摘要：
The present invention concerns a display apparatus, which comprises a display device for displaying image information for the both eyes of an observer, a use-state detecting device for detecting a use state and a non-use state about whether or not the observer is observing the display device, a power supply device for supplying power to each element in the display apparatus, and a device for controlling the power supply device, based on a signal from the use-state detecting device.
