Abstract: In a method for manufacturing a display device, the method includes: providing a display panel divided into a cutting area and a body part surrounding the cutting area; attaching a dummy film on a bottom surface of the display panel; cutting the cutting area by irradiating laser light toward a cutting line defined as a boundary between the cutting area and the body part; irradiating the laser light to a groove line of the dummy film, which overlaps the cutting line, to define a groove in the dummy film along the groove line; and separating the dummy film from the body part.

Abstract: A method for manufacturing a display module includes preparing a display module comprising a plurality of layers and forming a through-hole in the display module. The forming the through-hole includes performing a first irradiation process of irradiating a first laser beam along a first boundary defining the through-hole, performing a second irradiation process of irradiating a second laser beam along a second boundary after the first irradiation process, and performing a third irradiation process of irradiating a third laser beam along a third boundary after the second irradiation process. A time interval between the first irradiation process and the second irradiation process may be different from a time interval between the second irradiation process and the third irradiation process.

Abstract: A method for testing a display module may include providing light to the display module, obtaining an image of the display module, measuring a first center of a hole in the display module, measuring a first distance from the first center to an edge of the hole, measuring a second center of a closed line formed by a signal line of the display module, measuring a second distance from the second center to the signal line, calculating a third distance between the first center and the second center, and comparing the second distance with a sum of the first distance and the third distance.
