a scanning projector; and

a screen,

wherein, the scanning projector includes a high-speed two-dimensional scanning element which performs scanning of a convergent light in a horizontal direction and a vertical direction,

the screen is formed in a shape formed by cutting out a part of a sphere around a rotation axis of the scanning element, and the screen is positioned such that the rotation axis of the scanning element is at a center of the part of the sphere, and

the distance between the rotation axis and respective locations in the direction of the scanning is determined such that the convergent light is focused on the screen.
