Abstract: A method of repairing a glass of a display device includes disposing the glass including a first surface, a second surface opposite to the first surface, and a scratch formed on the first surface, the scratch facing toward a gravitational direction, disposing a heating plate on the first surface of the glass, and irradiating a laser on the second surface. A transmittance rate of the laser passing through the glass is greater than an absorption rate of the laser being absorbed in the glass. A portion of the laser irradiated to the second surface reaches the heating plate. The laser reaching the heating plate generates heat. Heat is transmitted to the glass. A portion of the glass adjacent to the scratch is melted by the heat. The portion of the melted glass fills the scratch.

Abstract: A cover window includes a plastic substrate, a first hard coating layer on a first surface of the plastic substrate, the first hard coating layer including a first organic-inorganic composite layer on the first surface, and a first organic layer between the first surface and the first organic-inorganic composite layer, a second hard coating layer on a second surface of the plastic substrate opposite to the first surface, the second hard coating layer including a second organic-inorganic composite layer on the second surface, and a second organic layer between the second surface and the second organic-inorganic composite layer, and a functional layer on the first hard coating layer.
