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.
