Abstract:
1. An image display apparatus, comprising an electron source having a plurality of electron-emitting devices comprising a pair of device electrodes disposed in opposition to each other with a gap in between and an electron-emitting region positioned between the pair of device eletrodes; an electrode positioned in opposition to said electron source; and a spacer being positioned between said electron source and said electrode, and positioned adjacent to at least some electron-emitting devices among said plurality of electron-emitting devices, wherein said electron source has plural row wirings and plural column wirings, and each of said plural electron-emitting devices has one of said pair of device electrodes connected to one of said plural row wirings and a further one of said pair of device electrodes connected to one of plural column wirings, and said spacer is positioned on at least one of said row wirings, wherein the longitudinal direction of the gap between the pair of device electrodes of at least one electron-emitting device adjacent to said spacer has an inclination to the longitudinal direction of at least one column wiring, and wherein the inclination of the at least one electron-emitting device is made larger as a distance between the spacer and the at least one electron-emitting device adjacent to the spacer is made smaller.
