Abstract: Each of a plurality of optical elements that are arrayed in a lattice pattern in a screen member which diffuses a laser beam incident from a projector to guide the laser beam toward a projection surface has a curved surface on a side thereof, and the curved surface has a common convexly curved shape, and diffuses the laser beam which is emitted from the curved surface toward the projection surface. The respective optical elements include a plurality of reference elements which serve as a reference and a plurality of peripheral elements which are adjacent to the respective reference elements. The respective reference elements and the respective adjacent peripheral elements are formed by offsetting surface vertexes of the curved surfaces in a stepwise manner. Offset amounts generated between the respective reference elements and the respective adjacent peripheral elements are different from each other.

Abstract: An HUD device includes a laser scanner that projects laser light carrying a display image, and a screen member that has a plurality of optical elements arrayed in the form of a grating, and diffuses laser light which emanates from the laser scanner and enters the optical elements toward a projection surface. The optical elements have curved surfaces, which take on a convexly curved form as a common curved form, formed as their faces, and diffuse laser light which is emitted to the projection surface from the curved surfaces. A sag quantity from each of surface vertices of the curved surfaces to each of boundaries among the optical elements differs between adjoining optical elements.

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.

The optical elements have curved surfaces, which take on a convexly curved form as a common curved form, formed as their faces, and diffuse laser light which is emitted to the projection surface from the curved surfaces. The optical elements are configured so that an element width differs in at least one array direction of the array of the grating between adjoining optical elements.
