Patent ID: 8188647

Claim:
An electroluminescent device comprising: a substrate; a transistor disposed above the substrate, the transistor including a gate electrode, a silicon film opposing the gate electrode, and a gate insulating film between the gate electrode and the silicon film; a first interlayer insulation film covering the transistor; a second interlayer insulation film disposed above the first interlayer insulation film; a pixel electrode disposed above the second interlayer insulation film and electrically connected to the transistor; an organic EL layer disposed between the pixel electrode and a counter electrode; a capacitor including a first electrode formed by the same material as the silicon film and a second electrode formed by the same material as the gate electrode; and a bank layer, the organic EL layer being formed in a region surrounded by the bank layer, wherein the capacitor is disposed at least in an area where the bank layer is not disposed when viewed in a direction perpendicular to a major surface of the substrate.
