Title:
HIGH-STRENGTH GLASS, TOUCH PANEL, AND METHOD FOR MANUFACTURING HIGH-STRENGTH GLASS
Document Type and Number:
WIPO Patent Application WO/2013/088755
Kind Code:
A1
Abstract:
[Problem] To provide a high-strength glass in which damage such as cracking due to microcracking or the like can be prevented, the time required for treatment for maintaining strength can be shortened, production efficiency can be improved, and the end surfaces can be formed to a desired shape. [Solution] A reinforcement layer (2) is formed on both surfaces of a glass plate (1), and a protective film (3) is formed on regions excluding cut sections (4). Next, recesses (7) obtained by corrosion through an etching treatment are formed on the cut sections (4) of the glass plate (1) not covered by the protective film (3). Then, a hole is formed using a cutting machine (8b) at the opening sections (4b), and peripheral edge sections (4a) are cut using a cutting machine (8a) to obtain diced high-strength glass (10). A stepped section (11) having a convex cross section and comprising an inner side surface (12) obtained by corrosion through an etching treatment and an outer side surface (13) cut by mechanical machining is formed at the peripheral edge end surface (1a) and opening end surface (1b) of the glass plate (1). Since the end surface of the stepped section (11) is mechanically machined, the end surface can be machined to a desired shape.
