A three-dimensional display device includes a liquid crystal display which has an image display surface which emits display light, a plurality of optical fibers, each of the optical fibers having a light-receiving end which receives the display light emitted from the image display surface and an emitting end which emits the display light, and a rotation device which rotates the optical fibers around a rotation axis perpendicular to the image display surface. The rotation radius of the light-receiving end and the rotation path of the emitting end of each of the optical fibers are set to have a one-to-one relationship.
