A display device according to the invention includes a light guiding body that guides image light, an incidence portion that makes the image light incident on the light guiding body, and an emission portion that makes the image light emitted from the light guiding body. The emission portion includes a plurality of partially reflecting mirrors, and is configured with a first partially reflecting mirror group having a relatively high reflectance of S-polarized light components and a second partially reflecting mirror group having a relatively high reflectance of the P-polarized light components. The first partially reflecting mirror and the second partially reflecting mirror are alternately arranged in an arrangement direction, and emit light of a polarized state including S-polarized light components and P-polarized light components.
