Abstract
The present invention relates to an image display apparatus for forming an image with a plurality of luminescent spots to be precisely aligned in a matrix. For example, a spacer disposed between an electron source and a face plate causes luminescent spots on the face plate spaced unevenly. The luminescent spots spaced unevenly will produce a visual unevenness in luminance which deteriorates the quality of produced image. By modifying the quantity of light of luminescent spots spaced unevenly, the visual unevenness in luminance is compensated.
