Abstract
A display device includes a display panel, a protection film which faces the display panel and includes a first surface closest to the display panel and a second surface which is opposed to the first surface, a first anti-static layer which defines the first surface of the protection film, a second anti-static layer which faces the first anti-static layer and defines the second surface of the protection film, and a polyimide film between the first anti-static layer and the second anti-static layer, and an adhesive layer which forms an interface with the first surface of the protection film and attaches the protection film to the display panel.
Claims18
An electronic device comprising:
- a display panel;
- a protection film which faces the display panel, the protection film comprising:
- a first anti-static layer which defines a first surface of the protection film which is closest to the display panel;
- a second anti-static layer which faces the first anti-static layer and defines a second surface of the protection film which is opposed to the first surface;
- a polyimide film between the first anti-static layer and the second anti-static layer;
- the first surface of the protection film which is defined by the first anti-static layer having a surface resistance and a polar surface energy of about 12 millinewtons per meter or more and about 22 millinewtons per meter or less;
- and
- the polyimide film having a surface resistance and a surface energy of about 39 millinewtons per meter or more;
- and
- an adhesive layer which forms an interface with the first surface of the protection film and attaches the protection film to the display panel, the adhesive layer having a top surface which forms an interface with the display panel and has a surface resistance,
- wherein
- the surface resistance of the polyimide film is greater than the surface resistance of the first surface of the protection film, and
- the surface resistance of the top surface of the adhesive layer is greater than the surface resistance of the first surface of the protection film and lower than the surface resistance of the polyimide film.
An electronic device comprising:
- a display panel;
- a protection film which faces the display panel;
- and
- an adhesive layer which attaches the display panel to the protection film and comprises a top surface which forms an interface with the display panel and has a surface resistance,
- wherein the protection film comprises:
- a first anti-static layer which is directly attached to the adhesive layer, defines a first surface of the protection film, the first anti-static layer comprising:
- a first binder including a first anti-static material;
- a first surface of the first anti-static layer which is closest to the display panel, directly attached to the adhesive layer and has a surface resistance, and
- the first surface of the first anti-static layer which is directly attached to the adhesive layer having a polar surface energy of about 12 millinewtons per meter or more and about 22 millinewtons per meter or less;
- a base film facing the adhesive layer with the first anti-static layer therebetween and having a surface resistance;
- the base film having a surface energy of about 39 millinewtons per meter or more,
- wherein
- the surface resistance of the base film is greater than the surface resistance of the first surface of the first anti-static layer, and
- the surface resistance of the top surface of the adhesive layer is greater than the surface resistance of the first surface of the first anti-static layer and lower than the surface resistance of the base film.
