Abstract
An organic EL cell for preventing moisture that deteriorates the light-emitting characteristics of the organic EL cell including a substrate, a laminate structure formed on the substrate, wherein the laminate structure includes at least an anode, an organic light emitting layer, and a cathode, a first sealing film formed on the laminate structure, and a second sealing film formed on the first sealing film.
Claims22
An organic EL cell for preventing moisture that deteriorates the light-emitting characteristics of the organic EL cell, comprising:
- a substrate;
- a laminate structure formed on the substrate, wherein the laminate structure includes at least an anode, an organic light emitting layer, and a cathode;
- a first sealing film formed on the laminate structure;
- and
- a second sealing film formed on the first sealing film.
A method for producing an organic EL cell for preventing moisture that deteriorates the light-emitting characteristics of the organic EL cell and that includes a substrate and a laminate structure formed on the substrate, wherein the laminate structure includes at least an anode, an organic light emitting layer, and a cathode, comprising the steps of forming a first sealing film on the laminate structure and forming a second sealing film on the first sealing film.
The method of 16, wherein the inorganic passivation film is that of silicon nitride formed by a plasma CVD.
The method of 13, wherein the inorganic passivation film is that of silicon nitride formed by a plasma CVD.
