Abstract

PURPOSE:To improve convergence with simple structure by providing at least a pair of magnetic substances which are opposed to each top of a rectangular panel from the vicinity of a vertical deflection coil and stretched beyond the panel side end face of a deflection yoke. CONSTITUTION:Deflection yokes 42a and 42b are mounted on an enclosure 1. Magnetic substances 91a, 91b, 92a, 92b, 92c, and 92d are privided, while being opposed to each top of a rectangular panel from the vicinity of a vertical deflection coil and stretched beyond the panel side end face of the deflection yokes 42a and 42b. The magnetic field distribution toward the pincushion magnetic field gradually increases its intensity from the root of the magnetic substances 92a, 92b, 92c, and 92d to the panel sides in the axial direction and shows the maximum intensity near the tip section on the panel sides of the magnetic substances 92a, 92b, 92c, and 92d.
