HIGH CONTRAST ORGANIC LIGHT EMITTING DEVICE AND A DISPLAY APPARATUS COMPRISING THE SAME CAPABLE OF PREVENTING EXTERNAL LIGHT REFLECTION

摘要

PURPOSE: A high contrast organic light emitting device and a display apparatus comprising the same are provided to increase light intensity by using a micro cavity structure.;CONSTITUTION: A first electrode(502) is formed in the upper part of a substrate. An organic layer(503) is formed in the upper part of the first electrode. A second electrode(504) is formed in the upper part of the organic layer. The first electrode includes a transparent or semi-transparent electrode layer. The second electrode includes a reflection electrode layer.;COPYRIGHT KIPO 2013
