PROBLEM TO BE SOLVED: To provide a head-up display device that enables reduction in unevenness of a virtual image generated by interference of laser light while maintaining a simple construction regarding a screen member such as a micro lens array and the like.SOLUTION: A head-up display device 100 allows a projection of a display image 71 to be drawn on a scanning surface 31 by scanning of the laser light to view a virtual image 70 of the display image 71 from a preliminarily prescribed eye box 60. In a screen 30, the scanning surface 31 on which the display image 71 is drawn is formed by arraying convex curve parts 32 of micro lenses 34. A MEMS mirror part 26 generates first laser light L1 and second laser light L2 to be irradiated from a mutually different direction. By overlapping each of these pieces of laser light L1 and L2 with each other, light-dark generated by the interference in the one laser light acts so as to complement light-dark generated by the interference in the other laser light. |
