写用陰極線管。A mesh-like or blind-like conductive member is arranged along the outer surface of a face plate having a fluorescent surface on the inner surface so as not to impair the quality of the image drawn on the effective scanning surface of the fluorescent surface. In the projection cathode ray tube, a peripheral edge of the conductive member corresponding to outside the effective scanning plane is arranged to be thermally separated from the faceplate surface, and a peripheral edge of the conductive member is arranged outside the faceplate. A projection cathode ray tube characterized in that it is thermally and electrically connected to a disposed heat dissipation structure.
