Abstract

A display device includes a light guide body including first holographic optical element and a second holographic optical element, and an image light emitter that emits image light to the light guide body. In addition, the first holographic optical element includes a plurality of first cells for emitting first image light toward the second holographic optical element, the first image light being obtained by diffracting the image light propagating inside the light guide body. In addition, the second holographic optical element includes a plurality of second cells for emitting second image light obtained by diffracting the first image light propagating inside the light guide body. In addition, an arrangement of the plurality of first cells is different from an arrangement of the plurality of second cells.
