Abstract
A cathode-ray tube in which outer convergence plates as constituents of the convergence plate assembly in the electron gun are supplied with individual voltages so that the horizontal misconvergence at the center portion and at the peripheral portions of the screen are positively corrected and in the arrangement the anode button is provided with a plurality of voltage supply pins. Further, the end portions of the two lead wires which are introduced form the anode button are opened outwardly so that the lead wires are prevented from coming in contact with the bead glass.
