Abstract
An electroluminescent display device includes a substrate including an active area and a non-active area which encloses the active area, a planarization layer which is disposed on the substrate and extends from the active area to the non-active area, a bank over the planarization layer, an organic layer over the bank, a cathode over the organic layer, a trench pattern which is disposed in the non-active area and the cathode and the organic layer are removed and a step relieving layer which fills the trench pattern and is disposed to planarize an upper portion of the trench pattern to delay a moisture permeation speed from the side surface, thereby improving the reliability and reducing the bezel width at the same time.
