Claims
- 1. An electron source comprising:
- (a) a substrate;
- (b) plurality of electron emitters arranged on said substrate, said electron emitters comprising first and second electrodes;
- (c) plural first wirings arranged on said substrate substantially aligned in one direction and connected to said first electrodes; and
- (d) plural second wirings aligned substantially perpendicular to the first wirings and connected to said second electrodes, said second wirings overlying said first wirings and defining intersections between said first and second wirings with an electrically insulating layer disposed between said first and second wirings at said intersections;
- wherein said first wirings cover a portion of said first electrodes, said second wirings cover a portion of said second electrodes, and said first electrodes are longer than said second electrodes in the longitudinal direction of said second wirings, and
- wherein said first and second electrodes oppose each other, and a direction in which said first and second electrodes are oppposed to each other is substantially parallel to the alignment direction of said second wirings.
- 2. An electron source according to claim 1, wherein said electrically insulating layer comprises a plurality of insulating layers having a longitudinal direction which is substantially parallel to the longitudinal direction of said second wirings.
- 3. An electron source according to claim 2, wherein said insulating layers provide a recessed portions where said second wiring is connected to said second electrodes.
- 4. An electron source according to claim 1, wherein electron emitter further comprises a conductive film having an electron emission portion, and said conductive film covers said first and second electrodes.
- 5. An electron source according to claim 1, wherein said emission element further comprises a conductive film having an electron emitting section; and said conductive film covers said first and second electrodes.
- 6. An image forming apparatus comprising:
- (a) an electron source according to any one of claims 1 to 5, and an
- (b) image forming member.
- 7. An image forming apparatus according to claim 6, wherein said image forming member comprises a fluorescent film.
