Abstract
A glass panel for use in a cathode ray tube includes a face portion for displaying images; a skirt portion extending from a periphery of the face portion backwards; and a blend radius portion for connecting the face portion and the skirt portion. The face portion is provided with an effective screen and a wedge portion positioned near a periphery portion of the effective screen. Compressive stress layers are formed on any regions of an inside and an outside surface of the face portion and the skirt portion, and a maximum compressive stress value σFmax of the face portion and a minimum compressive stress value σSmin of the skirt portion satisfy a relationship of σSmin/σFmax<0.5.
