摘要:
An organic EL element having a functional layer with a uniform film thickness is provided. The organic EL element of the present invention contains a substrate; an anode electrode set on the substrate; an organic EL layer set on the anode electrode; a cathode electrode set on the organic EL layer; and a bank having a forward tapered shape, which define the organic EL layer. The bank contains a fluorine resin, the fluorine concentration at a top of the bank is higher than the fluorine concentration at a bottom surface of the bank, and a height of the top of the bank from the substrate is 0.8 to 1.2 μm.
