Abstract
A display apparatus is provided which can achieve suitable screen display luminance depending on video content as well as can reduce power consumption sufficiently. A liquid crystal display apparatus includes a liquid crystal panel that displays video and a light source that illuminates the liquid crystal panel, and the emission luminance of the light source is controlled depending on the genre of the video displayed on the liquid crystal panel. The emission luminance of the light source is adjusted while maintaining approximately constant white chromaticity (white balance).
