Original Abstract Submitted
A display apparatus includes a display panel that includes a liquid-crystal panel and a backlight arranged behind the liquid-crystal panel, and a controller that controls a luminance of the backlight and a transmittance ratio of the liquid-crystal panel. The controller is configured to: when a refresh rate at which an image is displayed on the display panel is switched, vary the luminance of the backlight such that a variation of a luminance of the display panel between before and after switching of the refresh rate falls within a predetermined range; vary the transmittance ratio of the liquid-crystal panel such that the variation of the luminance of the display panel falls within the predetermined range within a time duration that lasts until the luminance of the backlight reaches a target value; and restore the original transmittance ratio of the liquid-crystal panel after elapse of the time duration.
