Abstract

An edge-lighting type backlight module includes a light guide plate, a light source module, a back plate, a thermal conductive element, and a thermal insulating element. The light guide plate has a light-emitting surface, a bottom surface opposite the light-emitting surface, and at least one side surface connected between the light-emitting surface and the bottom surface. The light source module is disposed adjacent to the side surface, and the back plate is disposed adjacent to the bottom surface. The thermal conductive element has a base portion touching the light source module and an extension portion extending to one side of the back plate. The thermal insulating element is connected between the back plate and the thermal conductive element to reduce the heat conduction between the light source module and the back plate.
