Abstract:
A method of manufacturing a glass sheet involves forming a scribe in one surface of a glass sheet having a rectangular shape on a periphery of an edge portion of the glass sheet in parallel to the edge portion, and cutting the glass sheet along the scribe as a boundary. The method includes forming the scribe in a region other than both end portions of the glass sheet in a direction along the edge portion; and cutting the glass sheet along a bending portion in which the glass sheet is locally bent, the bending portion being continuously formed in a state of being connected to the scribe and gradually protruding from an edge portion side to an inner side as being shifted away from the scribe.
