ABSTRACT:
In a glass front-panel for a cathode ray tube, whose surface layer contains more potassium ions than those in the interior thereof, and whose flange is stuck to a rear panel to form a vacuum vessel, only the surface layer of the flange portion is substantially removed, or in a glass front-panel for a cathode ray tube, comprising an image displaying portion, a side wall portion and a flange portion, a belt-like electrode for making a gradient of electric potential easier is disposed on a surface of the side wall portion, so that the cathode ray tube is prevented from being damaged due to dielectric breakdown.
