Claim:
1. A method for manufacturing an organic electroluminescent device comprising: forming a first electrode over a first plastic substrate; mixing a first organic compound a second organic compound, and a metal particle into a solvent to prepare a first solution; forming a first electroluminescent layer over the first plastic substrate provided with the first electrode by applying the first solution on the first electrode so that the metal particle is surrounded by a bipolar layer comprising the first organic compound and the second organic compound; forming a second electrode over a second plastic substrate; bonding the second plastic substrate provided with the second electrode to the first plastic substrate provided with the first electrode so that the first electroluminescent layer is interposed between the first electrode and the second electrode to form a bonded substrate, wherein a hole transporting property is higher than an electron transporting property in the first organic compound, wherein an electron transporting property is higher than a hole transporting property in the second organic compound, wherein the metal particle injects a hole and an electron to the bipolar layer by applying an alternative current so that the bipolar layer emits light.
