Zusammenfassung:	An edge lighting backlight module includes a module frame, a light guide plate, at least one light emitting device, and a reflection lampshade. The module frame has a central space and a light source disposing space. The light guide plate is disposed in the central space of the module frame. The light emitting device is disposed in the light source disposing space of the module frame, and the light emitting device and the light guide plate are located at different horizontal levels. The reflection lampshade is disposed in the light source disposing space of the module frame, and located at one side opposite to the light guide plate. The light emitting device emits a light source toward the reflection lampshade, and the reflection lampshade reflects the light source so that the light source enters the light guide plate along an optical axis parallel to the light guide plate.
