Abstract
A three-dimensional (3D) image display apparatus is provided. The apparatus includes a plurality of light sources; a spatial light modulator configured to modulate light from the plurality of light sources according to 3D image information; and a focusing optical system configured to focus an image formed by the spatial light modulator onto a focal plane. The plurality of light sources may be arranged such that multiple focal points, respectively corresponding to the plurality of light sources, are formed on the focal plane near a pupil of a user.
