Abstract: A method of manufacturing a display apparatus includes preparing a panel with a panel layer displaying images, a first protection film on a first surface of the panel layer with a first adhesion layer, and a second protection film on a second surface of the panel layer with a second adhesion layer, disposing the panel on a stage, cutting the panel on the stage along a closed-curve line to a predetermined depth extending from the second protection film to at least a portion of the first adhesion layer, and separating a first portion of the panel inside the closed-curve line from a second portion of the panel outside the closed-curve line, such that the second portion is removed simultaneously with the entire first protection film according to a first boundary by the line and a second boundary between the panel layer and the first protection film.

Abstract: A display device according to embodiments of the present disclosure includes a display panel, a protection member to protect the display panel, and an adhesive member between the display panel and the protection member to couple the display panel to the protection member. The display panel may include a plurality of pixels to display an image, and the adhesive member may include an adhesive agent and an anti-static agent dispersed in the adhesive agent. The anti-static agent may include halogen ions, and a content of halogen ions with respect to a total weight of the adhesive agent may be within a range (e.g., from about 1 ppm to about 1000 ppm) capable of reducing stain failures caused by static electricity, without causing corrosion of driving lines in the display.
