    Abstract: A display device includes: a display panel layer including a display area and a second non-light emitting area, the display area including a plurality of light emitting areas and a first non-light emitting area, the first non-light emitting area being around each of the light emitting areas, and the second non-light emitting area being outside the display area; a window coating layer directly on a first surface of the display panel layer; and a first curl-preventing pattern overlapping at least one of the first non-light emitting area and the second non-light emitting area when viewed in a plan view and contacting the window coating layer. The first curl-preventing pattern is configured to prevent the window coating layer from curling.
