Abstract

A display device includes a display which is configured to display an image; a backlight which is turned on in the rear face of the display; a storage unit which is configured to store luminance characteristics at the center of the display; an optical sensor which is configured to measure luminance in the periphery of the display; and a signal processing unit which is configured to correct the measured value measured with the optical sensor in the periphery of the display based on luminance characteristics stored in the storage unit, thus controlling the luminance of the display based on the corrected measured value.
