An image display apparatus includes an image forming unit, a projecting unit, first and second correcting units, and a driving unit. The image forming unit forms images for left and right eyes. The projecting unit emits light for the left-eye image via an optical filter for the left eye and emits light for the right-eye image via an optical filter for the right eye having properties different from those of the left-eye optical filter, to display the images in a superimposed manner. The first and second correcting units each correct image signals for the corresponding eye using correction data for use in correcting non-uniformity in the image being displayed by the light emitted via the corresponding optical filter. The driving unit drives the image forming unit on the basis of the corrected image signals to cause the image forming unit to form the left-eye image and the right-eye image.
