Abstract
A liquid crystal display device is provided where deterioration of the liquid crystal panel is prevented while reducing power consumption. A liquid crystal panel (12) includes a display region (26) in which a video is displayed. The display region (26) includes a plurality of sub-regions (26A, 26B, 26C, 26D). A drive unit (14) rewrites the display on at least one of the plurality of sub-regions (26A, 26B, 26C, 26D) based on a video signal. An identification unit (38) identifies the one of the plurality of sub-regions (26A, 26B, 26C, 26D) on which the drive unit (14) has not rewritten the display for a predetermined number of frames. An output unit (40) outputs an interrupt signal for requesting a video signal for rewriting the display on the sub-region identified by the identification unit.
