ABSTRACT:
A color picture tube in which an electron gun emits three electron beams arranged in line, in which the diameter of the spot (26) at the center of the screen in the in-line direction is smaller than that in the direction perpendicular to the in-line direction when the spot is in a just-focused state. Therefore the shape of the spot (27) at the periphery of the screen is generally a true circle. As a result, the resolution at the periphery of the phosphor screen is improved, and the more is suppressed.
