Abstract
Provided is a technique which easily forms a bank the inner lateral surface of which has a part (lower part of the inner lateral surface) made to be lyophilic. The technique provides an organic EL display panel containing a plurality of organic EL elements in which each organic EL element comprises a substrate, an anode disposed on the substrate, an organic light emitting layer disposed on the anode, a cathode disposed on the organic light emitting layer, and a forward-tapered bank which regulates the area of the organic light emitting layer. A lyophobic organic film is disposed on the upper surface of the bank and the surface of the upper part of the tapered portion of the bank but not disposed on the surface of the lower part of the tapered portion of the bank of the organic EL element.
