). The light emitted towards the second refractive surface (222) by the light source (10) corresponding to the refraction structure (22) is refracted by the second refractive surfaces and then passes through the refraction structure (22).
