Abstract: PROBLEM TO BE SOLVED: To enhance electron emitting efficiency within a range showing no ill effect on variation with lapse of time by driving. SOLUTION: In this electron emitting element, the amount of one kind or more of element selected from a group of a lithium, potassium, sodium, calcium, strontium and barium included in a deposit 10 mainly containing a carbon is controlled by using a method of introducing a row gas further containing the element in the atmosphere including an organic substance when activated and controlling the amount of the row gas or method of coating the solution containing the element in a form of an organometallic compound, etc., after forming the deposit and then thermally treating it to contain the element. Thereby, the ratio of the element to carbon is 1 mol% to 5 mol%, inclusive.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of suppressing degradation and unevenness of brightness by stabilizing electron emitting quantity from an electron emitting element and suppressing degradation of element characteristics. SOLUTION: This image forming device includes an envelop 5 formed by oppositely arranging an electron source substrate 1 provided with a matrix-wired plurality of electron emitting elements and a face plate 4 having a fluorescent film 7. Wiring of the electron source substrate 1 is formed by non-evaporation type getter material. Therefore, the getter material is arranged in a large area and in a periphery of a part emitting gas most without special processes for getter formation.
