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 protective film, a display device including the protective film and a method of manufacturing the protective film are provided. The protective film includes a urethane adhesive layer including a urethane adhesive resin, a base film layer on the urethane adhesive layer, and a hard coating layer on the base film layer and including a fluorine-based photocurable resin and a glycol-based photocurable resin.
