Abstract
An image display apparatus includes a rear plate including an electron-emitting device; and a luminescent screen including a plurality of light-emitting members, a plurality of anode electrodes positioned so as to overlap the light-emitting members, a partition wall member positioned between the light-emitting members adjacent to each other, a stripe-shaped resistance member electrically connecting the anode electrodes adjacent to each other and being positioned on the partition wall member, and a feeding electrode electrically connecting the resistance member to a power supply, wherein the feeding electrode is, on a mesh-shaped base adjacent to the partition wall member, in contact with the resistance member and a terminal of the power supply circuit.

An image display apparatus comprising:
- a rear plate including an electron-emitting device;
- and
- a luminescent screen including a substrate and, on the substrate, a plurality of light-emitting members, a plurality of anode electrodes positioned so as to overlap the light-emitting members, a partition wall member positioned between the light-emitting members adjacent to each other and projecting from a surface of the substrate, a resistance member electrically connecting the anode electrodes adjacent to each other and being positioned on the partition wall member, and a feeding electrode electrically connecting the resistance member to a power supply circuit,
- wherein the feeding electrode is, on a mesh-shaped base adjacent to the partition wall member, in contact with the resistance member and a terminal of the power supply circuit.
