Patent ID: 7986080

Claim:
An electron-emitting device, comprising: a substrate, having a first side and a second side which is opposite to the first side; a first electrode pattern layer, disposed on the first side of the substrate; a conductive pattern layer, disposed on the substrate and the first electrode pattern layer, the conductive pattern layer partially covering the first electrode pattern layer, wherein the conductive pattern layer has an electron-emitting region; and a second electrode pattern layer, disposed on the second side of the substrate, the second electrode pattern layer partially covering the conductive pattern layer, wherein, the first electrode pattern layer, the conductive pattern layer and the second electrode pattern layer are stacked in this order on the substrate, there is a segmented step on an edge of the conductive pattern layer covering the first electrode pattern layer, and the electron-emitting region is disposed at the segmented step in the conductive pattern layer, and a plurality of electrons are transported in the first electrode pattern layer and the second electrode pattern layer, and the electrons are transported into the conductive pattern layer for being emitted out from the electron-emitting region.
