Abstract
An organic electroluminescence device is disclosed. The organic electroluminescence device includes a light emitting layer disposed on a substrate and an encapsulation layer covering the light emitting layer. The encapsulation layer includes at least one inorganic layer and at least one organic layer, wherein the inorganic layer and the organic layer of the encapsulation layer are disposed alternately, and the at least one inorganic layer is disposed on the light emitting layer and covers the light emitting layer; and two buffer layers, wherein each of the buffer layers is disposed between the inorganic layer and the organic layer which are adjacent, and a material of the buffer layer is at least one of a tetramethylsilane monomer, an ethoxysilane monomer, or a silicon oxycarbide monomer.
