ELECTRON-EMITTING ELEMENT, AND MANUFACTURING METHOD FOR IMAGE DISPLAY APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for an electron-emitting element which has high electron-emitting efficiency and is highly reliable.

SOLUTION: The manufacturing method for an electron-emitting element includes: a first process of preparing a first conductive film on at least a side face of an insulating layer having an upper face and the side face connected with the upper face; a second process of preparing a second conductive film from above the upper face over to above the side face of the first conductive film on the first conductive film; and a third process of etching the second conductive film.
