There is now provided a television cathode ray tube having a faceplate, an electron gun means, and a glass funnel to configure the cathode ray tube as a wide-angle, shallow-depth, implosion-resistant television cathode ray tube. The glass funnel has a solder edge, a funnel throat, a parabolic area and a funnel body and the external contour between the solder edge and the parabolic area along a first section which is defined by the direction of the diagonal of the television glass funnel is essentially a steeply descending straight line, along a second section which is defined by the direction of the major axis of the television glass funnel, is essentially a flat descending straight line, which descends steeply in a curve in the area of the solder edge, and along a third section which is defined by the direction of the small axis of the television glass funnel, is essentially a steeply descending straight line. The glass funnel is configured to minimize the height of the television cathode ray tube to position said deflection coil arrangement at a distance from the shadow mask to minimize errors of electron beams, to minimize the weight of the television cathode ray tube, and to minimize risk of implosion.
