GLASS SUBSTRATE AND METHOD FOR MANUFACTURING SAME

摘要

Provided is a glass substrate (1) having the front surface (2a), the rear surface (2b), and the edge surface (3b) between the outer circumferential ends of the both surfaces (2a, 2b). A chamfered surface (4) is formed on the boundary section between the front surface (2a) and/or the rear surface (2b) and the edge surface (3b), the ten-point average roughness (Rz2) of the chamfered surface (4) is smaller than the ten-point average roughness (Rz1) of the edge surface (3b), and the average length (RSm2) of the roughness curve elements of the chamfered surface (4) is longer than the average length (RSm1) of the roughness curve elements of the edge surface. Preferably, the ten-point average roughness (Rz2) of the chamfered surface (4) and the ten-point average roughness (Rz1) of the edge surface (3b) satisfy the inequalities of Rz1=1.5 and 1.5<=Rz1/Rz2<=10.0.
