DISPLAY DEVICE
First Claim
1. A display device comprising:
- an image forming device;
an optical device configured to guide light, the optical device having a first surface region located on a first side of the optical device, wherein light output from the image forming device is incident upon the first surface region, is guided within an interior of the optical device, and is output from the optical device;
a dimmer configured and arranged to adjust an amount of external light incident upon the optical device, the external light originating from outside of the display device, wherein the dimmer is located on a second side of the optical device opposite the first side of the optical device; and
a light shielding member configured and arranged to shield external light from being incident on a portion of the second side of the optical device opposite the first surface region and to shield external light from being incident on a first portion of the dimmer without also shielding external light from a second portion of the dimmer, different from the first portion of the dimmer.

Abstract
There is provided a display device including (I) an eyeglass-shaped frame configured to be mounted on a head of an observer, and (II) an image display device attached to the frame. The image display device includes (A) an image forming device, and (B) an optical device on which light output from the image forming device is incident, in which the light is guided, and from which the light is output. A dimmer configured to adjust an amount of external light incident from outside is installed on a side opposite to a side on which the image forming device of the optical device is disposed. A light shielding member configured to shield incidence of external light on the optical device is disposed in a region of the optical device on which light output from the image forming device is incident.
