Document Type and Number:

WIPO Patent Application WO/2024/018690

Kind Code:

A1

Abstract:

This glass panel unit manufacturing method facilitates an improvement in productivity and quality. In an arrangement step S1, a first glass substrate 1 and a second glass substrate 2 are arranged facing each other across a seal member 3 formed at a plurality of places. In a joining step S2, the first glass substrate 1 and the second glass substrate 2 are joined together with the seal member 3 interposed therebetween. In a cutting step S4, the first glass substrate 1 and the second glass substrate 2 are cut at the same position when seen from a direction in which the first substrate 1 and the second glass substrate 2 face each other, and along the seal member 3. Furthermore, a plurality of pairs of the first glass substrate 1 and the second glass substrate 2 that have been cut are respectively cut at a plurality of places where the seal member 3 could be positioned along an edge. Furthermore, in at least some among the plurality of places where the first glass substrate 1 and the second glass substrate 2 are cut, one of the first glass substrate and the second glass substrate 2 is selected and cut from the front surface side, and thereafter, the other of the first glass substrate and the second glass substrate 2 is cut from the front surface side.
