Patent ID: 7956533

Claim:
A bottom emission type electroluminescent display device comprising a display panel including a plurality of scan lines, a plurality of data lines, and a plurality of pixel circuits on a substrate, wherein each pixel circuit comprises: an electroluminescent element including a transparent electrode layer between the substrate and a reflective electrode layer comprising a metallic layer, and an emitting layer between the transparent electrode layer and the reflective electrode layer; and a driving circuit coupled to the electroluminescent element, wherein the transparent electrode layer of the electroluminescent element at least partially overlaps a power source line for supplying power to the driving circuit, with a first insulation film therebetween, wherein the reflective electrode layer is configured to reflect light from the emitting layer toward the substrate and through the transparent electrode for bottom emission, and wherein the transparent electrode layer of the electroluminescent element at least partially overlaps one of the plurality of scan lines with the first insulation film therebetween.
