Abstract:
1. An EL display device comprising: first and second pixel electrodes formed above a substrate, for each sub-pixel within a unit pixel; a counter electrode opposite to the first and second pixel electrodes; a light-emitting layer provided between the first and second pixel electrodes and the counter electrode; a sealing member which seals the light-emitting functional layer; an organic bank surround the light-emitting layer; and a lyophilic control layer disposed between the first pixel electrode and the second pixel electrode, and having a higher lyophobic property than the organic bank, wherein the first and second pixel electrodes and the counter electrode are formed of a transparent conductive film, a sealing-side light-emitting area for extracting light emitted from the light-emitting layer from the sealing member is composed of the first pixel electrode, a substrate-side light-emitting area for extracting light emitted from the light-emitting functional layer from the substrate is composed of the second pixel electrode, and the light-emitting layer emits light independently in the sealing-side light-emitting area and the substrate-side light-emitting area.
