Abstract: A cover window includes a plastic layer and a first hard coating layer disposed on an upper surface of the plastic layer. An edge of the cover window includes a vertical side part perpendicular to the upper surface of the plastic layer. A first inclination part is connected to the vertical side part and is inclined with respect to the vertical side part. The vertical side part and the first inclination part include a mechanical processing trace. An edge of the first hard coating layer adjacent to the first inclination part includes a laser processing trace.
