Display device

A laser cutting apparatus includes a laser module, a vibration module, a motor module, a reflective module, and a concentrating module. The vibration module includes a lens module, and a piezoelectric module coupled to the lens module and configured to repeatedly expand and contract. The motor module is configured to move the vibration module in by transmitting power to the vibration module. The reflective module is configured to reflect the laser beam in such a way that a traveling direction of the laser beam is changed. The concentrating module is configured to concentrate the laser beam in such a way that energy of the laser beam reflected by the reflective surface is concentrated at a focal point.
