Abstract
A cover window is provided and includes a substrate and a coating layer. The substrate has a thickness of 60 to 120 μm. The substrate has a Re of 6000 to 12000. The coating layer is coated on the substrate. The cover window has a first direction and a second direction. The first direction is a machine direction of the cover window. The second direction is perpendicular to the first direction. A tensile stress of 50 to 130 MPa is exerted in the first direction. A tensile stress of 140 to 300 MPa is exerted in the second direction. Since the substrate has a Re of 6000 to 12000, a penetrating ray of an incident ray is uniformly distributed on a visible region of the cover window, so as to reduce the phase difference between reflected rays, reduce rainbow patterns, and enhance visibility under a polarizer.
