An aerial image projector includes a first reflective element, a second reflective element, a first optical element, a first display device, and a second display device. The first reflective element transmits, in a second direction, a part of first image light traveling in a first direction, reflects, in a third direction, a part of second image light traveling in the second direction, and transmits, in the third direction, a part of third image light traveling in a fourth direction. The second reflective element retroreflects the first image light transmitted through the first reflective element as the second image light. The first optical element is between the first reflective element and the second reflective element and collects the first image light and the second image light. The first display device emits the first image light. The second display device emits the third image light.
