GLASS RIBBON AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a glass ribbon which enables it to be bent with a large curvature while avoiding stress concentration to the edge thereof.

SOLUTION: The glass ribbon 1 has a thickness of ≤100 μm and has a convex curved portion 4 on the side face thereof. The glass ribbon 1 is produced by heating a preform glass material having a thickness of ≤2 mm and subjecting the preform glass material to drawing until the thickness of the stretched material reaches 100 μm or less.
