Abstract
A white light emitting organic electro-luminescent (EL) device and a method for fabricating the same are provided. The device comprises: a substrate; a bottom electrode formed on a top surface of the substrate; at least an organic layer comprising an organic emitting layer formed on a surface of the bottom electrode to emit a first-color light; at least a transparent opposed electrode formed on a surface of the organic layer; and a sealing cap layer covering the organic layer and the transparent opposed electrode, wherein a color conversion layer is disposed on an inner surface of the sealing cap layer for converting a percentage of the first-color light into a second-color light and a third-color light. Therefore, a white light source is achieved by mixing the three primary colors.
