In addition, since the lower luminescent plate and the laser generating device are not directly connected by the structure, there is no obstacle in cutting the glass, and thus cutting is possible regardless of the size of the glass.

Seventh, by mounting the bending portion higher than the upper surface of the stage, the glass can be arranged to be inclined downward to both sides, so that the stress can be concentrated in the center portion of the glass to be cut.

In particular, by attaching the bent portion to the rear of the lower luminescent plate, the bent portion may push the glass to the upper side to make it easier to cut the glass.

Eighth, by forming an air inlet in the stage, it is possible to prevent the glass from being pushed, and to bend the central portion of the glass, that is, the portion of the glass to be cut together with the bent portion, so that the stress concentration is reduced, the less energy The glass can be easily cut with
