Abstract: The light source device includes a rear vessel, a light source substrate, a plurality of light-emitting diodes, a front cover, and a light diffuser. The rear vessel has a bottom plate and a first lower side plate connected to the bottom plate. The light source substrate is accommodated in the rear vessel. The plurality of light-emitting diodes is located over the light source substrate. The front cover has an upper plate and a first upper side plate connected to the upper plate, is located over the rear vessel, and accommodates the rear vessel. The light diffuser is accommodated in the front cover, is located over the plurality of light-emitting diodes, and is spaced away from the plurality of light-emitting diodes. The first lower side plate and the first upper side plate each have a notch.

Abstract: To provide a light source device capable of irradiating a liquid crystal display module with light at uniform luminance and a display device including the light source device. A light source device has a rear vessel a front cover, a light source substrate, a plurality of light-emitting diodes, and a light-diffusing plate. The front cover is located over and overlaps the rear vessel. The light source substrate, the plurality of light-emitting diodes, and the light-diffusing plate are accommodated between the rear vessel and the front cover. The plurality of light-emitting diodes is located over the light source substrate. The light-diffusing plate is located over, overlaps, and is spaced away from the plurality of light-emitting diodes. The rear vessel and the front cover each have a bottom plate and a side plate integrated with the bottom plate. In at least one of the rear vessel and the front cover, a portion of the side plate is bent to form a protruding portion overlapping the bottom plate. The light-diffusing plate is located over and overlaps the protruding portion.
