The display 25 displays an image captured by the right rear camera that captures the situation on the right rear of the vehicle. That is, the display 25 displays an image of the electronic mirror functioning as the right side mirror. In addition, when another vehicle is approaching from the right rear of the vehicle, the display 25 displays a right rear approaching image to that effect.

As described above, the surface of the reflecting mirror 3 is formed to be curved. Therefore, as shown in FIG. 4, the reflecting mirror 3 reflects the display light DL that forms the display images DG1, DG2, DG3, DG4, and DG5 displayed by the organic EL displays 11, 12, 13, 14, and 15. The virtual images VI1, VI2, VI3, VI4, and VI5 visually recognized by the vehicle occupants are distorted with respect to the display images DG1, DG2, DG3, DG4, and DG5, respectively.

Therefore, as shown in FIG. 5, the displays 21, 22, 23, 24, and 25 display corrected display images CG1, CG2, and CG3 corrected to cancel the distortion of the virtual images VI1, VI2, VI3, VI4, and VI5, respectively. , CG4 and CG5.

Therefore, the reflecting mirror 3 reflects the display light DL that forms the corrected display images CG1, CG2, CG3, CG4, and CG5 displayed by the displays 21, 22, 23, 24, and 25, so that as shown in FIG. At the same time, non-distorted virtual images VI11, VI12, VI13, VI14, and VI15 are viewed by vehicle occupants.

The display device 1 configured as described above includes organic EL displays 11 , 12 , 13 , 14 and 15 and a reflector 3 . The organic EL displays 11 to 15 emit display light DL representing an image to be displayed from the display screen. Reflector 3 reflects display light DL emitted from organic EL displays 11-15.

The display screens of the organic EL displays 11 to 15 face downward on the lower surface LS of the meter hood MF which is installed in the vehicle compartment and protrudes from the front to the rear of the vehicle. installed. The reflecting mirror 3 is disposed below the organic EL displays 11 to 15 with its reflecting surface reflecting the display light DL obliquely tilted with respect to the irradiation direction of the display light DL.

In this way, the display device 1 reflects the display light DL emitted from the organic EL displays 11 to 15 by the reflecting mirror 3 and irradiates it into the vehicle interior. As a result, a virtual image is projected onto the reflecting mirror 3, and the occupant in the vehicle can visually recognize this virtual image. In this manner, the display device 1 does not allow passengers in the vehicle to directly view the organic EL displays 11 to 15 arranged with a step between the organic EL displays. That is, by reflecting the display light DL on the reflecting surface of the reflecting mirror 3, the display device 1 displays a plurality of display images on the organic EL displays 11 to 15 in a state in which there is no level difference between the display images. can be displayed with Therefore, the display device 1 can make it difficult to see the joint between two adjacent organic EL displays in the virtual image visually recognized by the passenger.

Further, since the display device 1 can make the joints between the organic EL displays difficult to see as described above, it is possible to eliminate the need for optical bonding. Furthermore, since the display device 1 does not allow the passengers in the vehicle to directly view the organic EL displays 11 to 15 as described above, anti-glare processing and anti-reflection processing can be eliminated.

Since the organic EL displays 11 to 15 emit light from the organic EL elements themselves, they do not require a backlight unlike liquid crystal displays. Therefore, the organic EL displays 11 to 15 can display a deep black image by stopping the light emission of the organic EL elements. On the other hand, in a liquid crystal display, light from the backlight slightly leaks through the black portions of the displayed image, so the black portions of the image appear whitish.

Therefore, in the display screens of the organic EL displays 11 to 15, the display device 1 displays, in black, at least the portion around the joint between the two adjacent organic EL displays, so that the two organic EL displays are displayed. The seams between them can be made even more difficult to see.

In the embodiment described above, the organic EL displays 11 to 15 correspond to the display section, the reflecting mirror 3 corresponds to the reflecting section, and the meter hood MF corresponds to the canopy member.
