Provided is a head-up display device that that, while preventing the occurrence of speckle noise, enables the generation of a high-quality video as a virtual image. From a projector (4) using an LED light source, videos respectively traversing a first projection lens (16) and a second projection lens (17) are projected to a first screen (20) and a second screen (21), and by means of the videos projected to the first screen (20) and second screen (21) being reflected to the front window (6) of a vehicle (2) and being caused to be viewed by a vehicle occupant (7), a virtual image of the video viewed by the vehicle occupant (7) is generated. Also, the present invention is configured in a manner so as to adjust the distance from the occupant to the virtual image by means of moving the second screen (21), and to cause the movement of the second projection lens (17) alongside the movement of the second screen (21) in a manner so that the video projected from the second projection lens (17) is focused on the second screen (21). |
