Abstract: Provided is a display device that can be readily reduced in size and thickness, and is capable of reducing luminance unevenness within an image. The display device includes: a projection optical system that projects image light at infinity; and a first propagation optical system, a second propagation optical system, and a third propagation optical system, which sequentially enlarge, in one direction, the image light projected from the projection optical system, in which the image light output from the third propagation optical system allows an image to be observed.

Abstract: Provided is an image display device, including: a light flux emitter (10) which emits a plurality of parallel light fluxes; and a controller (20) which periodically subjects, to two-dimensional deflection, the parallel light fluxes emitted from the light flux emitter (10), based on a scan signal, and controls, synchronously with the scan signal, light intensity of the plurality of parallel light fluxes based on a light intensity control signal based on image information input thereto, in which: the light flux emitter (10) has at least a plurality of photonic crystal semiconductor lasers (11a) which emit the plurality of parallel light fluxes and are two-dimensionally arranged; and the parallel light fluxes emitted from the plurality of photonic crystal semiconductor lasers (11a) are controlled in light intensity, based on the light intensity control signal.

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.
