Reflecting three-dimensional display system

A thee-dimensional display system comprising:

• an image providing device which provides elemental images;
• an image displaying device which displays the elemental images;
• a projective lens system which is aligned along the same axis as the image display device and projects the elemental images;
• a concave mirror array which is aligned along the same axis as the projective lens system, includes at least one or more concave mirrors, and said concave mirror array comprising a plurality of concave mirrors arranged in a matrix, and wherein said concave mirror array forms three-dimensional image by reflecting and integrating the projected elemental images;
• and
• a concave mirror array plane of said concave mirror array is flat or curved according to the direction or distance of projection of elemental images.
