Display device
An exemplary embodiment provides a display device that includes: a display panel; a window positioned on the display panel; and an anti-reflection layer coated on the window.
1. A display device, comprising:
a display panel;
a window positioned on the display panel, having a first surface that faces the display panel and an opposing second surface; and
an anti-reflection layer on the second surface of the window, the anti-reflection layer including an anti-reflection coating having a plurality of layers, the plurality of layers having different thicknesses, wherein:
the plurality of layers includes a first layer, a second layer, a third layer, and a fourth layer in that order from the window, and
the third and fourth layers are each thicker than a combined thickness of the first and second layers.
2. The device of claim 1 , wherein the plurality of layers have different refractive indexes.
3. The device of claim 1 , wherein the first layer includes titanium oxide TiO 2 , and the second layer includes silicon oxide SiO 2 .
4. The device of claim 1 , further comprising a fingerprint prevention layer on the anti-reflection layer.
5. The device of claim 4 , wherein the fingerprint prevention layer includes an anti-fingerprint (AF) coating.
6. The device of claim 4 , wherein the fingerprint prevention layer includes fluorine (F).
7. The device of claim 4 , wherein the total thickness of the anti-reflection layer and the fingerprint prevention layer is in the range of about 1600 to 2200 Å.
8. The device of claim 4 , further comprising a polarizer positioned between the display panel and the window.
9. The device of claim 8 , further comprising an adhesive layer positioned between the polarizer and the window.
10. The device of claim 1 , wherein the display panel includes liquid crystals or an organic light emitting diode.
11. The device of claim 1 , further comprising a fingerprint prevention layer having a thickness of less than about 300 angstroms.
12. The device of claim 8 , wherein there are substantially no air gaps between the window and the display panel.
13. The device of claim 1 , wherein a surface of the anti-reflection layer has an irregular pattern.
