Electron emission device, electron emission display device using the same, and method for manufacturing the same

An electron emission display device, comprising:

• a first substrate and a second substrate facing each other;
• cathode electrodes on the first substrate, each cathode electrode having a main electrode and a subsidiary electrode;
• resistance layers on the subsidiary electrodes, the resistance layers varying in resistivity along a thickness direction of the resistance layers;
• electron emission regions connected to the resistance layers;
• gate electrodes separated from the cathode electrodes and having an insulating layer interposed therebetween;
• phosphor layers on a surface of the second substrate facing the first substrate;
• and
• at least one anode electrode adjacent to the phosphor layers.

A method of manufacturing an electron emission device, comprising:

• forming cathode electrodes on a substrate;
• forming diffusion target layers at predetermined locations on the cathode electrodes;
• and
• converting the diffusion target layers into resistance layers by diffusing a conductive diffusive material contained in the cathode electrodes into the diffusion target layers.
