Virtual image display apparatus
Abstract:
A light guide section is directly fixed to a frame via an attachment portion that is part of a peripheral portion of the light guide section, whereby not only can the light guide section be readily fixed and the weight of a virtual image display apparatus can be readily reduced but also the strength at which the frame supports the light guide section is improved. Further, except the attachment portion, the remaining peripheral portion of the light guide section is not fixed to the frame. Therefore, when the light guide section and the frame differ from each other in terms of the coefficient of thermal expansion, the light guide section is allowed to expand with respect to the frame, whereby no distortion, deformation, or breakage of the light guide section will occur.
