An image display apparatus which controls electron beams emitted from an electron source by electrodes having an arrangement of electron beam passage apertures and displays an image by irradiating the electron beams onto phosphors on a screen. The image display apparatus includes a means which changes at least a position of the electron beam passage aperture of a second electrode of the electrodes corresponding to the electron beam passage aperture of a first electrode of the electrodes in accordance with the position on the screen and controls the potential difference between the two electrodes, thereby making it possible to control the landing position of the electron beams on the screen.
