Abstract: A display device and a method of manufacturing a display device are provided. A manufacturing method of a display device includes: forming a display module including a first area defined therein, the display module including a display panel including a lower surface and an upper surface opposite the lower surface, a first film under the lower surface of the display panel, a second film on the upper surface of the display panel, and an adhesive layer between the lower surface of the display panel and the first film; and irradiating a laser beam in an upper direction extending from the lower surface of the display panel to the upper surface of the display panel to cut the first film and the adhesive layer along an edge of the first area, the laser beam provided to the display panel having a laser power equal to or less than about 1 W.

Abstract: A display device and a method of manufacturing a display device are provided. A manufacturing method of a display apparatus includes forming a display module including a first area and including a display panel including lower and upper surfaces opposite each other, a first film under the lower surface of the display panel, a second film on the upper surface of the display panel, and an adhesive layer between the lower surface of the display panel and the first film; weakening an adhesive force of a first adhesive portion of the adhesive layer in the first area to be weaker than an adhesive force of a second adhesive portion of the adhesive layer outside the first area; cutting the first film and the adhesive layer; and removing a portion of the first film and the first adhesive portion from the first area.

Abstract: A method of manufacturing a flexible display is disclosed. In one aspect, the method includes forming a display panel including first and second sides opposing each other, wherein the display panel includes a plurality of cells in a mother substrate form, and wherein each of the cells includes a display unit. The method also includes attaching a first protection film on the first side of the display panel via a first adhesive layer and attaching a second protection film on the second side of the display panel via a second adhesive layer. The method further includes irradiating laser light having a first wavelength between the cells so as to cut the display panel into the cells. Each of the first and second adhesive layers includes an absorber configured to absorb light having the first wavelength.
