Abstract

A light source module includes a substrate, a reflective sheet, a plurality of light-emitting elements, an adhesive layer, and a frame. The reflective sheet is disposed on the substrate and has a side wall, a protrusion and a plurality of openings. The protrusion is protruded in a direction away from the substrate and has a mesh structure to define a plurality of dimming areas. The plurality of openings respectively correspond to the plurality of dimming areas. The plurality of light-emitting elements are disposed on the substrate, and the plurality of light-emitting elements are respectively disposed to pass through the plurality of openings. The adhesive layer is disposed between the substrate and the reflective sheet. The frame surrounds the reflective sheet and the plurality of light-emitting elements. The side wall of the reflective sheet is disposed on the frame. A display device of the invention is further provided.
