Abstract

A backlight assembly includes a light supplying part and a light guide plate. The light supplying part includes a white light source and a monochromatic light source that generates a monochromatic light. The white light source generates a white light responsive to an electric power provided from exterior to the backlight assembly. The light guide plate is disposed adjacent to a side of the light supplying part. The light guide plate includes a light guiding region where the white light and the monochromatic light are guided into and a peripheral region that surrounds the light guiding region. Therefore, color reproducibility of an LCD apparatus is increased so that an image display quality of the LCD apparatus is improved.
