A device for attaching a protective film to a display of a smart device according to the present invention comprises: a protective film attaching frame (10) wherein lower and upper surfaces are opened to expose a display surface and a lower surface of a smart device, and a jack recess (11) and a button recess (12) are formed on a side strap (13) thereof; a protrusion dam (20) protruding horizontally from an inner wall of an upper portion of the attaching frame (10) to cover a thickness portion of a side wall (3) of the smart device (1) to expose only the display surface (2) of the smart device (1) to guide a protective film (30) to a right position of the display surface (2); and an air discharge hole (25) formed by cutting a portion of the protrusion dam (20) to discharge air to an edge surface of the protective film (30) after the film is attached. One set of corners of the attaching frame (10) are square corners (10a), and the other set of corners opposing the one set of corners are round corners (10b). The air discharge hole (25) is formed on the round corners (10b), where the protrusion dam (20) is absent. A vertical slit (15) is formed on a lower end of the round corners (10b) in a horizontal direction corresponding to a lower surface of the protrusion dam (20) to spread an internal space of the side strap (13). |
