Abstract
An image display apparatus is provided for enlarging and projecting a light emitted from a plurality of self-emitting elements on a screen by beam scanning means, which is an image display apparatus having little or no luminance unevenness by solving the conventional problem of causing luminance unevenness in images projected on the screen due to a variance in luminance characteristics of each self-emitting element. It is configured such that a part of the light scanned on the screen from the beam scanning means is provided to a photodetector element that converts the intensity of the light into an electric signal so as to correct a driving signal to be supplied to the self-emitting element by the intensity of the light detected by this photodetector element.
