Abstract
A complex spatial light modulator for modulating a phase and amplitude of a light beam and a 3-dimensional (3D) display including the same are provided. The complex spatial light modulator includes a spatial light modulator modulating a phase of a light beam, a lenticular lens array disposed next to the spatial light modulator, and a volume holographic lens array spaced apart from the lenticular lens array and allowing light beams output from the lenticular lens array to be superimposed and to interfere with each other, and so that the phase and an amplitude of the light beam are simultaneously modulated.
