摘要

PROBLEM TO BE SOLVED: To provide a glass plate in which flaws and cracks formed on a glass substrate before FED to a production process or caused on the glass substrate in the process of the production process are removed, and the crack strength of the substrate is improved, to provide a method for producing the glass plate, to provide a glass substrate for an electrooptical panel, to provide a method for producing the glass substrate for the electrooptical panel, to provide the electrooptical panel, to provide a method for producing the electrooptical panel, and to provide electronic equipment. SOLUTION: A glass substrate is subjected to etching treatment (stage S1), and chemical strengthening treatment (stage S2). Flaws and cracks formed on the substrate are removed by the etching treatment. Further, its mechanical strength is improved by performing the chemical strengthening treatment in a state where the flaws and cracks are removed. COPYRIGHT: (C)2004,JPO
