Abstract: A display apparatus includes a backlight assembly which provides a light and a display panel which receives the light provided from the backlight assembly to display an image. The backlight assembly includes a light source which generates the light, and a light guide plate. The light guide plate receives the light generated from the light source through an incident surface thereof as an incident light, and outputs the incident light through an exit surface thereof as an exit light. The light guide plate includes a first optical pattern and a second optical pattern. The first optical pattern is disposed corresponding to a first area of the exit surface and collects the incident light. The second optical pattern is disposed corresponding to a remaining second area of the exit surface excluding the first area, and collects the exit light.

Abstract: A display device includes a backlight unit generating light and a display panel displaying an image using the light from the backlight unit. The backlight unit includes a circuit board, a plurality of light emitting devices, a light guide member including a light incident surface, and a guide member disposed between a surface of the circuit board and the light incident surface. The guide member uniformly maintains a distance between the light incident surface and the light emitting devices. Thus, a light loss is reduced.

Abstract: A display apparatus includes a display panel which receives light to display an image. A light guide plate guides the light toward the display panel. A light source unit is disposed at a first side of the light guide plate to provide the light to the light guide plate. The light source unit includes a printed circuit board which includes a first area and a second area. A first light source is disposed on the first area and generates the light. A first stepped part is disposed on the second area and faces the first light source. A first adhesive part is disposed on the second area. The first stepped part reflects the light which is generated from the first light source toward the light guide plate, and the first adhesive part attaches the printed circuit board to the light guide plate.

Abstract: A backlight assembly includes a light source generating light and a first optical member diffusing the light. The first optical member includes a first diffusion member provided on an exit surface of the first optical member, from which the light exits, to diffuse the light. The first diffusion member includes a plurality of edges each having a curved shape and extending between the exit surface and a vertex of the first diffusion member. Accordingly, the light exiting through the exit surface is effectively diffused by the edges of the first diffusion member.
