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.
