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. 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.
