ABSTRACT:
A projection type display apparatus for displaying an enlarged composite image being composed of images each of which is produced upon a plurality of light valves upon a screen in every independent primary color. A correcting lens which corrects a projection magnification factor of the image formed by the light valve is disposed in the vicinity of at least one light valve on the projecting lens system side. The correcting lens adjusts the projection magnification factor of the image in each primary color to a predetermined factor. With this result, the disparity of pixels among the primary colors due to the chromatic aberration of magnification is corrected, and it becomes possible to obtain a high quality projection image.
