Patent ID: 7696686

Claim:
An image display device comprising: a plurality of thin film electron sources arranged in two dimensions; and a phosphor surface comprising a plurality of colors of phosphors arranged corresponding to each of the thin film electron sources, wherein the image display device displays an image by exciting the phosphor to emit light with electrons emitted from the thin film electron source, wherein the thin film electron source array comprises a lower electrode, an upper electrode, and an electron acceleration layer sandwiched between the upper electrode and the lower electrode, and further comprises a plurality of thin film electron sources that emit electrons from the upper electrode, wherein a formation material of the upper electrode comprises an element belonging to Group VIII or Group Ib of the periodic table or a laminated film or alloy film thereof, and wherein in the upper electrode, an amount of S content adhering to a surface thereof is equal to or less than 20 mol % of a total amount of elements of the formation material of the upper electrode in terms of elements.
