Abstract:
According to one embodiment, a display device includes a display panel configured to emit display light of linearly polarized light, a first semi-transparent element transmitting first circularly polarized light and reflecting second circularly polarized light, a first retardation film, a second semi-transparent element reflecting the first circularly polarized light and transmitting the second circularly polarized light, a second retardation film having a refractive anisotropy in which refractive indexes of directions orthogonal to each other in a plane are substantially equivalent to each other and a refractive index in a normal is different from a refractive index in a plane, and a first element having a lens action of condensing the second circularly polarized light.
