ORGANIC ELECTROLUMINESCENT ELEMENT AND METHOD FOR MANUFACTURING THE SAME

摘要

There are provided an organic electroluminescent element which is highly precise and minute, uniform in light emission, free from cross talk, resistant to external pressure, and further excellent in sealing properties and a process for producing the above element. The organic electroluminescent element 1 which is equipped, between a lower electrode 3 and a counter eletrode 4 each on a substrate 2, with an intervening organic layer 5 comprising a light-emitting layer, comprises an inter -insulator film 6 having a coefficient of water absorption of at most 0.1% in a non-light-emitting element portion; step portions 9 in the inter-insulator layer 6 which define the boundary between a light-emitting element portion and a non-light-emitting element portion and which comprise rising parts almost perpendicular to the surface of the lower electrode 3; and a sealing plate or a sealing lid 7 which is placed over the inter-insulator layer 6 and which is attached to the substrate 2 via an adhesive layer 8.
