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 display device including a linear portion and a curved portion, including a first substrate including a first surface and a second surface opposite the first surface; a second substrate including a third surface and a fourth surface opposite the third surface; and a display panel disposed between the first surface of the first substrate and the fourth surface of the second substrate. An outer surface adjacent to the first surface of the first substrate protrudes outward from an outer surface adjacent to the second surface of the first substrate, and a first width of a region of the first surface of the first substrate that does not overlap with the second surface in the linear portion is greater than a second width of a region of the first surface of the first substrate that does not overlap with the second surface of the first substrate in the curved portion.
