Original Abstract Submitted
An electroluminescent display device according to an exemplary aspect of the present disclosure includes a substrate including an active area and a non-active area outside the active area, a planarization layer over the substrate and extending from the active area to the non-active area, a bank on a planarization layer extending to the non-active area, an organic layer on the bank, a cathode on the organic layer, a capping layer over the cathode, a trench pattern configured in the non-active area, from which the capping layer, the cathode, and the organic layer are removed and a step alleviation layer filling the trench pattern and planarizing an upper portion of the trench pattern, the capping layer adjacent to the trench pattern may be recessed inwardly compared to the cathode, so that a bezel width is reduced, and the same time, reliability of moisture permeation prevention performance may be improved.
