In this case, the guide plates 230 and 330 are formed of a light transmissive resin, and the light source unit 90 illuminates the guide plates 230 and 330 by irradiating the guide plates 230 and 330 with light under the control of the control unit 100. Let
Further, a light transmitting member may be disposed on the upper surface of the guide plate 230 in the third and fourth embodiments, and the light transmitting member may be turned on. Furthermore, a display unit similar to the first display unit 10 may be provided on the upper surface of the guide plate 230.

  In the third embodiment, the guide plate 230 may be integrated with a visor that covers the periphery of the display device 1.

  In each said embodiment, although the 1st display part 10 was provided with the display panel 11 and the backlight 12, it may not be restricted to this but an organic electroluminescent display (OELD: Organic Electro-Luminescence Display) may be provided. In addition, a pointer instrument including a pointer, a motor for rotating the pointer, and a dial on which a scale is formed may be provided.

In the first embodiment, the guide frame 30 is formed in an arch shape. However, the guide frame 30 is not limited to this, and may be formed in a gate shape in which one side of the square is omitted when viewed from the viewer.
The guide frame 30 may have a frame shape that surrounds the periphery of the aerial image plane 50 as well as below the aerial image plane 50.

  In the first and second embodiments, the guide frames 30 and 130 are made of a light transmissive resin. However, the guide frames 30 and 130 may be made of glass or the like other than the resin as long as they have light transmissive properties.

  In the above embodiments, the aerial image plane 50 extends along the same direction as the display surface 15, but may extend along a direction different from the display surface 15.
