Abstract
A head-up display device includes: an image generator that emits light; and a display member including: a projection surface onto which the light is projected, wherein when the light is emitted to the projection surface, the light is reflected from the projection surface to display a real image passing through the display member and a virtual image; and a plate material including: a pair of optical surfaces, one positioned nearer to an observer side than the other, and either of which can serve as the projection surface; an end surface connecting peripheries of the pair of optical surfaces; and an end main surface formed at a predetermined a distance from the end surface to a reference line passing through a reference point and being orthogonal to a tangent plane at the reference point.
