Abstract
According to one embodiment, a display device includes a display module configured to emit display light which is linearly polarized light, a first structure including a first retardation film facing the display module, a holographic optical element facing the first retardation film, and a second retardation film facing the holographic optical element, a second structure including a reflective polarizer facing the second retardation film, and a transparent substrate facing the reflective polarizer, and a variable mechanism by which an interval between the first structure and the second structure is made variable.
