Title:
GLASS SUBSTRATE AND ELECTRONIC DEVICE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/097537
Kind Code:
A1
Abstract:
This rectangular glass substrate 1 has first edges 1y parallel to a sheet-pulling direction Y and second edges 1x parallel to a width direction X. The length of the second edges 1x is 1500 mm or more. The thickness of the glass substrate is 1.3 mm or less. When seven rectangular evaluation regions A, B, C, D, E, F, and G having the same size are sequentially set from one end side in the width direction X so as to obtain a positional relationship in which the respective regions are separated by an equal interval L in the width direction X, the average ΔHC-E of obverse-reverse flexure difference Y1-Y2 of the evaluation regions C, D, and E in the sheet-pulling direction Y is negative.
