A method of repairing glass for a display device is provided. The method comprises the following steps: arranging glass comprising a first surface, a second surface opposite to the first surface and a scratch formed on the first surface, wherein the scratch of the glass faces a gravity direction; arranging a heating plate on the first surface of the glass; and irradiating laser on the second surface of the glass. The transmittance of the laser light through the glass is greater than the absorptivity of the laser light absorbed in the glass. A part of the laser light irradiated to the second surface reaches the heating plate. The laser reaching the heating plate generates heat. Heat is transferred to the glass. A portion of the glass adjacent the scratch is melted by heat. Melted glass fills the scratch. 本发明提供了修复用于显示装置的玻璃的方法。该方法包括：设置包括第一表面、与第一表面相对的第二表面和形成在第一表面上的划痕的玻璃，玻璃的划痕面向重力方向；将加热板设置在玻璃的第一表面上；以及在玻璃的第二表面上照射激光。激光穿过玻璃的透射率大于激光在玻璃中被吸收的吸收率。照射到第二表面的激光中的一部分到达加热板。到达加热板的激光产生热量。热量被传递到玻璃。玻璃的与划痕相邻的部分通过热量被熔化。熔化的玻璃填充划痕。
