The invention provides a display device which is capable of adjusting the image refresh rate to an optimal value regardless of the type of image data, and thus has low power consumption. The display device includes a liquid crystal panel for displaying images, a liquid crystal controller for refreshing images displayed in the liquid crystal panel according to an image data signal, and a CPU for inputting the image data signal to the liquid crystal controller. In the display device, the CPU has a discrimination section for discriminating whether the image data is a moving image or a still image based on an input interval of the image data from the CPU to the liquid crystal controller, and the liquid crystal controller has an image refresh demand signal generation circuit for changing the image refresh rate of the liquid crystal panel based on the result of discrimination by the CPU.
