    Abstract: A display device includes a temperature sensor which is arranged in the inside of a housing, and a control unit which calculates a temperature of a display panel based on an output value of the temperature sensor. The control unit calculates the temperature of the display panel based on a current output value of the temperature sensor and an output value of the temperature sensor received prior to the receiving of the current output value. With such a display device, the temperature of the display panel can be calculated with high accuracy even when a temperature of a device which constitutes a heat source is changed.
