摘要

PROBLEM TO BE SOLVED: To make uniform the characteristic of a surface conduction type electron emission element. SOLUTION: When a material forming a conductive thin film 4 on which an electron emitting portion 5 is formed or a liquid containing its raw material is applied on a substrate 1 and is heated and baked to form an electron emission element which forms the conductive thin film, the liquid which can be hardened by application of predetermined energy is used, and energy is applied to the liquid by an energy application means 41 at the same time as or after application of the liquid, to harden a part of the liquid.
