Abstract: A lower sheet disposed below a display panel includes a heat radiation layer having a first side and a second side facing the first side. A first film layer is disposed on the first side of the heat radiation layer. A second film layer is disposed on the second side of the heat radiation layer. A first resin layer is disposed between the heat radiation layer and the first film layer. A second resin layer is disposed between the heat radiation layer and the second film layer. A sealing layer is disposed on lateral sides of the heat radiation layer. The sealing layer directly contacts an entirety of the lateral sides of the heat radiation layer, and directly contacts at least a portion of lateral sides of the first resin layer and the second resin layer.

Abstract: A display device includes a display panel including a display area in which an image is displayed, and a light unit that includes: a light guide plate including a light receiving surface and a light emitting surface; a light source spaced apart from the light receiving surface while facing the light receiving surface and overlapping the display area; and a light diffusion member extending between the light receiving surface and the light source. The light diffusion member includes at least one of a first pattern formed on a surface of the light diffusion member facing the light emitting surface, and a second pattern formed on another surface of the light diffusion member, thereby implementing uniform brightness across the whole surface of the display panel.
