Abstract:
An organic EL element includes a planarized layer arranged on a substrate, an insulation layer which is arranged on the planarized layer with the region corresponding to a subpixel of the planarized layer left exposed at least partly, a pixel electrode which has an opening that defines the region corresponding to the subpixel and which is arranged on a bank arranged on the insulation layer and on the exposed part of the planarized layer, a transparent conductive layer arranged on the pixel electrode, an emission layer arranged in the opening and above at least the transparent conductive layer, and a counter electrode arranged above the emission layer. The insulation layer is interposed between a bottom of the bank and the planarized layer. An upper surface of the planarized layer is coated with at least one of the pixel electrode and the insulation layer.
