ORGANIC LIGHT EMITTING DIODE FOR PREVENTING VOLTAGE DROP BY AN UPPER LAYER AND INCREASING LIGHT EMITTING EFFICIENCY BY REDUCTION OF A DRIVING VOLTAGE

摘要

PURPOSE: An organic light emitting diode is provided to form a common electrode in a double layer of an upper layer and a lower layer and to form the lower layer by ytterbium.;CONSTITUTION: A pixel electrode(191) is formed on a substrate. An organic light emitting member(370) is formed on the pixel electrode. A common electrode(270) is formed on the organic light emitting member. The common electrode includes an upper layer and a lower layer. The lower layer includes ytterbium, compound of fluorinated lithium, or compound of ytterbium and silver. The upper layer includes the silver.;COPYRIGHT KIPO 2013
