<p>PROBLEM TO BE SOLVED: To keep accurate gaps between a gate electrode and electron emitting layers. SOLUTION: This cold cathode is equipped with an insulating substrate 2, cathodes 3 formed on the insulating substrate 2, electron emitting layers 4 formed on the respective cathodes 3, and a gate electrode 6 having a plurality of opening parts above the electron emitting layers 4 with insulating organic long fibers 5 interposed between the gate electrode 6 and side parts and/or upper surface parts of the electron emitting layers 4.</p> |
