Summary:PURPOSE: A deflection yoke for a CRT is provided to prevent distortion distribution at the top and bottom of center axis in a deflection yoke. CONSTITUTION: A CRT comprises a panel having a phosphor surface, a funnel, an electron gun, and a deflection yoke. The deflection yoke includes a horizontal/vertical deflection coil(231) for deflecting horizontally and vertically electron beams emitted from the electron gun; a ferrite core(234) for reducing the loss of magnetic force generated from the deflection coils; and a holder(232) for fixing the deflection coils and the ferrite core and insulating the horizontal deflection coil from the vertical deflection coil. A phosphor side aperture section of the horizontal/vertical deflection coils is square shape. The distribution of the horizontal deflection coil is in the range of 45 angles around the center of the horizontal axis.
