Abstract:
1. An image display apparatus comprising: a rear plate including an electron-emitting device; a face plate including a resistive anode and a feed electrode, the feed electrode being disposed outside of the resistive anode so as to surround the resistive anode and connect the resistive anode and a power supply, the face plate facing the rear plate such that the resistive anode faces the electron-emitting device, a resistance of the resistive anode being greater than a resistance of the feed electrode; and a plate-like spacer disposed between the rear plate and the face plate, the plate-like spacer having a longitudinal-direction end disposed outside of the resistive anode so as to lie across the resistive anode, wherein the face plate further includes a low-potential electrode set at a lower potential than that of the resistive anode, the low-potential electrode being disposed between the resistive anode and the feed electrode, and the longitudinal-direction end of the plate-like spacer being disposed between the resistive anode and the feed electrode so as to overlap the low-potential electrode.
