    Abstract: Discussed is an electroluminescence display apparatus for preventing the performance, efficiency, and lifetime of a device from being reduced. The electroluminescence display apparatus includes a substrate including an active area including a plurality of pixels, a circuit element layer disposed on the substrate, a first electrode disposed on the circuit element layer, an auxiliary electrode disposed on the circuit element layer and spaced apart from the first electrode, a first light emitting layer disposed on the first electrode, a buffer layer disposed on the first light emitting layer, a second light emitting layer disposed on the buffer layer and the auxiliary electrode, and a second electrode disposed on the second light emitting layer. In the electroluminescence display apparatus, since the buffer layer is formed on the first light emitting layer through an inkjet process, the buffer layer can be provided on only the first light emitting layer, and thus, the buffer layer can be formed of an organic material, thereby enhancing the device performance of a blue pixel.
