ELECTRON EMISSION ELEMENT, DISPLAY EMPLOYING ELECTRON EMISSION ELEMENT, AND METHOD FOR FABRICATING ELECTRON EMISSION ELEMENT

WIPO Patent Application WO/2007/114103

A1

An electron emission element in which electron emission efficiency is enhanced while protecting the element against damage. The electron emission element comprises an amorphous electron supply layer (4), an insulator layer (5) formed on the electron supply layer (4), and an upper electrode (6) formed on the insulator layer (5), and emits electrons when an electric field is applied between the electron supply layer (4) and the upper electrode (6). The electron emission element has a recess (7), which is formed by cutting the upper electrode (6) and the insulator layer (5) to expose the electron supply layer (4), and a carbon layer (8) covering the upper electrode (6) and the recess (7) excepting the inside portion (4b) of the exposed surface (4a) of the electron supply layer (4) while being in contact with the edge portion (4c) thereof.
