The image display apparatus has a liquid crystal display device (2), and an ocular lens (3) for projecting an image displayed by the liquid crystal display device (2) on a user's retina. A pair of first and second diffraction gratings (11) and (12) are provided in an optical path lying between the ocular lens (3) and an exit pupil (6) formed by the ocular lens (3). The first and second diffraction gratings (11) and (12) are arranged so that the angle of diffraction caused by the second diffraction grating (12) for each wavelength of the displayed image is approximately coincident with the angle of diffraction caused by the first diffraction grating (11).
