Abstract: A light source module including a back frame, a light guide plate (LGP), and at least one light emitting device is provided. The back frame has a baseboard. The LGP is disposed on the back frame, and has a first surface, a second surface opposite to the first surface, and a light incident surface, wherein the second surface faces toward the baseboard. The light emitting device is disposed beside the light incident surface. The light source module further includes a thermal insulating element, which is disposed between the baseboard and the second surface, and is located adjacent to the light incident surface.

Abstract: A light guide module includes a light guide plate and a diffuse reflector. The light guide plate has a light incidence surface, a light exiting surface, and a bottom surface, wherein the light exiting surface is opposite to the bottom surface, and the light incidence surface is connected with the light exiting surface and the bottom surface. The diffuse reflector is secured to the bottom surface of the light guide plate by an adhesive pattern layer, wherein the adhesive pattern layer is formed by a plurality of light-transmissive adhesive gels, and these light-transmissive adhesive gels do not contain any diffusive particles. A backlight module using the light guide module mentioned above and a fabricating method for the light guide module are also provided.
