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.

Display device, method for manufacturing the device and laser processing apparatus for manufacturing the display device

A display device including a base substrate including a display area and a non-display area positioned at a side of the display area; at least one transistor in the display area of the base substrate and conductive lines in the non-display area of the base substrate; at least one light-emitting element in the display area that is coupled to the at least one transistor; an encapsulation layer covering the light-emitting element; a sensing electrode on the encapsulation layer and a sensing line on the encapsulation layer coupled to the sensing electrode; and an align mark on the encapsulation layer at least partially overlapping some of the conductive lines in the non-display area, in a plan view.

Display device having an align mark to facilitate assembly of layers during manufacture

A display device includes: a base substrate including a display area and a non-display area positioned at a side of the display area; at least one transistor in the display area of the base substrate and conductive lines in the non-display area of the base substrate; at least one light-emitting element in the display area that is coupled to the at least one transistor; an encapsulation layer covering the light-emitting element; a sensing electrode on the encapsulation layer and a sensing line on the encapsulation layer coupled to the sensing electrode; and an align mark on the encapsulation layer at least partially overlapping some of the conductive lines in the non-display area, in a plan view.

A display device and a method configured to inspect alignment in which the display device includes a substrate having a hole, a non-display area surrounding the hole, and a display area surrounding the non-display area; a display unit disposed on the substrate and having pixels disposed in the display area; and sensing electrodes disposed in the display area and a first alignment mark disposed in the non-display area on the display unit.

Display device and method for inspecting alignment

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.

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.
