Abstract
An organic EL panel and a method of forming the same, in which a bottom electrode of an organic EL device is flattened at the surface so that organic layers deposited thereon have uniform thicknesses, thereby avoiding the occurrence of leak currents and allowing favorable luminescence characteristics. The organic EL panel has an organic EL device formed on a substrate, the device comprising the bottom electrode, the organic layers including at least an organic luminescent layer, and a top electrode. The bottom electrode has an etched surface obtained by chemically etching a polished surface of an electrode material film. The organic layers are formed on the etched surface.
