Abstract
The present invention intends to provide a cathode ray tube capable of preventing a rise in temperature of the deflection yoke efficiently, without increasing the size of a display device.To do so, in the cathode ray tube of the invention, a part of a heat radiator, which is made up of filaments, is attached to a cone part of a horizontal deflection coil so that heat is exchanged between the heat radiator and the horizontal deflection coil, while the other part of the heat radiator extends outside of the deflection yoke. The heat radiator is formed from a plurality of copper wires arranged in parallel to each other in the form of a strip. The copper wires are 0.24 mm in diameter and coated with insulation.
