Title: Fabricating method for thin film electroluminescence element
Inventor: DEGUCHI KOJI
IPC: H05B33/12
Filed: 1988-06-06
Abstract: PURPOSE:To provide a film type electroluminescence(EL) element of high quality and good mass producibility by decreasing its amount of sulfur evaporation with passage of the time, when the sulfur is evaporated together with sulfides of alkali earth elements. CONSTITUTION:When a clear electrode 2 is formed on a glass base plate 1 followed by forming of a light emitting layer 3 by means of electron beam evaporation method, sulfur is evaporated together with sulfides of alkali earth elements, wherein the amount of sulfur evaporation is decreased with passage of the time. Then an insulative layer 4 of a back electrode 5 are formed on the light emitting layer 3. This lessens the total amount of sulfur evaporation to reduce wear of the device due to sulfur to allow obtainment of a film type EL element of high quality and with good mass producibility.
