    Abstract: An electroluminescent display device can include a substrate including an active area and a non-active area having a gate in panel (GIP) area, a thin film transistor disposed on the substrate, a GIP circuit unit disposed on the substrate in the GIP area, a sacrificial layer disposed on the GIP circuit unit, a planarization layer disposed over the thin film transistor and the sacrificial layer, an anode disposed on the planarization layer, a bank disposed on the planarization layer and exposing a portion of the anode, a light emitting unit and a cathode disposed on the anode and the bank, a trench pattern disposed on the sacrificial layer, and a buffer layer disposed on the cathode and an inner surface of the trench pattern. As a result, reliability of the display panel can be improved by preventing diffusion of residual foreign materials and moisture permeation.

    Abstract: Disclosed are an electroluminescent display device and a method of manufacturing the same. The electroluminescent display device includes a first bank on a substrate, an anode electrode extending to one side and another side of the first bank in an area exposed by the first bank, a second bank on each of one side and another side of the anode electrode, a light emitting layer on an upper surface of the anode electrode exposed by the second bank, and a cathode electrode on the light emitting layer. Since the anode electrode is provided on the first bank, the anode electrode is prevented from being damaged in a process of patterning the first bank.
