Abstract: A head-up display apparatus forms a virtual image of a display image viewed from a viewpoint region by projecting the display image onto a projection face. The apparatus includes a screen member and an optical device. The screen member includes an image formation face that forms the display image. The optical device includes a reflection face, which receives and reflects the display image by the image formation face, to project onto the projection face. The image formation face includes, in a grid array, convex portions and concave portions, which are convex and concave from a virtual reference face and alternated with each other along x axis and y axis. A perpendicular line to the virtual reference face at any position of the image formation face passes through an outside of the reflection face of the optical device.
