In another example, the rearview mirror 25 may be used as the third display device of the vehicle image display system 1 to display an image from the radar sensor 20 or the center rear camera thereon. In this case, since the center auxiliary display area 32c can be eliminated, it is possible to enlarge the main display area 31 by the amount thereof or to enlarge the view area of the front windshield 15 that is not used as the first display device 3.
