Abstract
An image display device includes comb-shaped horizontal deflection electrodes disposed interleavingly in a first plane with a space therebetween for forming electron beam passages and comb-shaped vertical deflection electrodes disposed interleavingly in a second plane adjacent and parallel to the first plane. The capacitance between the horizontal deflection electrode confronting the vertical deflection electrodes and the capacitance between the horizontal deflection electrode confronting the vertical deflection electrode are made equal to each other. Also, the capacitance of the vertical deflection electrode confronting the horizontal deflection electrodes and the capacitance of the vertical deflection electrode confronting the horizontal deflection electrodes are made equal to each other, whereby the voltage effect induced by the other deflection electrode can be canceled and a good quality image can be obtained.
