Abstract: A method of manufacturing a display device, including: providing an object to be processed; forming a linear portion of the object to be processed by performing a first laser processing for the object to be processed; and forming a curved portion of the object to be processed by performing a second laser processing different from the first laser processing for the object to be processed. A laser processing apparatus, is also provided, including: an irradiation unit applying a laser onto an object to be processed; and a controller controlling an operation of the irradiation unit. The controller controls the irradiation unit to form a linear portion of the object to be processed by applying the laser onto the object according to a first condition and forming a curved portion of the object by applying the laser onto the object according to a second condition different from the first condition.

Abstract: A patterning apparatus includes a laser generator, at least one lens, a detector, and a controller. The laser generator generates a first laser beam and a second laser beam having different intensities. The at least one lens irradiates the first laser beam to form a pattern in a substrate, irradiates a second laser beam to determine a defect of the pattern, and condenses reflected beams generated as the second laser beam is reflected from the substrate. The detector converts the reflected beams to electrical signals. The controller determines a defect of the pattern based on the electrical signals.
