Abstract

An anti-reflection film and a display device including the same, and a manufacturing method of an anti-reflection film and a master film therefor. The anti-reflection film includes an anti-glare and anti-reflection layer, a surface of the anti-glare and anti-reflection layer having an anti-glare pattern for scattering incident light and an anti-reflection pattern.

Claims

1. An anti-reflection film comprising an anti-glare and anti-reflection layer,

a surface of the anti-glare and anti-reflection layer having an anti-glare pattern for scattering incident light and an anti-reflection pattern, wherein

the anti-glare pattern comprises irregular protrusions and depressions of several tens to several hundreds of nanometers;

and

the anti-reflection pattern comprises a pattern having from two to five protrusions and depressions per micrometer.

2. The anti-reflection film of claim 1, wherein the anti-reflection pattern comprises regular protrusions and depressions.

3. The anti-reflection film of claim 2, wherein intervals between the protrusions and depressions of the anti-glare pattern are greater than intervals between the protrusions and depressions of the anti-reflection pattern.

4. The anti-reflection film of claim 1, wherein the anti-reflection pattern comprises a moth-eye pattern.

5. The anti-reflection film of claim 4, wherein the moth-eye pattern comprises regularly arranged protrusions and depressions.

6. The anti-reflection film of claim 1, wherein the anti-reflection pattern is on the surface of the anti-glare pattern.

7. The anti-reflection film of claim 1, wherein the anti-glare and anti-reflection layer comprises an ultraviolet curable resin.

8. The anti-reflection film of claim 1, wherein the anti-reflection film further comprises a substrate positioned under the anti-glare and anti-reflection layer.

9. A display device comprising the anti-reflection film of claim 1.
