Abstract
An electroluminescent display device according to an exemplary embodiment of the present disclosure includes a display panel divided into a display area and a non-display area, a planarization layer and a bank extended to the non-display area of the display panel, an organic layer and a cathode disposed on the bank and extended to the non-display area of the display panel, a trench which is disposed in the non-display area outside the display area and from which the cathode, the organic layer, the bank and the planarization layer are removed; an under-cut structure which is disposed within the trench and composed of the bank and the planarization layer and in which the planarization layer retreats inwards from an end of the bank to generate an under-cut and an adhesive layer and an encapsulation substrate disposed on the cathode. Thus, reliability can be improved and a bezel width can be reduced.
