ABSTRACT:
An optical unit includes a base, a light-condensing member disposed on the base to condense a first portion of light that is incident onto the base and protrusion members disposed on a surface of the light-condensing member to scatter a second portion of the light that is incident onto the base. A backlight assembly includes light sources, an optical unit receiving light from the light sources to condense and scatter the light, and may also include an optical member disposed over the optical unit to enhance the front luminance of the light. A display device includes light sources, an optical module and a display panel. Thus, display quality of the display device may be enhanced.
