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, an optical device, and an operation receiver. The display device is 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. The optical device is 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. The operation receiver switches 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.
