Abstract
A display device includes an imaging element layer, a light-emitting element layer located closer to a display surface side than the imaging element layer, a selective reflection layer located between the imaging element layer and the light-emitting element layer and transmitting one of right-handed circularly-polarized light and left-handed circularly-polarized light and reflecting the other, and a retardation layer located between the selective reflection layer and the light-emitting element layer and having a switchable phase difference.
Claims21
