Abstract: A display device includes first light emitting devices arranged in a line in a protective member, second light emitting devices parallel to and alternately arranged with the first light emitting devices, and optical member supporters in the protective member between the first and second light emitting devices. Each optical member supporter is positioned at a center of a parallelogram defined by two adjacent first light emitting devices and two adjacent second light emitting devices, and each transparent optical member supporter includes a first surface that faces one of the first light emitting devices and a second surface opposite the first surface that faces one of the second light emitting devices. Each optical member supporter includes a plate portion having the first and second surfaces, and a hook portion that extends through the protective member. A width of the plate portion decreases with increasing distance from the hook portion.

Abstract: A backlight assembly includes a light emitting unit, a reflective sheet, and a bottom cover. The light-emitting unit includes a light source emitting light and an optical system. The optical system is spaced apart from the light source in a direction in which the light emitted from the light emitting unit initially travels. The optical system has a curved shape that reflects a portion of the light emitted from the light source and transmits a remaining portion of the light emitted from the light source. The reflective sheet is disposed under the light-emitting unit to re-reflect the light reflected by the optical system. The bottom cover accommodates the light emitting unit and the reflective sheet. Thus, the light-spreading angle of the light-emitting unit becomes wide.
