Abstract

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.

Claims

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 coated on the second surface of the window.

2. The device of claim 1, wherein the anti-reflection layer includes an anti-reflection (AR) coating.

3. The device of claim 2, wherein the anti-reflection layer includes a plurality of layers having different refractive indexes.

4. The device of claim 2, wherein the anti-reflection layer includes a plurality of laminated layers that have different thicknesses.

5. The device of claim 2, wherein the anti-reflection layer includes a layer that includes titanium oxide TiO₂, and a layer that includes silicon oxide SiO₂.

6. The device of claim 1, further comprising a fingerprint prevention layer coated on the anti-reflection layer.

7. The device of claim 6, wherein the fingerprint prevention layer includes an anti-fingerprint (AF) coating.

8. The device of claim 6, wherein the fingerprint prevention layer includes fluorine (F).

9. The device of claim 6, wherein the total thickness of the anti-reflection layer and the fingerprint prevention layer is in the range of about 1600 to 2200 Å

.

10. The device of claim 6, further comprising a polarizer positioned between the display panel and the window.

11. The device of claim 10, further comprising an adhesive layer positioned between the polarizer and the window.

12. The device of claim 1, wherein the display panel includes liquid crystals or an organic light emitting diode.
