Glass plate manufacturing method, glass plate, and glass plate package
A method for manufacturing a glass plate includes a cutting step (S3) for removing an end portion (Ga) in the width direction of a glass plate (G1) in a state in which the glass plate (G1) is supported in a vertical orientation. The cutting step (S3) includes a scribing step and a breaking step. In...

| description | A method for manufacturing a glass plate includes a cutting step (S3) for removing an end portion (Ga) in the width direction of a glass plate (G1) in a state in which the glass plate (G1) is supported in a vertical orientation. The cutting step (S3) includes a scribing step and a breaking step. In the scribe step, the scribe line (SL2) is formed such that the maximum depth of the median crack (MC) in the middle portion (MP1) of the scribe line (SL2) is shallower than the maximum depth of the median crack (MC) in the lower portion (BP1) of the scribe line (SL2).
玻璃板的制造方法包括在将玻璃板（G1）以纵姿态支承的状态下将玻璃板（G1）的宽度方向的端部（Ga）去除的切断工序（S3）。切断工序（S3）包括刻划工序以及折断工序。在刻划工序中，以刻划线（SL2）的中间部（MP1）的中位裂纹（MC）的最大深度比刻划线（SL2）的下部（BP1）的中位裂纹（MC）的最大深度浅的方式形成刻划线（SL2）。 |
