ABSTRACT:
To contrive a reduction in the overall size of the device in the case of arranging at least two screens, to reduce color shading of a 3-dimensional image, and thereby to give a further absorbedness feeling to the viewer. A 3-dimensional image display device includes a space partitioned by a frame assembled in a box shape, the space accommodating a plurality of viewers, three screens disposed so as to partition the space, three projectors disposed correspondingly to the screens, respectively, and a controller for supplying image data to the projectors and further includes a phase plate disposed between the first projector and the front screen, and further, a phase plate disposed between the third projector and a reflective mirror member.
