Abstract
A display device includes: a display panel, a reflective polarization plate, a polarization control panel, a polarization plate, and an optical layer arranged in a stated order. The reflective polarization plate transmits a component polarized in the first direction and reflects a component polarized in the second direction, in light incident on the reflective polarization plate. The polarization control panel is switchable between a first state in which light incident on the polarization control panel has its polarization direction changed and is transmitted accordingly and a second state in which the incident light has its polarization direction maintained and is transmitted accordingly. The polarization plate transmits a component polarized in the first direction or a component polarized in the second direction, in light incident on the polarization plate. The optical layer disturbs a polarization direction of light incident on the optical layer and transmits the light accordingly.
