Patent ID: 8130177

Claim:
An organic EL display panel comprising a plurality of organic EL devices each including: a substrate; an anode formed over the substrate; an organic emitting layer formed over the anode, the organic emitting layer having a uniformly-thick area; a cathode formed over the organic emitting layer; a forward tapered bank defining a region for the organic emitting layer, the bank having a top surface and an inclined side surface, the bank being in contact with the anode and made entirely of organic insulating material; and a lyophobic organic film formed on the top surface of the bank and a upper portion of the inclined side surface of the bank, wherein a lower portion of the inclined side surface of the bank includes no lyophobic organic film, and the organic emitting layer is formed by a coating method, a contact point between a surface of the organic emitting layer, which surface faces the cathode, and the inclined side surface of the bank is at a boundary between a region with the lyophobic organic film and a region without the lyophobic organic film, and the contact point structured and arranged above the uniformly-thick area of the organic emitting layer.
