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.
