Abstract
To provide an image display device including a lower electrode, an upper electrode, and an electron acceleration layer composed of an insulator or a semiconductor provided there between, and further including a thin film electron source array that emits electrons from the upper electrode, and a phosphor surface, wherein degradation of an electron emission characteristic caused by an increase of a work function due to an adhesive material to the above-described upper electrode is suppressed. An amount of S content adhering to the upper electrode is set equal to or less than 20 mol % of a total amount of elements used as the upper electrode in terms of elements by using an element belonging to Group VIII or Group Ib or a laminated film or alloy film thereof as a component of the upper electrode of the thin film electron source.
