Abstract (en)
[origin: EP0651423A1] In a glass front-panel (1) for a cathode ray tube (12), whose surface layer contains more potassium ions than those in the interior thereof, and whose flange (1c) is stuck to a rear panel (10) to form a vacuum vessel, the surface layer of the flange portion (1c) is substantially removed or eluted. A belt-like electrode (2) for making the gradient of electric potential smoother is disposed on a surface of the side wall portion (1b), so that the cathode ray tube (12) is prevented from being damaged due to dielectric breakdown. <IMAGE>
