Abstract
A glass panel for an implosion-protected type cathode ray tube is provided with a compressive stress of 7 MPa-30 MPa in an outer surface of a face portion and a relation of R.sub.b.gtoreq.0.017D+4.0 between the radius of curvature R.sub.b of an outer surface of a blend R portion 9 in a diagonal portion of the glass panel and the largest outer diameter D of the glass panel Further, when the face portion is substantially flat, there is a relation of T.sub.r.ltoreq.0.014D+11.0 wherein T.sub.r is the largest wall thickness of the blend R portion.
