Abstract
A display apparatus includes a first mirror and a half mirror between a display device and a concave mirror. The first mirror reflects emission light emitted from an elongate display surface of the display device, toward the half mirror. The half mirror reflects the light reflected by the first mirror, toward the concave mirror. The concave mirror reflects the light reflected by the half mirror, toward the half mirror. In a top view of the display apparatus, a line passing through a center of the display surface in a longitudinal direction and parallel to the longitudinal direction and a tangent line passing through a center of a reflection surface of the concave mirror in a longitudinal direction and parallel to the longitudinal direction intersect at a predetermined angle.
