This invention is a novel device that displays three-dimensional moving images featuring binocular disparity and motion parallax that can be seen simultaneously by multiple viewers in different positions without requiring headgear. This device comprises: longitudinal light-guiding members that rotate around their longitudinal axes; and light-emitting members inside, or attached to, each longitudinal light-guiding member. Changes in the content of light rays from the light-emitting members are coordinated with changes in the directions of these light rays so that viewers in different positions can see appropriate three-dimensional images. Advantageous features include: no headgear required, allows multiple viewers, high image resolution, avoids pseudoscopic images, offers wide viewing range, scalable to large size displays, multi-directional motion parallax, high light efficiency, avoids head tracking, avoids reciprocal motion, avoids fluid lag, avoids ghost-like images, and avoids use of coherent light.

I claim: 1. A device for displaying three-dimensional images, comprising:a plurality of longitudinal light-guiding members that rotate around their longitudinal axes,a plurality of light-emitting members inside each longitudinal light-guiding member, wherein light rays from light-emitting members are guided through light-transmitting portions of the longitudinal light-guiding member so that the directions of the light rays change as the longitudinal light-guiding member rotates; and wherein changes in the content of light rays from the light-emitting members are coordinated with changes in the directions of those light rays to create three-dimensional images.
