- at least a part of the peripheral portion 22 may precipitate on the glass substrate surface (one surface of the glass substrate and / or the other surface) as a substantially thread-like precipitate 31 as shown in FIG. is there. This is because glass has a low thermal conductivity, and therefore a temperature gradient is generated in the peripheral portion 22 in the cooling step after the heating step. Therefore, at least the peripheral portion 22 is formed on the glass substrate by the stress generated in the peripheral portion 22. It is inferred that a part is excluded and precipitates.

- the A evaluation is distributed in a range surrounded by the straight line X and the straight line Y.
- the C evaluation is performed, and when the transport speed is slower than the straight line Y, the B evaluation is performed. It has become.
- the glass substrate in the laser light irradiation area This is considered to be because the laser beam irradiation part from one surface of the glass to the other surface can be reliably heated to a temperature higher than the temperature at which the glass vaporizes.
- the peripheral part of the laser light irradiation part after laser light irradiation can be sufficiently cooled and removed from the cut surface part as a precipitate, so that the cut surface with uniform surface characteristics. It is thought that it can be.
- the glass substrate that has been evaluated as C sufficient energy of the laser beam cannot be imparted with respect to the relative movement speed of the irradiation region of the laser beam with respect to the glass substrate (the conveyance speed of the glass substrate).
- the region it is considered that the other surface of the glass substrate could not be heated to a temperature higher than the temperature at which the glass vaporizes (the temperature could not be sufficiently raised in the entire range in the thickness direction of the glass substrate). For this reason, it is estimated that the glass substrate could not be cut.
- the relative movement speed of the laser light irradiation area with respect to the glass substrate is not sufficient, and the cooling speed of the peripheral part of the laser light irradiation part after laser light irradiation becomes slow, and the peripheral part is deposited. It is assumed that the cut surface did not become uniform because it was not excluded as a product. Or, when the temperature of the peripheral part of the laser light irradiation part after laser light irradiation is cooled by transporting the glass substrate, it is not the desired cooling rate, so that the cut surface and its periphery are cracked It is inferred.
- the energy density of the laser light can be appropriately selected for the A-evaluated glass substrate in accordance with the relative movement speed (glass substrate transport speed) of the laser light irradiation region with respect to the glass substrate. For this reason, it is considered that the laser beam irradiation region is heated from one surface of the glass substrate to the other surface at a temperature higher than the temperature at which the glass is vaporized. Furthermore, since the conveyance speed of the glass substrate is appropriate, the peripheral part of the laser light irradiation part after the laser light irradiation is cooled at an appropriate cooling rate, and the peripheral part of the laser light irradiation part after the laser light irradiation is a precipitate.

- the straight line Y indicates the minimum value of the relative movement speed (here, the conveyance speed of the glass substrate) of the irradiation region of the laser beam, in which the precipitate is generated in the cooling process, and in this case, 144 (m / hour) )Met.
- FIG. 3 In this experimental example, the energy density of the laser beam and the relative movement speed of the irradiation region of the laser beam with respect to the glass substrate are changed in the same manner as in Experimental Example 1 except that the thickness of the glass substrate to be cut is 0.3 mm. Then, the glass substrate was cut, and the cut surface of the glass substrate after cutting was evaluated.
- FIG. 6 is a graph of the results in Table 3.
- the straight line Y indicates the minimum value of the relative movement speed (here, the conveyance speed of the glass substrate) of the irradiation region of the laser beam, in which the precipitate is generated in the cooling process, and in this case, 144 (m / hour) )Met.
- the glass substrate is cut by changing the energy density of the laser beam to be irradiated without changing the conveyance speed of the glass substrate.
- the energy density of the laser beam is increased to be higher than the straight line X
- the glass is vaporized in the laser beam irradiation area from one surface of the glass substrate to the other surface in the laser beam irradiation region. It was possible to heat to a temperature higher than the temperature to be evaluated, and it was confirmed that the evaluation was A.
- Example 4 In this experimental example, the energy density of the laser beam and the relative movement speed of the irradiation region of the laser beam with respect to the glass substrate are changed in the same manner as in Experimental Example 1 except that the thickness of the glass substrate to be cut is 0.6 mm. Then, the glass substrate was cut, and the cut surface of the glass substrate after cutting was evaluated.

For this reason, sufficient energy of the laser beam cannot be applied to the relative movement speed of the laser beam irradiation area with respect to the glass substrate (the conveyance speed of the glass substrate), and the other surface of the glass substrate with respect to the laser light irradiation area It is considered that the glass substrate could not be heated to a temperature higher than the temperature at which it vaporizes. Therefore, it was considered that C evaluation was made because the glass substrate could not be cut.
