Abstract: A display device includes: a substrate temperature obtainer that obtains a substrate temperature of a substrate of a display panel; a power obtainer that obtains an amount of power used by a plurality of segmented regions of the display panel, based on image data displayed on the display panel; a first increased temperature deriver that derives an increased temperature of a panel surface of the display panel based on the amount of power used by the plurality of segmented regions; and a surface temperature estimator that estimates a temperature of the panel surface based on the substrate temperature and the increased temperature.
