Abstract
A technique is described for lightening a shadow of a damper line for preventing vibration of a color selecting member cast on a video screen and further preventing occurrence of the shadow. In a cathode ray tube in which electron beams emitted from neighboring electron guns cross each other before passing through a plurality of apertures of a color selecting member and has an area through which both of the electron beams pass. A damper line is provided in the area through which both of the electron beams pass. Since one of the electron beam falls on a shadow cast by the other electron beam, the shadow becomes lighter.
