PROBLEM TO BE SOLVED: To provide, at a low cost, a head-up display device that can form a plurality of virtual images respectively at positions having different distances from a driver.SOLUTION: A head-up display device comprises an intermediate image display body on which an intermediate image is formed, and a projection optical system that projects the intermediate image formed on the intermediate image display body on a display area of a projection target body. The projection on the display area performed by the projection optical system forms a virtual image on the front of a windshield of a vehicle; and the virtual image is formed as an image having a depth in the fore-and-aft direction according to at least one of the shapes of the intermediate image display body, projection target body, and projection optical system.SELECTED DRAWING: Figure 1

    【課題】運転者からの距離が異なる位置に複数の虚像をそれぞれ形成することができるヘッドアップディスプレイ装置を低コストで提供する。【解決手段】中間画像が形成される中間画像表示体と、中間画像表示体に形成された中間画像を被投影体の表示領域に投影する投影光学系とを備え、投影光学系による表示領域への投影によって車両のウインドシールドの前方に虚像が形成され、虚像は、中間画像表示体と、被投影体と、投影光学系との少なくとも1つの形状にしたがって、前後方向に奥行きを有する画像として形成される。【選択図】図1
