    Abstract: An electroluminescent display apparatus comprises a first subpixel, a second subpixel, and a third subpixel defined on a substrate; a first electrode disposed in each of the first subpixel, the second subpixel, and the third subpixel in the substrate; a bank provided between two adjacent subpixels among the first subpixel, the second subpixel, and the third subpixel to cover an edge of the first electrode; a first light emitting layer disposed on the first electrode of the first subpixel; a second light emitting layer disposed on the first electrode of the second subpixel; a third light emitting layer disposed on the first electrode of the third subpixel; and a second electrode disposed on the first to third light emitting layers, wherein the third light emitting layer is extended onto the bank between the first subpixel and the second subpixel.

    Abstract: Disclosed are an organic light emitting display device and a method of manufacturing the same, which reduce a loss of light emitted from an organic light emitting device, increase a lifetime of the organic light emitting device, and decrease consumption power of the organic light emitting display device. The organic light emitting display device includes a first electrode disposed on a first substrate, a bank disposed on the first electrode for dividing a plurality of emission parts, an organic light emitting layer disposed on the first electrode and the bank, a second electrode disposed on the organic light emitting layer, and an encapsulation layer disposed on the second electrode. The encapsulation layer fills a space between adjacent banks, and a refractive index of the bank is lower than a refractive index of the organic light emitting layer and a refractive index of the encapsulation layer.
