PROBLEM TO BE SOLVED: To provide a head-up display device that is less likely to allow condensation of light emitted from a light source to cause alteration of a lens array.SOLUTION: A head-up display device of the present invention includes a display member 113, a light sources 111a that emit light beams L0, a lens array 111c that splits the light beams L0 and generates a plurality of images of the light sources 111a, and a field lens 111d that makes the light beams L0 from the images of the light sources 111a generated by the lens array 111c enter the display member 113 at a prescribed angle. The lens array 111c is shaped such that a focal point P1 in a first direction does not intersect with a focal point P2 in a second direction perpendicular to the first direction on the lens array 111c.SELECTED DRAWING: Figure 2 |
