  • Method for repairing glass substrate, process for producing glass substrate, glass substrate, and flat panel display
    Patent number: 8395747
    Abstract: A method for repairing a glass substrate is a method for repairing a glass substrate (10) having a depression (60) formed in a display region (5). Into the depression (60), 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 (60) in a surface of the glass substrate (10) is repaired by a transparent resin (65) obtained through the copolymerization of the plural types of starting material. Therefore, the glass substrate (10) can be repaired at a low temperature without performing a sintering process.
