Abstract

A head-up display apparatus includes a projector that projects a laser beam and a screen including a plurality of optical elements that are arranged in a grid pattern. The screen diffuses the laser beam, which has entered into the plurality of optical elements from the projector, toward the projection plane. Each of the plurality of optical elements has a curved surface formed into a convex or a concave shape on an outside surface of the screen. One of the plurality of optical elements has a thickness at a curvature center point that is different from that of the other of the plurality of optical elements immediately adjacent to the one of the plurality of optical elements.
