Provided is a display device ( 100 ) which predicts a predicted temperature difference between a peripheral display area and an outer peripheral area of a display section ( 200 ) based on an input image signal from an image-signal input section ( 10 ). When the predicted temperature difference is a set reference value or more, the display device ( 100 ) controls luminance of an image displayed on the peripheral display area so as to be lowered. Therefore, the predicted temperature difference is predicted by using only the input image signal, and the luminance of the image displayed on the peripheral display area can be appropriately controlled without performing a calculation using the predicted temperature difference. Hence, such a luminance control for preventing breakage of the display section ( 200 ) can be easily performed.
