Abstract
A display device includes a projection lens that transmits an image light, a prism mirror that receives the image light emitted from the projection lens through a light incident surface, reflects the image light with an inner reflection surface, and emits the image light from a light emission surface, and a see-through mirror that reflects a part of the image light emitted from the prism mirror toward a pupil position, wherein an intermediate image is formed between the inner reflection surface and the see-through mirror, and the light emission surface has a first region and a second region that is higher a refractive power than the first region.
