Abstract: A display device includes: a display that emits image light; an optical element that is disposed away from the display, the optical element being switchable between a first state in which the optical element reflects the image light and a second state in which the optical element transmits the image light; a first reflector that is disposed on an opposite side of the optical element relative to a side on which the display is disposed; and a controller that controls the display and the optical element. When the controller causes the display to repeatedly output a first image and a second image in an alternating manner, the controller switches the optical element between the first state and the second state in synchronization with the first image and the second image.

Abstract: 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.

Abstract: A display device includes: a display element; an optical element including opposing first and second surfaces; and a casing. When the optical element placed such that its height direction matches the vertical direction is viewed in a cross section including the vertical direction, and t1/t2 defines a thickness ratio, where t1 and t2 represent a thickness of upper and lower ends of the optical element, respectively, in a reference direction parallel to a normal line from an origin of the second surface, a value of the thickness ratio at which the width of the display element is equal to a width of the optical element is defined as an upper limit, and a value of the thickness ratio that is equal to a depth of the casing when the thickness ratio is equal to the upper limit, and less than the upper limit is defined as a lower limit.

Abstract: An imaging device according to an embodiment includes a lens barrel, a board, a housing, and an adhesive member. A lens is arranged in the lens barrel. An imaging element is mounted on the board, the imaging element converting light received through the lens into an image signal. The housing houses the board, and includes a hole at a position that faces the imaging element, one end side of the lens barrel being fitted into the hole. The adhesive member is provided between an outer peripheral surface of the lens barrel and an inner peripheral surface of the hole, in a state where the one end side of the lens barrel is fitted into the hole, and the adhesive member fixes the lens barrel to the housing.
