電流にばらつきを生じて発光画像に輝度むらを生じる。In a high-definition tube for displaying television images in which the number of anodes or the number of anodes arranged is two or more, not only the viewing angle θ0 becomes extremely small, but also electrode formation becomes extremely difficult. Further, when the electrode width is set to a minimum, the resistance value increases, causing variations in the glow discharge current and causing uneven brightness in the luminescent image.

Face plate 2ff: Can be viewed through a wide-angle field of view. Furthermore, there is an advantage that not only can the resistance value be lowered by increasing the cross-sectional area of each anode and each cathode, but also that the cathode current can be suppressed by the insulating layers ga, gb, . Note that when the thickness of the cathode is large, the width of the insulating layer can be approximated to the width of the cathode.
