Abstract: The embodiments of the present disclosure provide a backlight module. A first light-emitting diode and a second light-emitting diode are alternately arranged along a first direction and/or a second direction. The first light-emitting diode is for shining a first light-emitting area. The second light-emitting diode is for shining a second light-emitting area. An extension direction of the first light-emitting area intersects an extension direction of the second light-emitting area. A light-emitting area complementation effect is achieved, and a light mixing effect and a uniformity of light emission are further improved.
