Abstract
Disclosed is a three-dimensional display device which includes a pixel array and a lens array. The pixel array includes a plurality of sub-pixel units. The lens array includes a plurality of lenses. Each lens includes a center face, an incident face, a first light emergent face and a second light emergent face, wherein the first light emergent face and the second light emergent face are in face symmetry relative to the center face and are different in centers of curvature. In the same lens, the incident face receives light sent by the N sub-pixel units, and the first light emergent face and the second light emergent face emit light received by the incident face so that a plurality of viewpoints are formed at a viewpoint end, wherein N is larger than or equal to 4 and is an integer. Because light emitted by the first light emergent face and the second light emergent face is arrayed in a staggered manner, the curvature of the lens array is larger than that of a common lens array with non-staggered array and thus the focal distance is comparatively small. Therefore, the three-dimensional display device has a thinning design.
