說明書
An embodiment provides an electronic device including 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.
In an embodiment, the polyimide film may include biphenyl-tetracarboxylic acid dianhydride (“BPDA”) and a filler.
In an embodiment, the filler may have a size of about 0.5 micrometer (μm) or more and about 2 μm or less.
In an embodiment, each of the first anti-static layer and the second anti-static layer may include a urethane-based binder.
In an embodiment, each of the first anti-static layer and the second anti-static layer may include isocyanate.
In an embodiment, the first surface of the protection film may have a polar surface energy of about 12 millinewtons per meter (mN/m) or more.
In an embodiment, the first surface of the protection film may have a surface resistance of about 106 Ohms per square (Ω/□) or less.
In an embodiment, a top surface of the adhesive layer which is attached to the rear surface of the display panel, may have a surface resistance of about 109Ω/□ or more and about 1011Ω/□ or less.
