PROBLEM TO BE SOLVED: To provide an in-vehicle projection display device capable of providing a display image with a sense of perspective and depth, as necessary, that matches outside scenery seen at a position overlapping the display image while suppressing an increase in cost of the device.SOLUTION: An in-vehicle projection display device includes a tilt adjustment mechanism 55 for adjusting a direction of an image plane 22 of a virtual image 21 relative to a direction of an optical axis 18. When presenting a virtual image 21 with a sense of depth, the tilt adjustment mechanism 55 is adjusted such that the image plane 22 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. In order to tilt the image plane 22, the two-dimensional display panel 11 is positioned aslant, and exit light 13 of the two-dimensional display panel 11 is directed in a direction at an angle with a direction perpendicular to a surface of the two-dimensional display panel 11. Switching between the tilted state and untilted state of the image plane 22 is automatic.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に映る車外風景に合わせた遠近感や奥行きを必要に応じて形成可能な車両用投影表示装置を提供する。【解決手段】虚像21の結像面22の向きを光軸18の向きに対して調整する傾斜調整機構55、を備える。奥行きのある虚像21を表示する場合には、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るように傾斜調整機構55を調整する。結像面22を傾斜させるために、二次元表示パネル11を傾斜した状態に位置決めし、二次元表示パネル11からの出射光13は、二次元表示パネル11の面に垂直な方向に対し傾斜した方向に向ける。結像面22が傾斜した状態と傾斜しない状態とを自動的に切り替える。【選択図】図1
