Abstract: A display device includes: a display; an optical element including a first surface and a second surface; and a reflective member provided on the second surface. The first surface is a convex cylindrical surface whose axial direction is a first direction (parallel to the X axis), allows light emitted from the display to enter, and allows the light reflected by the reflective member to exit. The second surface is a convex cylindrical surface whose axial direction is a second direction (parallel to the Y axis) orthogonal to the first direction. The reflective member includes a reflective surface that reflects the light that has entered from the first surface toward the first surface. The reflective surface is a concave cylindrical surface whose axial direction is the second direction.

Abstract: A display apparatus includes a housing and at least one mirror. The housing can be detachably mounted on a display and includes an entrance that allows light emitted from the display to enter the interior of the housing with the housing mounted on the display and an exit that allows the light having entered the interior of the housing through the entrance to exit to the exterior of the housing. The at least one mirror reflects the light having entered the interior of the housing through the entrance to the exit.

Abstract: An optical device includes: a display; an optical element that includes a first face and a second face facing the first face, the optical element receiving light from the display through the first face, reflecting the received light on the second face, and emitting the reflected light through the first face; a housing that accommodates the display and the optical element; and a fixing structure that fixes the optical element by holding the optical element from different sides of the optical element.

Abstract: A display system includes: a display that emits light corresponding to image information; a half mirror that receives the light emitted, reflects, as reflected light, a first component of the light received, and transmits a second component different from the first component; and a first reflecting mirror having a concave surface that receives and reflects the reflected light toward the half mirror. The half mirror includes a first retardation film, a first support substrate, and a reflective polarizing film stacked in this order from a side on which the light emitted is received. The first retardation film changes a phase of the light received. The first support substrate is light-transmissive. The reflective polarizing film reflects a first polarized component and transmits a second polarized component different from the first polarized component.

Abstract: A display system includes: a display device switchable between an emitting state where first image light is allowed to be emitted from the display device and a non-emitting state where the first image light is not allowed to be emitted from the display device; an optical device switchable between a reflecting state where light coming from a back of the mobile body is reflected from the optical device and a transmitting state where the light passes through the optical device; and an operation receiver that receives an operation for switching the display system between a first mode where the display device is in the emitting state while the optical member is in the transmitting state and a second mode where the display device is in the non-emitting state while the optical member is in the reflecting state.
