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.
