GLASS SUBSTRATE FOR FLAT PANEL DISPLAY AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a glass substrate in which such a situation that a formation failure such as a disconnection failure is caused at a pattern electrode can be reliably prevented.

SOLUTION: In a glass substrate 1 formed by a float method, when a central region excluding a region within 10 mm from the circumference on at least one surface of the substrate is defined as an effective surface 2, any position in the effective surface has an arithmetic average roughness Ra of 0.3 nm or less and a ten-point average roughness Rzjis of 40 nm or less.
