ABSTRACT:
The present invention provides an organic electroluminescent panel, a production method thereof, and an organic electroluminescent display device, in which color mixing between adjacent pixels, caused by overflow or pull-in of a liquid material is suppressed and discontinuity (physical and electrical separation by the step) of an upper electrode is reduced when an organic film such as a luminescent layer is formed by an application method such as an ink jet printing method. The organic electroluminescent panel of the present invention is an organic electroluminescent panel comprising a lower electrode, a bank, an organic film, and an upper electrode on a substrate, wherein the organic electroluminescent panel has: two or more bank regions having different film thicknesses; and an organic film region surrounded by the two or more bank regions, the organic film region having a planar shape of a quadrangle or a substantial quadrangle with a rounded vertex or side.
