A cathode ray tube display which can reduce the temperature rise of its deflection yoke, not by using either extra-fine wires or litz wires but by increasing the heat radiation of its saddle-type coils, is provided. A deflection yoke arranged in the rear periphery of a cathode ray tube display main body includes a saddle-type horizontal deflection coil, an insulating frame located outside of the saddle-type horizontal deflection coil, a saddle-type vertical deflection coil and a ferrite core located outside the insulating frame. The surface of the saddle-type horizontal deflection coil is partially exposed from the screen-side end face of the ferrite core toward the screen, and the surface area of the exposed part is predetermined to be from 100 to 298 cm.sup.2. Similarly, the exposed surface area of the saddle-type vertical deflection coil is predetermined to be from 55 to 185 cm.sup.2.
