ABSTRACT:
An image display apparatus which includes at least one light source to generate and radiate a light beam, a color separating unit to separate the light beam emitted from the light source into a plurality of color light beams and make at least one of the separated color light beams and the other color light have different polarizations. Further, a plurality of light valves are used to form an image by controlling at least one of the color light beams separated by the color separating unit and emitted therefrom, in the unit of pixel according to input image signals. Additionally, an image combiner is used to combine images generated by the light valves.
