Abstract
A backlight module including a light guide plate, a light conversion layer, a light source, and a reflecting surface is provided. The light guide plate has a light emitting surface, a back surface, a first side, and a second side. The light emitting surface is opposite to the back surface, and the first side and the second side are connected between the light emitting surface and the back surface. The light conversion layer is disposed on the light emitting surface. The light source is disposed at the first side. The reflecting surface is located at the second side. An included angle between the reflecting surface and an extending direction of the light emitting surface is an acute angle. A light beam emitted by the light source enters the light guide plate through the first side, and is reflected by the reflecting surface after being transmitted through the light guide plate.
