The color of the protective film 600 may be the same color as the color of the adhesive 113 . Since the color of the protective film 600 is of the same series as that of the adhesive 113, a color difference occurs between the area overlapping the hole h1 of the display panel 110 and the area not overlapping the hole h1. can be restrained

In addition, one surface of the protective film 600 may be white or gray and the other surface may be black. In this case, the color of the adhesive 113 may be the same color as the one surface of the protective film 600 , and may be white or gray. One surface of the white or gray protective film 600 reflects or minimizes light emitted from the display panel 110 through the hole h1 , thereby preventing it from being irradiated to the outside. In addition, the other surface of the black protective film 600 may block light irradiated to the display panel 110 through the hole h1 from the outside.

In addition, the protective film 600 may include an insertion part 601 inserted into the hole h1 and a cover 602 attached to one end of the insertion part 602 and not inserted into the hole h1 .

Accordingly, light emitted from the display panel 110 may be reflected or absorbed by the adhesive 113 may be minimized. When the amount of light emitted from the display panel 110 reflected or absorbed by the adhesive 113 is reduced, the decrease in the luminance of the display panel 110 by the adhesive 113 may be minimized. In addition, the adhesive 113 may be a pressure sensitive adhesive (PSA). However, the adhesive 113 is not limited thereto.
