摘要： The present invention provides a display device capable of realizing an appropriate screen display luminance in accordance with a video feature quantity and brightness around and sufficiently reducing power consumption. A liquid crystal display apparatus (1) includes: a liquid crystal panel (20) for displaying a video by an input video signal; a backlight unit (17) as a light source for irradiating the liquid crystal panel (20); and a brightness sensor (24) for detecting the brightness around the liquid crystal display apparatus (1). According to the brightness detected by the brightness sensor (24), luminance conversion characteristic defining the light emission luminance of the backlight for the feature quantity (such as APL) of the input video signal is changed. Here, the luminance conversion characteristic is changed so that the light emission luminance is reduced as the brightness around the liquid crystal display apparatus becomes darker and the position of the characteristic modification point as the point where the slope of the luminance conversion characteristic is changed is shifted in the direction of the feature quantity change. According to the obtained luminance conversion characteristic, the light emission luminance of the backlight is controlled.
