Abstract
A stereoscopic image display apparatus includes an illumination unit in which a plurality of light sources are disposed, a transmission unit that transmits light arriving from the illumination unit for each pixel based on an input image, and changes transmittance of the light for each pixel; a barrier unit that allows the light transmitted through the transmission unit to be viewed as a right-eye image and a left-eye image; and a control unit that divides an area of the illumination unit based on the input image and controls emission luminance of the light source for each area.
