FUNCTIONAL THIN FILM ELEMENT, MANUFACTURING METHOD OF FUNCTIONAL THIN FILM ELEMENT AND ARTICLE USING FUNCTIONAL THIN FILM ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a functional thin film element extended in a service life by reducing its driving voltage by arbitrarily controlling the height of a potential barrier on a bonded interface between an anode electrode and a functional thin film; to provide an article using the functional thin film element; and to provide a manufacturing method of a functional thin film element capable of being driven at a low voltage by simplifying the manufacturing method to reduce a cost. SOLUTION: This functional thin film element is provided with a substrate 2, the anode 3 formed on the substrate 2, a luminescent layer 4 formed on the anode 3 and a cathode 5 formed on the luminescent layer 4; and is characterized by that negative ions 6 are doped into a surface of the anode 3 on the bonded interface between the anode 3 and the luminescent layer 4 or a surface of the luminescent layer 4.
