ABSTRACT:
A projection display includes first through third light source units to radiate first through third light beams, respectively, having different colors, an X-cube prism to combine paths of the first through third light beams, an optical modulator to sequentially modulate the first through third light beams according to image information, and a projection lens unit to magnify and project the modulated light beams onto a screen. Each of the first through third light source units includes at least one optical module. The optical module includes a collimator having a first reflective surface in a parabolic shape, and a compact light source located in the vicinity of a focal point of the first reflective surface.
