Abstract
PURPOSE: To prevent the color shear of pictures through thermal expansion by providing a film of a material with high electron beam reflectivity on the electron beam incident surface of a color selecting electrode to reduce the temperature increase of the color selecting electrode during operation.
CONSTITUTION: A fluorescent screen 5 comprising three kinds of phosphor stripes is provided on the inside surface of the transparent front glass plate 4 of a color Braun tube, a color selecting electrode is formed with a shadow mask 3 provided with many holes 3a on the screen, and an electron beam reflecting film of a material with high electron beam reflectivity is provided on the electron beam incident surface of the shadow mask 3. Thus the most of energy of the incident electron beam is removed in the form of kinetic energy of the reflected electron beam to reduce the temperature increase of the color selecting electrode, and the color shear of the picture due to thermal expansion can be reduced.
