Abstract

A display apparatus includes an optical image projection system, first optical propagation system, and second optical propagation system. The optical image projection system projects image light to infinity. The first optical propagation system propagates the image light projected from the optical image projection system in the x-direction. The first optical propagation system deflects a portion of the image light. The second optical propagation system includes a second input deflector that deflects the image light deflected by the first output deflector. The second optical propagation system propagates the image light deflected by the second input deflector in the y-direction and deflects a portion of the image light. The light beam width in the y-direction of the image light emitted from the optical image projection system and the length in the y-direction of the first light guide are greater than the length in the y-direction of the second input deflector.
