PROBLEM TO BE SOLVED: To provide an in-vehicle projection display device capable of providing a display image with a sense of perspective that matches outside scenery seen at a position overlapping or adjacent to the display image while suppressing an increase in cost of the device.SOLUTION: An image plane 22 of a virtual image 21 displayed by an HUD device is placed at an angle with a plane perpendicular to a direction of a line of sight 18 connecting an eye point EP and the virtual image. As this arrangement actually provides the planar virtual image 21 with a sense of depth and perspective, there is no need to display a stereoscopic image. A two-dimensional display panel 11 is disposed at an angle with a Y-axis, and exit light 13 is output in a Z direction that is at an angle with an axis perpendicular to a surface of the two-dimensional display panel 11.SELECTED DRAWING: Figure 1

    【課題】装置のコスト上昇を抑制しつつ、表示像と重なった位置若しくは隣接する位置に映る車外の風景に合わせた遠近感を形成することが可能な車両用投影表示装置を提供する。【解決手段】HUD装置により表示される虚像21の結像面22が、アイポイントEPと前記虚像とを結ぶ視線18の方向と直交する面に対して傾斜した状態で配置されている。平面的な虚像21であっても実際に奥行きや遠近感が得られるので、立体像を表示する必要がない。二次元表示パネル11をY軸に対して傾斜した状態で配置すると共に、二次元表示パネル11の面と直交する軸に対して傾斜したZ方向に出射光13を出射する。【選択図】図1
