Abstract
A display device includes: a liquid crystal panel including a display surface on which frame images are displayed; a conversion portion for converting a frame image signal into a first image signal representing an image having a lower resolution and a second image signal representing an image having a higher resolution; and a liquid crystal driver for driving the liquid crystal panel with performing first and second scanning operations of the first and second image signals over pixels of the entire display surface. The liquid crystal driver performs the second scanning operation with targeting a drive luminance value which is set in response to an expected value of an achieved luminance value during the first scanning operation for the pixel of the display surface before the second scanning operation commences, and target luminance value for the pixels defined by the frame image signal.
