ABSTRACT:
In an image display apparatus including a multi-electron beam source having a plurality of electron-emitting devices (51) wired in a matrix using a plurality of column wiring layers and a plurality of row wiring layers, and a plurality of phosphors which are excited to emit light upon irradiation of electron beams, a delta arrangement of phosphors is realized with the simple arrangement of the multi-electron beam source. The column and row wiring layers are straight layers, the plurality of phosphors (R, G, and B) are arranged in a delta arrangement, and the multi-electron beam source is adjusted such that a plurality of electron beams emitted therefrom reach the phosphors. For this reason, the directions of electrons emitted from the devices on an odd ((2p-1)th) row and an even (2pth) row along orbits are reversed.
