Abstract
A method for repairing a glass substrate is a method for repairing a glass substrate () having a depression () formed in a display region (). Into the depression (), plural types of starting material from which a cross-linked epoxy resin or a cross-linked (meth)acrylic resin is made are put together with a photoinitiator, and the starting materials thus put are copolymerized by light irradiation and heat treatment. In the result, the depression () in a surface of the glass substrate () is repaired by a transparent resin () obtained through the copolymerization of the plural types of starting material. Therefore, the glass substrate () can be repaired at a low temperature without performing a sintering process. Further, the transparent resin () has a reticular structure obtained through random copolymerization of the plural types of starting material and, as such, has its optical anisotropy suppressed, thus preventing the emergence of an unintended luminescent spot or the like on a liquid crystal display panel.
