Disclosed is an edge-lit backlight module having a rectangular back panel with a reflective microstructure, and a first light portion with an inclined plane or a camber is provided for reflecting lights emitted from a plurality of LEDs and with a relatively smaller normal included angle, and a second light portion is provided for reflecting a light with a slightly greater included angle, and a third light portion is provided for reflecting the light with the greatest included angle to guide lights of different intensities to different paths and project the lights to every position of a front panel, so as to achieve a light extraction efficiency with a uniform distribution of luminous intensity of an LED light source. |
