The invention discloses a backlight module. The backlight module comprises a light source array, a reflector plate module and an optical film. The light source array comprises a plurality of light sources, and light emitted by the light sources can be refracted through lens units in the light sources to obtain specific light emitting angles and uniformity. The reflector plate module comprises a plurality of reflecting units, each reflecting unit comprises a plane part, a first wall part and a corner wall part, and the reflecting units can achieve the display effect that the light source presents fewer shadows and the contrast ratio is better at different height differences. 本发明公开一种背光模块。背光模块包括光源阵列、反射片模块以及光学膜片。光源阵列包括多个光源，通过光源内部的透镜单元使得光源所发出的光线可通过透镜单元折射得到特定的出光角度和均匀度；反射片模块包括多个反射单元，每一反射单元包括平面部、第一墙部以及角落墙部，彼此以不同的高度差能达到光源呈现出较少暗影和对比率较佳的显示效果。
