Display device
First Claim
1. A display device comprising:
- (I) a frame configured to be mounted on a head of an observer;
(II) an image display device attached to the frame, wherein the image display device includes;
(A) an image forming device, and(B) an optical device having a first side including a first surface region on which light output from the image forming device is incident, an interior region in which the light is guided, and a second surface region from which the light is output;
(III) a dimmer configured and arranged to adjust an amount of light transmittance to the optical device of external light incident from outside of the display device, wherein the dimmer is located on a second side of the optical device opposite the first side and is configured to be operated at at least three different light transmittance states; and
(IV) a light shielding member configured and arranged to shield incidence of the external light on a portion of the second side of the optical device opposite the first surface region and a first portion of the dimmer so as to inhibit the external light from reaching the portion of the second side of the optical device and the first portion of the dimmer without also inhibiting the external light from reaching a second portion of the dimmer that is 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.
