Display device

A display device comprising:

• a display panel having a display region 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 in a reverse direction to the first circularly polarized light;
• a first retardation film arranged between the display panel and the first semi-transparent element;
• a second semi-transparent element separated from the first semi-transparent element, reflecting the first circularly polarized light, and transmitting the second circularly polarized light;
• a second retardation film arranged between the first semi-transparent element and the second semi-transparent element, and 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 opposed to the second semi-transparent element and having a lens action of condensing the second circularly polarized light.
