Abstract:
1. An image display apparatus comprising: a first substrate including an image display surface which has a plurality of phosphor layers and black-colored layers extending in an X-direction; a second substrate opposing the first substrate with a space therebetween, and including a plurality of electron sources arranged at a predetermined pixel pitch in the X-direction and a Y-direction perpendicular to the X-direction, the electron sources activating the phosphor layers; and a plurality of columnar spacers provided between the first substrate and the second substrate and defining the space therebetween, the spacers being arranged to oppose the black-colored layers; the plurality of spacers being arranged at several times the pixel pitch in the X-direction, and arranged in the Y-direction at the same pitch as the pixel pitch at least in a part of the image display surface, those of the spacers arranged in the Y-direction at least in the part of the image display surface being arranged in line with the electron sources and being located at both sides of each of the corresponding electron sources to make an electron emitted from each of the corresponding electron sources pass between each adjacent pair of said those spacers.
