Organic light emitting diode and manufacturing method thereof

PURPOSE: An organic light emitting device and manufacturing method thereof are provided to adjust the interval between patterned metal electrodes, thereby maximizing light efficiency while light emitted from a light emitting layer passes between patterned metal electrodes. CONSTITUTION: A frontal electrode is coated on a substrate. A hole transfer layer(23) is coated on the frontal electrode and transfers a hole injected from the frontal electrode. A light emitting layer is coated on the hole transfer layer and emits light by combining the hole with an electron. An electron transfer layer(25) is coated on the light emitting layer and transfers an electron to the light emitting layer. A rear electrode(26) is coated on the electron transfer layer and injects an electron into the electron transfer layer. At least one of the frontal electrode and the rear electrode is formed by a patterned metal electrode so that light emitted from the light emitting layer is emitted between the patterned metal electrodes.
