description PURPOSE:To prevent any deformation in each of electron-beam control electrodes due to heat generated when a current is applied to a linear hot- cathode by interposing stepped insulating-spacers between the electron-beam control electrodes, and therefore forming gaps between the electron-beam control electrodes and the stepped insulating-spacers. CONSTITUTION:A plurality of metallic pins 1a are fixed to a fence-like electron- beam control electrode 8e arranged opposite to a phosphor 11, planar insulating- spacers 5, electron-beam control electrodes 8d to 8a and stepped insulating- spacers 6c to 6a or 7b to 7a are alternately inserted between the pins. Even if the end part of the metallic pin 1a is fused and fixed by application of a laser beam after a fixing insulating-spacer 4a or 4b is arranged, there is no fixing force exerted upon each of the electron-beam control electrodes 8a to 8d. Thus a gap is formed between each of the electron-beam control electrodes 8a to 8d and each of the stepped insulating-spacers, so that an electrode unit wherein no thermal-expansion deformation is caused to each of the electron- beam control electrodes 8a to 8d may be obtained.
