Abstract

A head mounted display comprises a transmission-type display device for displaying prescribed images while transmitting outside light, a head mounted device for supporting the display device in front of the face, and a visor for reducing the quantity of outside light incident on the display device. The visor is installed in such a way that it can move between a position in which the outside front surface of the display device is covered and a position in which this surface is open. A living space or other external environment can be perceived without any impediment to viewing even when the images projected on the image display mechanism are being viewed.
