Patent ID: 6903504

Claim:
An electron source plate comprising: a substrate; electron-emitting devices each provided with a pair of device electrodes and an electron-emitting portion disposed between the pair of device electrodes; column wirings each electrically connected to one of the pair of the device electrodes of at least one of the electron-emitting devices; and row wirings each electrically connected to another one of the pair of device electrodes of the at least one of the electron-emitting devices, and crossing the column wirings through an insulating layer, wherein a crossing point between the row and column wirings is disposed over part of the one of the pair of device electrodes, and the one of the pair of device electrodes and the column wiring electrically connected thereto are stacked, substantially perpendicularly to the substrate, through an isolation layer comprising a material different from either of the one of the pair of device electrodes and that column wiring, for isolating the one of the pair of device electrode from that column wiring.
