Abstract
A projection-type image display apparatus having a structure adapted so that the efficiency of the use of light and resolving power thereof can be enhanced. The projection-type image display apparatus includes a light source; a color separation unit separating incident rays according to predetermined wavelengths, and directing the separated rays at different angles; a lens array dividing the rays separated by the color separation unit into predetermined pixels; a driving portion driving the lens array to change the proceeding paths of the color rays; a polarizing beam splitter changing a proceeding path of incident rays depending on a direction of polarization; a reflection-type display device producing a color image using the rays entering via the polarizing beam splitter, and reflecting the color image toward the polarizing beam splitter; and a projection lens unit magnifying and projecting an incident image onto a screen. In addition, the projection-type image display apparatus may comprise. Alternative designs include a transmission-type display device in place of the reflection-type display device and a deflector changing the proceeding paths of the individual color rays separated by the color separation unit instead of the driving portion.
