Cathode-ray tube

A cathode-ray tube comprising:

• a glass panel section constituting a glass envelope having a tube axis, said glass panel section including a substantially rectangular faceplate, whose inner and outer surfaces are curved, and a skirt extending from a peripheral portion of said faceplate along the tube axis, wherein when ts, tl and td respectively denote thickness of said faceplate in the vicinity of the center portion of the short side, that in the vicinity of the center portion of the long side and that in the vicinity of the corner, and Hs, Hl and Hd respectively represent length of the skirt at the center portion of the short side, that at the center portion of the long side and that at the corner as the length of each of them is measured between the outer surface of said faceplate and the end portion of said skirt along the tube axis, then, the thickness of said faceplate and the length of said skirt have relations defined by the following equations of inequalities (1) and (2):
• Hs.gtoreq.Hd and Hl.gtoreq.Hd (1),
• tl.gtoreq.ts and td.gtoreq.ts (2).
