Disclosed is a three-dimensional image forming screen in which, on the basis of a screen substrate having functions of scattering and transmission, polarizing lines for separating and transmitting left and right images from projectors are formed at one surface of the screen substrate and curved surface lines are formed at the other surface of the screen substrate to have the same direction and size as those of the polarizing lines. With this configuration, scattering and transmission of light, separation, transmission, and combination of left and right images, and expansion of the separated images are performed by the single screen, so as to achieve a wide viewing angle of the screen and to allow a viewer to watch a three-dimensional image having a high vividness without assistance of polarizing glasses. When being coupled with a rotating rod that is rotated by a motor, the three-dimensional image forming screen takes the form of a roll-up screen. Alternatively, when being coupled with a frame, the three-dimensional image forming screen can achieve a good flatness. |
