Abstract
Disclosed is an organic EL device which comprises an organic light-emitting layer having a uniform thickness even though the organic light-emitting layer is formed by a coating method. Specifically disclosed is an organic EL device comprising a substrate, an anode arranged on the substrate, an organic light-emitting layer arranged on the anode, and a bank defining an arrangement region for the organic light-emitting layer. A groove is formed on the upper surface of the bank, and the outer or inner edge of the groove defines the border of the organic light-emitting layer.
