PROBLEM TO BE SOLVED: To provide an infinity view display device which cap display a real image and is free of the risk that a decrease in eyesight is caused by achieving infinity view and to provide an infinity view planetarium device capable of displaying a real stellar image similar to a starry sky. SOLUTION: The infinity view display device includes a plurality of infinity view display units 3 which project pieces of diffused luminous flux from respective points on spatial optical modulators 1 as parallel luminous flux through convex lens optical systems 2; and those infinity view display units 3 are arrayed in parallel and the different spatial optical modulating elements 1 project the pieces of luminous flux from the mutually corresponding points in parallel. The infinity view planetarium device is constituted by arraying the plurality of infinity view display units 3 in a dome shape at a ceiling part in an observation room 5, and different stellar image original plates 1 project pieces of luminous flux from corresponding stellar images S1 in parallel to one another.
