Abstract: A glass sheet cutting device fuses and divides a glass substrate using a preset cutting line as a boundary while supplying an assist gas and a laser beam from above the glass substrate along the preset cutting line of the glass substrate. The glass sheet cutting device includes a first laser irradiator for radiating a fusing laser beam and a second laser irradiator for radiating an annealing laser beam. Through a fusing gap formed between fused end surfaces by fusing, the second laser irradiator radiates the annealing laser beam obliquely from above onto the fused end surface to be annealed.
