  • Publication number: 20070247058
    Abstract: The present invention suppresses color irregularities or a black spot defect by reducing mislanding of electron beams or the generation of discharge at end portions of a spacer. The spacer is arranged on scanning lines as a single member having no split portions, and the spacer has both end portions thereof positioned exceeding both sides of a display region in the lateral direction (x direction) formed of a two-dimensional arrangement of electron sources and phosphors. An anode is formed to cover a display region with a width exceeding a width of the display region in the extending direction of the scanning lines. Both end portions of the spacer in the lateral direction (x direction) are arranged at positions retracted from a width of the anode. In the lateral direction, a relationship of the width of the display region<the width of the spacer<the width of the anode is established. The phosphors are applied to stripe-like black matrix apertures which extend in the vertical direction (y direction).
