DISPLAY DEVICE

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.
