Abstract
It is an object of the present invention to provide a display apparatus having a configuration and a structure that enable virtual images to be observed by an observer to exhibit high contrast, and enable the observer who uses the display apparatus to safely act in a real environment while reliably recognizing an external environment. A display apparatus of the present invention includes: a frame to be mounted to a head of an observer; an image display apparatus attached to the frame; and a dimming apparatus. The image display apparatus includes an image forming apparatus, and an optical apparatushaving a virtual-image forming regionin which virtual images are formed. The optical apparatusoverlaps with at least a part of the dimming apparatus. When the dimming apparatusoperates, a light blocking rate of the dimming apparatus decreases, for example, from an upper region and an outer-side region of a virtual-image-forming-region facing regiontoward a central portion of the virtual-image-forming-region facing region.
