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.
