Abstract
PURPOSE:To produce high density and uniform picture image by arranging and fixing a plurality of metal thin wires in a ccorrespondence to the through-hole in a grid electrode board to constitute an electron beam control electrode thereby enabling the high density arrangement of said control electrodes with high accuracy. CONSTITUTION:Grid electros 9, 13 formed with rectangular through-holes 10, 14 are arranged while facing each other with predetermined interval through ribs 11, 15. The electron beam control electrode pair (12a1, 12a2)-(12c1, 12c2) composed of metal thin wire are fixed to the grid electrode with correspondence to the through=holes 10, 14. Since the high density and high accurate arrangement of the metal wire is facilitated, each beam control electrode pair can be arranged accurately. Consequently the high density and uniform picture image can be produced.
