Abstract: The present disclosure relates to curved cover glass used for a curved display, and a manufacturing method thereof. The present disclosure provides tempered glass comprising: glass including a curved area; and a low-reflection coating layer, coated on a surface of the glass, composed of a mixture of a binder and a hollow material, wherein the glass comprises potassium ions which penetrate up to a predetermined depth therein. According to the present disclosure, a low-reflection coating layer is formed prior to curved surface processing, and thus, the low-reflection coating layer can be uniformly formed even on areas having different curvatures. Thus, the present disclosure can minimize the color difference generated in curved glass due to low-reflection coating layers.
