    Abstract: In a display apparatus body (10A), a first polarization plate (31), a first wave plate (32), a reflection layer (33), a second wave plate (35), and a second polarization plate (36) are arranged between a display element (De) and a lens (S) and are lined up in this order from the display element (De) toward the lens (S). Further, the reflection layer (33) includes reflection regions (E1) that correspond to positions of non-light emission regions (R2) of the display element (De) and that reflect light and includes light transmission regions (E2) that correspond to positions of a plurality of light emission regions (R1) and that transmit light. This can obtain a display apparatus that can improve the use efficiency of light emitted from a display element.

    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.

    Abstract: Provided is a head-mounted display in which it is easy to photograph eyes of a user that wears the head-mounted display. The HMD that is worn by the user includes a display unit disposed in front of the eyes of the user, an optical system disposed between the display unit and eyes of the user, and an imaging unit disposed between the display unit and the optical system, the imaging unit imaging the display unit in which an image of the eyes of the user is reflected.
