ABSTRACT:
A cathode ray tube is constructed such that a resistance of a first conductive element connected to a metal film on the inner side of the panel is lower than a resistance of a second conductive element connected to a shadow mask. Thus, the amount of electrons which are emitted from an electron gun to strike the metal film increases, to thereby enhance luminance, and the amount of electrons striking the shadow mask is decreased, to thereby reduce thermal deformation of the shadow mask.
