Claim:
1. A display device, comprising: an imaging unit configured to image a first image of a background viewable by a viewer and generate imaging data relating to the first image; an information acquisition unit configured to acquire first information relating to a second image inside the first image, the second image being on a line of sight of the viewer; a display unit including a first transmittance control plate, the semi-transmissive reflection plate being disposed between the first transmittance control plate and one eye of the viewer, the first transmittance control plate having a first region and a second region, the first region overlapping a part of the background and the semi-transmissive reflection plate as viewed by the one eye, the second region not overlapping the part of the background as viewed by the one eye, the second image being an image of the part of the background, the first transmittance control plate being configured to implement a first operation of causing a transmittance of the first region to be lower than a transmittance of the second region while causing the background light to be incident on the semi-transmissive reflection plate by causing the background light to pass through the second region; and a second transmittance control plate arranged with the first transmittance control plate, the second transmittance control plate having variable transmittance to light traveling toward other eye of the viewer, the second transmittance control plate being configured to implement an operation of causing the transmittance of the second transmittance control plate when the first transmittance control plate is implementing the first operation to be lower than the transmittance of the second transmittance control plate when the first transmittance control plate is not implementing the first operation.
