Title: CURVED GLASS AND MANUFACTURING METHOD THEREOF
Abstract:
The present invention relates to curved cover glass used for a curved display, and a manufacturing method thereof. The present invention 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 invention, 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 invention can minimize the color difference generated in curved glass due to low reflection coating layers.
