Display device
A display device includes a protective layer facing a display panel with a window therebetween, and the protective layer includes in order from the window: a base layer; and a surface coating layer having a single film structure. The surface coating layer includes an impact resistance layer and an anti-fingerprint material within the impact resistance layer.
1 . A display device comprising:
a display panel which generates an image and includes an active area at which the image is displayed;
a window facing the display panel and through which the image is transmitted, the window including a glass material; and
a protective layer facing the display panel with the window therebetween,
wherein
each of the display panel, the window and the protective layer includes opposing sidewalls facing each other, and
in a direction along the display panel, the opposing sidewalls of the window are closer to the active area than the opposing sidewalls of the display panel and the opposing sidewalls of the protective layer, respectively.
2 . The display device of claim 1 , wherein the protective layer, the window and the display panel are foldable and unfoldable.
3 . The display device of claim 2 , wherein the protective layer comprises in order from the window:
a base layer; and
a surface coating layer having a single film structure,
wherein the surface coating layer comprises an impact resistance layer.
4 . The display device of claim 3 , wherein the window has a thickness of about 80 micrometers or less.
5 . The display device of claim 4 , wherein the surface coating layer has a thickness of about 3 micrometers to about 10 micrometers.
6 . The display device of claim 5 , wherein the surface coating layer has a surface contact angle of about 100 degrees to about 120 degrees.
7 . The display device of claim 1 , wherein
a sidewall among the opposing sidewalls of the window is spaced apart from a corresponding sidewall among the opposing sidewalls of the protective layer by a first width, and
the first width is about 196 micrometers to about 300 micrometers.
8 . The display device of claim 1 , further comprising an adhesive layer between the display panel and the window,
wherein the adhesive layer faces the protective layer with the window therebetween.
9 . The display device of claim 8 , wherein
the adhesive layer includes a sidewall, and
in the direction along the display panel, the sidewall of the adhesive layer is closer to the active area than the corresponding sidewall of the protective layer.
10 . The display device of claim 9 , wherein
a sidewall among the opposing sidewalls of the window is spaced apart from a corresponding sidewall among the opposing sidewalls of the protective layer by a first width,
the sidewall of the adhesive layer is spaced apart from the corresponding sidewall of the protective layer by a second width, and
the second width is greater than or equal to the first width.
11 . The display device of claim 10 , wherein
the second width is greater than the first width,
the first width is about 196 micrometers to about 300 micrometers, and
the second width is about 292 micrometers to about 492 micrometers.
12 . The display device of claim 1 , wherein the protective layer has an elastic modulus of about 4.0 gigapascals to about 5.5 gigapascals.
13 . The display device of claim 12 , wherein
the protective layer includes an optical axis control stretched film including:
a first stretch axis having an elastic modulus, and
a second stretch axis having an elastic modulus, and
a difference between the elastic modulus along the first stretch axis and the elastic modulus along the second stretch axis is less than about 2 gigapascals.
14 . The display device of claim 3 , wherein the base layer comprises:
a base material; and
an ultraviolet light blocking material within the base material.
15 . The display device of claim 14 , wherein the protective layer has a transmission of less than about 20% with respect to ultraviolet rays having a wavelength of about 380 nanometers or less.
16 . The display device of claim 15 , wherein the base layer has a thickness of about 40 micrometers to about 70 micrometers.
17 . The display device of claim 3 , wherein the surface coating layer further comprises an anti-fingerprint material which is within the impact resistance layer.
18 . The display device of claim 17 , wherein the anti-fingerprint material has a weight ratio of greater than 0 weight percent to about 10 weight percent or less, with respect to a total weight of the surface coating layer.
19 . The display device of claim 17 , wherein the anti-fingerprint material comprises a water-repellent material or an oil-repellent material.
20 . The display device of claim 7 , wherein the first width is greater than thickness of the window.
