Abstract
A cathode ray tube includes a panel with inner and outer surfaces, a funnel connected to the panel, a neck connected to the rear of the funnel, and a shadow mask mounted within the panel. The inner surface of the panel satisfies the following condition:0.2≦Px≦0.4, 0.3≦Py≦0.6where when the inner surface of the panel is expressed by the following biquadratic: based on the central point of the inner surface of the panel with the three-dimensional orthogonal coordinates system defined by the x, y and z axes, Px and Py are defined by the following formula:
