Electron emission device and electron emission display device using the same

摘要

An electron emission device is disclosed. The electron emission device includes a resistance layer for electrically connecting a line electrode and isolate electrodes included in the cathode electrode. The cathode electrode can maintain a uniform voltage due to the resistance layer. A protection layer is located on the resistance layer. The protection layer prevents conductive elements contained in the resistance layer from diffusing over the protection layer. The protection layer also prevents the resistance layer from being oxidized.
