ABSTRACT:
A cathode ray tube having a panel with a fluorescent film made of a fluorescent material coated at the inner surface thereof; a cathode mounted in the panel and generating an electron beam; an electron beam controller for controlling and deflecting the electron beam in order to hit the fluorescent film; and a back glass attached to the panel and sealed in a state that the cathode and the electron beam controller are mounted therein, in which a ratio of a minimum thickness of a panel glass to a minimum thickness of a skirt portion of the panel is below 1.0. The full depth of the cathode ray tube is reduced and the weight of the cathode ray tube is minimized by controlling the thickness of the panel glass, the skirt portion of the panel glass and the back glass. In addition, the atmospheric pressure applied to the panel glass and the back glass is uniformly distributed to the panel glass, the back glass and the skirt portion, thereby performing a deformation.
