摘要

Provided is a display device capable of suppressing reduction in display quality even during pause drive, and of altering the brightness of a light source in accordance with the image to be displayed. Pause drive at 7.5 Hz is performed in a liquid crystal display device having a CABC function. A transition period is provided during which an image is gradually changed when switching the image to be displayed from a bright image (X) to a dark image (Y). The length of an auxiliary transition period is 5 frames during the transition period. When the transition period starts, the length of the vertical display period switches from 8 frames to 1 frame. In other words, the 7.5 Hz pause drive switches to a 60 Hz normal drive. In this way, the screen is always refreshed during each auxiliary transition period during the transition period, as a result of the length of the vertical display period being made no greater than the length of the auxiliary transition period.
