An image projection apparatus including a light source for emitting a plurality of monochromatic color beams having different wave lengths; a first light transmit unit; a light switch unit having a plurality of mirrors for selectively deflecting the monochromatic color beams at a predetermined angle; a quadrangular beam generating unit for converting the reflected monochromatic color beams into quadrangular beams having certain ratios of length to height; a panel for receiving the converted quadrangular beams and forming a monochromatic color bar on at least one portion of upper, mid, and lower portions thereof; and a projection lens unit disposed opposite to the panel. Accordingly, by using the light switches, a monochromatic color bar is formed on single panel with the same utilization efficiency of light as that of three panels, thereby embodying a high image quality.
