First Claim
Patent Images
1. A head mounted display comprising:
- a glasses-type frame to be worn on a head of an observer;
two optical modules including;
two image creation devices, and two light guides having two light guide plates,coupled one-to-one with the two image creation devices and placed closer to a center of a face of the observer than the image creation devices are as a whole, to guide light beams output from the image creation devices and to output the light beams toward pupils of the observer; and
an optical plate supporting the two light guides, wherein the optical plate is;
attached to a center part of the frame;
attached to a periphery part of each of the two light guides via an adhesive bond;
located such that it covers the light beams propagating through the two light guide plates; and
located on the opposite side of the two light guide plates as the head of the observer when the glasses-type frame is worn by the observer;
wherein the center part of the frame is thicker than an outside part.
