Abstract: An electroluminescent display device includes a display panel having a display area and a non-display area. A planarization layer is over the non-display area. A bank is on the planarization layer. An organic layer and a cathode are on the bank. A trench pattern extends through the cathode and the organic layer. An adhesive layer and an encapsulation substrate are disposed over the cathode. The adhesive layer covers the trench pattern. The adhesive layer is effective to slow a rate of moisture penetration to a side surface of the non-display area, allowing for improvements in reliability and a reduction in bezel width.

Abstract: A display device may prevent signal lines in a non-display area from being damaged by particles. The display device may include a first substrate including a display area and a non-display area, a first electrode in the display area over the first substrate, a light emitting layer over the first electrode, a second electrode over the light emitting layer, lines in the non-display area over the first substrate, organic patterns over the lines and spaced apart from one another, an adhesive layer over the organic patterns, and a second substrate over the adhesive layer. The light emitting layer and the second electrode are provided from the display area to the non-display area, and spaced distances among the organic patterns are shorter than a distance from an upper surface of the second electrode provided over the organic patterns to an upper surface of the adhesive layer.
