Abstract

Disclosed are a backlight module and a display device. The backlight module includes a back cover including an accommodation space in which a reflector, a light component, and a diffuser plate are placed in that order, wherein the light component includes a plurality of first Light Emitting Device (LED) devices and a plurality of second LED devices, wherein the second LED devices emit light at a smaller angle than the angle at which the first LED devices emit light, the first LED devices are arranged annularly and opposite in position to the periphery of the diffuser plate, and the second LED devices are located so that they are surrounded by the first LED devices. Since the first LED devices emit light at a larger angle, more light rays thereof will be incident on the edges of the diffuser plate to thereby improve effectively the phenomenon of dark strips at the edges of a picture of the backlight module; and since the second LED devices emit light at a relatively small angle, the light rays thereof can be incident on the diffuser plate while being more concentrated to thereby improve effectively the phenomena of low brightness, shadowiness, etc., of the picture of the backlight module.
