Abstract: An electronic device capable of detecting a user's body movements is to be provided. The electronic device is display equipment worn in front of the user's eye and capable of detecting the blinking action. The electronic device includes a display apparatus and a light source in a housing, and the display apparatus includes a light-emitting device and a light-receiving device in a display portion. Light emitted by the light source is incident on the user's eye and the vicinity thereof through a mirror and reflected, and the reflected light is detected by the light-receiving device. The amount of light reflected by the eyelid and that by the eyeball are different from each other, which enables the blinking action to be detected. The detection of the blinking action enables the user's fatigue state to be estimated.
