4 . The window of claim 1 , wherein the hard coating layer comprises a fluorine-based compound.
5 . The window of claim 1 , wherein a thickness of the hard coating layer is in a range of about 5 μm to about 20 μm.
6 . The window of claim 1 , wherein a thickness of the base layer is in a range of about 50 μm to about 100 μm.
7 . The window of claim 1 , further comprising:
an optical bonding layer disposed directly on a lower surface of the base layer, the optical bonding layer including a polyurethane resin.
8 . The window of claim 1 , wherein a haze of the window is in a range of about 1% or less.
9 . The window of claim 1 , wherein a modulus of the window is in a range of about 6 GPa or more.
10 . A display device comprising:
a display module;
a support module disposed below the display module;
a window disposed above the display module, the window including:
a base layer;
a hard coating layer disposed above the base layer, the hard coating layer integrally formed as a single layer; and
a bonding layer disposed between the base layer and the hard coating layer, the bonding layer including polysiloxane;
a folding area that is folded with respect to a folding axis extending in a direction; and
a non-folding area adjacent to the folding area,
wherein the hard coating layer and the base layer are bonded to each other via the bonding layer,
wherein the support module comprises a support plate including openings that correspond to the folding area,
wherein the base layer is a single glass substrate or a single polymer film, and
wherein the single polymer film is a polyimide film or a polyethyleneterephthalate film.
11 . The display device of claim 10 , wherein
a lower surface of the hard coating layer contacts the bonding layer, and
an upper surface of the hard coating layer is an uppermost surface of the window that is exposed to the outside.
12 . The display device of claim 10 , wherein the hard coating layer comprises a fluorine-based compound.
13 . The display device of claim 10 , wherein
the bonding layer further comprises 2-hydroxyethyl ester, and
a weight ratio of the polysiloxane to the 2-hydroxyethyl ester in the bonding layer is about 1:1.
14 . The display device of claim 10 , further comprising:
a window adhesive layer disposed between the display module and the window.
15 . A display device comprising:
a display module; and
a window disposed on the display module, the window including:
a base layer;
a hard coating layer that is disposed on an upper surface of the base layer, the hard coating layer being integrally as a single layer; and
a bonding layer disposed between the base layer and the hard coating layer and contacting the base layer and the hard coating layer, the bonding layer including polysiloxane and 2-hydroxyethyl ester, wherein
the hard coating layer and the base layer are bonded to each other via the bonding layer.
16 . The display device of claim 15 , wherein
a weight ratio of the polysiloxane to the 2-hydroxyethyl ester in the bonding layer is about 1:1.
