ELECTRIC FIELD ELECTRON EMITTING ELEMENT, CARBON PARTICLE FOR ELECTRIC FIELD ELECTRON EMITTING ELEMENT EMITTER PART, AND PICTURE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electric field electron emitting element which is available at a low price, and superior in an electric field electron discharge characteristic.

SOLUTION: This is the electric field discharge element having an emitter part and an anode part, graphite particles are contained in the emitter part, and the graphite particles are collected or bonded so that a plurality of oriented faces of the flat particles become non-parallel.
