Kind Code:

Abstract:
A head-up display device projects a virtual image. The head-up display device includes a display, a first optical member, a second optical member, and an adjuster. The display outputs light that becomes a display image corresponding to the virtual image. The first optical member reflects the light incident from the display. The second optical member reflects or transmits the light reflected by the first optical member such that the virtual image is projected. The adjuster moves the first optical member to adjust a projection distance of the virtual image. The adjuster changes a distance between the first optical member and the second optical member and an inclination angle of the first optical member with respect to the display according to the projection distance of the virtual image.
