Abstract: This invention relates to a cathode ray tube having a funnel in the shape of a reverse curvature designed to improve the strength for the glass manufacturing process and test specification. In the present invention, a reverse radius is applied to the whole of the rear-side glass, which is the funnel, of the cathode ray tube. Therefore, the cathode ray tube has a high degree of strength for vacuum and a low weight, so that it can have a wide angle of the electric beam in accordance with the enlargement and the flattening plane of the cathode ray tube. The cathode ray tube that has the funnel in the shape of the reverse curvature comprises: a yoke on which a deflection coil is placed; and a body part that extends from the yoke toward an opening terminal attached to the panel. The center of a curvature in the yoke is located outside of the cathode ray tube; the center of a curvature in the body part extending from the yoke is located outside of the cathode ray tube; and the center of the curvature in the vicinity of the opening terminal of the body part is located inside of the cathode ray tube. Therefore, an inflection point is located in the body part in the vicinity of the opening terminal.
