  • Patent number: 5838097
    Abstract: An image display apparatus comprises a plurality of electron-emitting devices and an image-forming member for forming an image upon irradiation of electron beams emitted from the electron-emitting devices. The apparatus further comprises a plurality of substrates having the electron-emitting devices arrayed thereon and being arranged side by side, and a deviating unit for deviating the electron beams emitted from the electron-emitting devices arrayed on the substrates. The deviating unit deviates the electron beams toward the boundary between the substrates. When the plurality of substrates are combined with each other to provide the image forming apparatus having a large-sized screen, a display incapable region is prevented from appearing at the boundary between the substrates.
