Abstract
A display device includes: a first panel including a first image-forming surface for forming a first image visually recognized by a user and a plurality of first pixels; a second panel including a second image-forming surface for forming a second image visually recognized by the user and a plurality of second pixels; and a half-wavelength plate located between the first image-forming surface and the second image-forming surface. The half-wavelength plate includes an optical axis, is configured to be capable of transmitting incident light from either one panel of the first panel and the second panel, and of emitting light as emission light to the other panel. A polarization direction of the emission light from the half-wavelength plate is determined based on a polarization direction of the incident light on the half-wavelength plate and a direction of the optical axis.
