Claims (1)
電極によつて加速・制御し、上面に蛍光体層の被
着された陽極に該電子を射突させることによつて
前記蛍光体層を発光させて表示を行う蛍光表示管
において、前記制御電極を保持する枠部に貫通溝
が設けられ、前記貫通溝近傍の枠部からリード部
が延設されたことを特徴とする蛍光表示管。 Electrons emitted from the filamentary cathode are accelerated and controlled by a control electrode, and the electrons are caused to strike an anode on which a phosphor layer is deposited, thereby causing the phosphor layer to emit light and display. What is claimed is: 1. A fluorescent display tube in which a through groove is provided in a frame portion holding the control electrode, and a lead portion extends from the frame portion in the vicinity of the through groove.
