Abstract
A plurality of pixel areas are defined on the surface of a substrate. A partition wall is disposed on the surface of the substrate in an area between adjacent pixel areas. The partition wall comprises a lower portion made of inorganic insulating material and an upper portion made of insulating material having etching characteristics different from the etching characteristics of the lower portion and disposed on the lower portion. The upper portion protrudes from the side walls of the lower portion toward the pixel areas. Lower electrodes are formed on the pixel areas. Organic layers are disposed on the lower electrodes and contains organic luminescence material which emits light upon current injection. Upper electrodes are disposed on the organic layers.
