Title:
METHOD FOR CUTTING MOTHER GLASS SUBSTRATE FOR DISPLAY AND BRITTLE MATERIAL SUBSTRATE AND METHOD FOR MANUFACTURING DISPLAY
Document Type and Number:
WIPO Patent Application WO/2010/044217
Kind Code:
A1
Abstract:
Provided is a method for cutting a mother glass substrate (1) of a display panel which includes a first glass substrate (G1) and a second glass substrate (G2) bonded by sealing members (5) that define multiple cells arranged in a matrix. In a first step, a scribe line is formed on the first glass substrate (G1) by disposing a predetermined machining line (L1) in a gap between the sealing members (5) of adjacent cells and irradiating the first glass substrate (G1) with a laser along the predetermined machining line (L1). In a second step, the second glass substrate (G2) is cleaved by irradiating the second glass substrate (G2) with a laser along the predetermined machining line (L1) and cooling the neighborhood of a region (40) irradiated with the laser. Stress generated when the second glass substrate (G2) is cleaved is transmitted to the first glass substrate (G1) via the sealing members (5), whereby the first glass substrate (G1) is cleaved along the scribe line substantially simultaneously with the cleavage of the second glass substrate (G2).
