Abstract:
1. A stereoscopic two-dimensional image display device comprising: a display unit including an image display plane on which an image is displayed; an image transfer panel arranged apart from the image display plane, for imaging light emitted from the image display plane on an imaging plane in a space, thereby displaying a stereoscopic two-dimensional image; and an optical path changing member arranged between the image display plane and the imaging plane, for changing the optical path of the light emitted from the peripheral edge having a predetermined region constituting the image display plane, wherein the stereoscopic two dimensional image which is individually visible is displayed on the imaging plane of the peripheral edge formed through the optical path changing member and the imaging plane except the peripheral edge, and a mark serving as an image for guidance is displayed in the peripheral edge in at least its right and left position with respect to a central region; wherein the optical path changing member is a prism sheet having an arrangement of a plurality of prisms located in the vicinity of the front surface or rear surface of the image transfer panel and bends the light emitted from the peripheral edge toward the center of the image plane.
