Organic electro-luminescence device

Abstract

An organic electro-luminescence device includes a substrate, a hole injection layer disposed on the substrate, an organic layer disposed on the hole injection layer, a buffer layer disposed on the organic layer, and an electron injection layer forming above the buffer layer. The buffer layer is needed for protecting the organic layer while the electron injection layer is being formed. Within, the organic layer includes a light-emitting layer and an electron transporting layer disposed on the light-emitting layer. The electron transporting layer includes Cesium fluoride.
