A display element (7) is turned off by stopping power supply when an image is displayed on a display section (6). When an image is displayed on the display section (6), the user is mostly observing the image with a head mount display (1) mounted on the user. At such time, since the display element (7) cannot be visually recognized, problem does not occur even when the display element is turned off. Furthermore, since the display element (7) is not required to be supplied with power supply, the service life of a battery is lengthened by such quantity.
