PROBLEM TO BE SOLVED: To provide an in-vehicle projection display device capable of displaying an image with a sense of perspective and depth and of preventing a reduction in visibility while suppressing an increase in cost of the device.SOLUTION: An in-vehicle projection display device has a first image plane 22(1) and a second image plane 22(2) as image planes for virtual images, the first imaging plane being placed substantially parallel to a plane perpendicular to a direction of a line of sight 18 connecting an eye point and a virtual image and the second imaging plane being placed at an angle with the plane perpendicular to the direction of the line of sight 18 connecting the eye point and the virtual image. Information for which visibility is critical is presented as a planar image formed on the first image plane 22(1), and an image with a sense of depth and perspective is formed on the second image plane 22(2).SELECTED DRAWING: Figure 3
【課題】装置のコスト上昇を抑制しつつ、遠近感や奥行きのある表示を可能にすると共に、視認性の低下を防止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】虚像の結像面として、第1の結像面22(1)と第2の結像面22(2)とを有し、前記第1の結像面がアイポイント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ほぼ平行に配置され、前記第2の結像面が前記アイポイント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、視認性を重視する情報を平面的な像として第1の結像面22(1)に形成し、第2の結像面22(2)には奥行きのある遠近感のある像を形成する。【選択図】図3
