Abstract

PURPOSE:To obtain an excellent image with no brightness irregularity by providing a plate-shaped guiding device restricting the position of a cathode electrode with tension along a back electrode independently from an insulating spacer restricting the relative position between the back electrode and an electron beam extracting electrode. CONSTITUTION:Insulating spacers inserted between a back electrode 4 and an electron beam extracting electrode 5 are integrated into a sheet of insulating spacer 19, a plate-shaped guiding device 22 applied with tension by a plate spring stuck with support pins fixed on both sides of an insulating holder 15 respectively is arranged in contact with the front face of the back electrode 4. This plate-shaped guiding device 22 is bored with multiple rectangular through holes 22a penetrated by the insulating spacer 19, multiple through holes 22b bored continuously in parallel with a cathode electrode 1 to extract electron beams, and supporting through holes 22c, 22d penetrated by support pins of the plate spring and the plate spring by etching, then an insulating film made of alumina or the like is formed on both front and back surfaces.
