Abstract
A projection display includes three integrator modules which emit red, green, and blue beams, respectively. The integrator modules include at least one compact light source and a glass rod that transforms a light beam emitted from the at least one compact light source so as to have a uniform light intensity and emits a modulated light beam. The glass rod includes an incident portion through which the light beam radiates, and an emission portion through which the light beam is emitted. The incident portion includes a parabolic first reflective surface to collimate the light beam radiating from the at least one compact light source, and the at least one compact light source is located in the vicinity of a focal point of the first reflective surface.
