    • A backlight unit which includes a structure in which the sensitivity of a light sensor for detecting color reproducibility of white light is increased, and a liquid crystal display (“LCD”) device having the same. The backlight unit includes a light source which generates light, a light guide plate which guides the light incident from the light source, a light sensor which detects the light emitted from the light guide plate and a mold frame which receives the light source, the light guide plate, and the light sensor. The mold frame includes a receiving recess which receives the light sensor, and a light sensing structure formed on a sidewall thereof being in contact with a side of the light guide plate which reflects the light emitted from the light guide plate and provides the light emitted from the light guide plate to the light sensor.
    • 包括其中用于检测白光的颜色再现性的光传感器的灵敏度增加的结构的背光单元和具有其的液晶显示器(“LCD”)装置。 背光单元包括产生光的光源,引导从光源入射的光的导光板,检测从导光板发出的光的光传感器和接收光源的模架, 导板和光传感器。 该模架包括容纳该光传感器的容纳凹部和形成在其侧壁上的光检测结构,其与导光板的一侧接触,该侧反射从导光板发出的光,并提供从 导光板到光传感器。
