摘要： A head-up display device that can generate a high-quality visual image as a virtual image is provided. A virtual image of a visual image to be visually recognized by a passenger 7 of a vehicle is generated by projecting respective visual images from a projector 4 to a first screen 20 and a second screen 21 via a first projection lens 16 and a second projection lens 17, and reflecting the visual images projected to the first screen 20 and the second screen 21 to a windshield 6 of the vehicle 2 to be visually recognized by the passenger 7 of the vehicle. The distance from the passenger to the virtual image is adjusted by moving the second screen 21 along an optical path, and the second projection lens 17 is moved along with movement of the second screen 21 such that the focal point of the visual image projected from the second projection lens 17 is adjusted on the second screen 21.
