Abstract
Control plates in flat display devices are located between the cathode and the screen and serve to control the electron flow. To permit easy contacting even if the conductors (1) of the control plates are very narrow, the conductors (1) alternately have broadened ends on opposite sides of the control plate. The ends are broader by the width of the respective adjacent conductor.
