1. A display device comprising:
a display panel including a polarizer and comprising a display area configured to emit display light which is linearly polarized light;
a holographic element configured to reflect light having a specific incident angle and configured to transmit light having an incident angle different from the specific incident angle;
a retardation film provided between the display panel and the holographic element;
a transflective element which faces the holographic element across an intervening space, is configured to reflect, of the light which passed through the holographic element, first circularly polarized light, and is configured to transmit second circularly polarized light rotating in an opposite direction of the first circularly polarized light; and
a lens element which faces the transflective element and has a lens effect of condensing the second circularly polarized light which passed through the transflective element.
