Zusammenfassung:	Disclosed are a laser processing device used to process display panels of various sizes and shapes and a laser processing method using the laser processing device. The laser processing method according to one embodiment rotates a workpiece including a processing area, creates angle and distance values by setting polar coordinates according to the rotation of the workpiece, and sets the generated distance value as the processing coordinate of the laser beam. Since the laser beam reciprocates between the rotating workpiece and the straight laser beam path, there is an effect of enabling laser processing with a single optical unit regardless of the size of the workpiece. 다양한 크기 및 형태의 표시 패널을 가공하는데 사용하는 레이저 가공 장치 및 그 레이저 가공 장치를 이용한 레이저 가공 방법을 개시하며, 일 실시예들에 의한 레이저 가공 방법은 가공 영역을 포함하는 피가공물 회전시키고, 피가공물의 회전에 따른 극좌표를 설정하여 각도값 및 거리값을 생성하고, 생성된 거리값을 레이저 빔의 가공 좌표로 설정하여 회전하는 피가공물과 직선의 레이저 빔 이동 경로를 왕복 운동하는 레이저 빔에 의해 피가공물의 크기에 관계없이 단일의 광학 유닛으로 레이저 가공이 가능한 효과를 제공한다.
