Abstract
An optical unit housing section and a light guide device are supported by a frame. Durability of sections having an optical function in an entire apparatus is maintained. The frame is arranged on a side closer to the nose of an observer than the optical unit housing section and reduced in size. Consequently, a virtual image display apparatus can give an impression that the virtual image display apparatus is small in size in appearance as a whole. Further, it is possible to attain a reduction in the weight of the entire virtual image forming apparatus. Compared with a structure in which the entire apparatus is covered with a case-like member, the virtual image display apparatus can be formed in a shape closer to a form of eyeglasses. It is possible to attain design with apparent voluminousness suppressed.
