    摘要: A display module and a display device are provided. The display module includes a backlight module; a light control cell; a display liquid crystal cell; a first polarizer; a second polarizer; and a composite optical film. Along a thickness direction of the display module, the light control cell is disposed between the backlight module and the display liquid crystal cell and on a light-exiting surface of the backlight module; the first polarizer is disposed on a side of the display liquid crystal cell facing away from the light control cell; the second polarizer is disposed between the display liquid crystal cell and the light control cell; the composite optical film is disposed between the display liquid crystal cell and the backlight module; and the composite optical film is configured to transmit P-polarized light and reflect S-polarized light.

    摘要: Provide are an optical element that can improve a utilization efficiency of light while increasing an optical path length, an image display unit, and a head-mounted display. The optical element includes, in the following order: a first absorptive linearly polarizing plate; a first reflective linearly polarizing plate; a first retardation plate; a partially reflecting mirror; a second retardation plate; and a second reflective linearly polarizing plate, in which a turning direction of circularly polarized light that is reflected from the first reflective linearly polarizing plate in a case where light transmits through the first retardation plate and is incident into the first reflective linearly polarizing plate is opposite to a turning direction of circularly polarized light that is reflected from the second reflective linearly polarizing plate in a case where light transmits through the second retardation plate and is incident into the second reflective linearly polarizing plate.

    摘要: A first configuration of a display device includes: a first display unit that emits first image light and second image light; a first polarizing half mirror that transmits one of the first or second image light and reflects the other; a first reflective mirror on an optical path of the first polarizing half mirror; and a first λ/4 plate between the first reflective mirror and the first polarizing half mirror. A second configuration includes: a second display unit that emits third image light and fourth image light; a half mirror; and a third reflective mirror that reflects, toward the half mirror, the third image light reflected by the half mirror. A third configuration includes: a second display element; and a first reflector that reflects fifth image light from the second display element. The first reflector includes reflective surfaces for forming display images based on the fifth image light.

    摘要: A polarizer and a display device are provided. In the polarizer, on a basis of using an optical compensation layer to compensate a birefringence of liquid crystal molecules in a liquid crystal layer, a liquid crystal compensation layer is configured to compensate the birefringence of the liquid crystal molecules in the liquid crystal layer. The liquid crystal compensation layer adjusts a compensation value through a refractive index difference and a thickness of the liquid crystal molecules, so an adjustment range is large and a restriction is small, which can be matched with a high phase difference of the display device, and further improves side-view light leakage in a dark state of the liquid crystal display.

    摘要: To provide an image display apparatus and a display apparatus including the image display apparatus which are capable of achieving further simplification of an apparatus configuration, achieving further speed-up of generation of a super multi-view, achieving further suppression of an apparatus manufacturing cost, and achieving further suppression of an adjustment cost of an optical axis. Provided is an image display apparatus including a light source, at least two image forming apparatuses, a quarter-wave plate, a beam splitter, a lens, and an eyepiece for each of eyes of a user. Out of the at least two image forming apparatuses, a first image forming apparatus is provided in a predetermined angular direction with respect to an optical axis of the lens, and a second image forming apparatus is provided in a direction substantially perpendicular to the optical axis of the lens. Light emitted from the light source is incident on the first image forming apparatus and the second image forming apparatus via the lens, the beam splitter, and the quarter-wave plate in this order. First image light emitted from the first image forming apparatus and second image light emitted from the second image forming apparatus are incident on each of the eyes of the user via the quarter-wave plate, the beam splitter, and the eyepiece in this order.
