METHOD FOR MANUFACTURING ELECTRON-EMITTING DEVICE AND METHOD FOR MANUFACTURING DISPLAY

摘要

A method for manufacturing an electron-emitting device wherein a large number of carbon nanotubes can be perpendicularly oriented in the surface of an emitter layer is disclosed. The method comprises a step wherein a cathode electrode is formed on a supporting substrate (4), a step wherein an emitter layer (10) containing carbon nanotubes (11) and a binder material is formed on the cathode electrode, a step wherein the carbon nanotubes (11) are exposed in the surface of the emitter layer (10) by removing the binder material from the upper portion of the emitter layer (10), and a step wherein the carbon nanotubes (11) exposed in the surface of the emitter layer (10) are oriented generally perpendicular to the supporting substrate (4).
