Manufacturing method of organic electroluminescent device and an organic electroluminescent device

摘要

The present invention provides a manufacturing method of organic electroluminescent device and the organic electroluminescent device that unevenness in the surface of the transparent electrode layer is covered by the organic luminescence media layer without being affected by the unevenness. In a manufacturing method of the organic electroluminescent device which emits light by applying voltage to organic luminous layer 5 between transparent electrode layer 3 and a counter electrode layer 6 , organic luminous layer 8 is formed by using ink containing low molecular organic luminescent material of which molecular weight is less than or equal to 5000.
