Title:
THIN-FILM TYPE ELECTROLUMINESCENT ELEMENT AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JP3750199
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a thin film EL element and establish a manufacturing method for it, with which drop of the brightness is lesser even through a long period of light emission.
SOLUTION: The first electrode layer, the first insulative layer, a light emitting layer consisting of a material prepared at least by adding rare earth element(s) to alkali earth sulfide, the second insulative layer, and the second electrode layer are laminated on a base board of glass in the sequence as named, and thus a thin film EL element is formed, from which impurities such as carbon dioxide, oxygen, or water/moisture contained in or at the surface of the light emitting layer have been removed. Removal is made by subjecting the light emitting layer to a sputtering or vacuum heat treatment.
