第２表示像は、自車両又は他車両を表した車両図形であり、
目視者の視野内に配置され、奥行方向に長さを有した実像（４５Ａ、４５Ｂ）を表示する実像表示部（４Ａ、４Ｂ）を、備え、
実像表示部は、自車両において目視者から見た第１表示像の虚像より手前側に、当該虚像との連続性を有した標示図形の実像を、表示する表示装置である。
Is been inventions disclosed in order to solve the above problems,
A light emitting section (3A, 3B) that emits light of a display image (39A, 39B) ;
An optical path forming section (120, 101) for guiding light from the light emitting section to form a display optical path (143), and a display device mounted on the host vehicle,
A first light emitting unit as a light emitting unit that emits light of a first display image as a display image;
A second light emitting unit (7) that emits light of a second display image (70) different from the first display image,
The optical path forming unit guides light from the first light emitting unit to form a first display optical path as a display optical path, guides light from the second light emitting unit to form a second display optical path (147),
The virtual image forming members (2, 105) disposed in the visual field of the viewer (200) and on the first display optical path and the second display optical path allow light from the first light emitting unit and the second light emitting unit to be viewed by the viewer. of by reflecting on the side, the first display image of the virtual image (35A, 35B) forward and is imaged virtual image (71) of the second display image,
The virtual image of the first display image is formed in the depth direction viewed from the viewer to form an oblique image surface (145) that is inclined with respect to the optical axis (144) of the display optical path ,
The depth of the image plane on which the virtual image of the second display image is formed is smaller than the depth of the image plane on which the virtual image of the first display image is formed,
The first display image is a marking figure representing a road marking that divides the traveling lane of the host vehicle.
The second display image is a vehicle figure representing the host vehicle or another vehicle,
A real image display unit (4A, 4B) for displaying a real image (45A, 45B) arranged in the visual field of the viewer and having a length in the depth direction;
The real image display unit is a display device that displays a real image of a sign figure having continuity with the virtual image on the near side of the virtual image of the first display image viewed from the viewer in the host vehicle .
このような発明によれば、表示像の正面視形状をそのまま虚像表示するのではなく、奥行き方向に寝かせた結像により表示像の虚像表示を、発光部からの表示光路の光軸に対して斜めに傾かせることとなる。すなわち、現実空間の奥行方向に長さを有した虚像表示が行われ得るので、従来の疑似的な奥行き表現に比べて、奥行き感を出すことが可能となる。 According to such inventions, rather than as a virtual image display viewed from the front shape of the display image, a virtual image display of the display image by the imaging to lay in the depth direction, with respect to the optical axis of the display optical path from the light emitting portion Will be tilted diagonally. That is, since a virtual image display having a length in the depth direction of the real space can be performed, a sense of depth can be obtained as compared with the conventional pseudo depth expression.
