The present invention provides a reflection-type three-dimensional display system. The present invention comprises an image providing device that provides elemental images; an image displaying device that displays the elemental images; a projective lens system that is located along the same axis as the image providing device; and a concave mirror array that is located along the same axis as the projective lens system. The projective lens system projects the image that is displayed by the image displaying device to the concave mirror array, and the concave mirror array reflects and integrates the projected image and therefore displays the three-dimensional image.
