Abstract
PURPOSE: To improve both convergence and high voltage characteristics, by arranging the ratio of vertical diameter/horizontal diameter of a beam passing hole situated in the center to be larger than those of a beam passing hole situated in the both sides.
CONSTITUTION: In face-to-face arranged plate faces of a focusing electrode G3 and anode G4 that are electrodes constructing the main lens, beam passing holes g31W g33, g41Wg43 of large diameter for passing three electron beams are arranged respectively on horizontal straight lines. Said passing holes are formed into not an independent round hole but a peanut-shaped hole of triple round holes g3, g4 in which their neighboring end parts are piled together and linked. And said passing holes are installed in the focusing electrode G3 and the anode G4 respectively. Flat plate- shaped both end edges 12, 13, 15, 16 of partition electrodes 11, 14 consisting of the turned square U-shaped metal pieces play a role of partition plates in the vicinity of narrowed portions of the triple holes g3, g4, horizontally form the three beam passing holes g31Wg33, g41Wg43, resulting in the provision of a bigger ratio of vertical diameter/horizontal diameter of the central passing hole than that of the both side passing holes.
