Abstract
Provided is a display device in which generation of a ghost can be restrained. A polarizing plate is disposed adjacently to a display section. A ¼ wavelength plate is disposed adjacently to the polarizing plate. A polarizing plate is disposed adjacently to a lens. A ¼ wavelength plate is disposed adjacently to the polarizing plate. A beam splitter is disposed between the ¼ wavelength plate and the ¼ wavelength plate. The beam splitter is disposed at such a position that the air-equivalent optical path length of light that is reflected by the polarizing plate and is thereafter reflected by the beam splitter from emission of the light from the display section to transmission of the light through the lens and the air-equivalent optical path length of light that is reflected by the beam splitter and is thereafter reflected by the polarizing plate from emission of the light from the display section to transmission of the light through the lens are equal.
