Abstract

Disclosed is an anti-glare anti-reflection film having a low haze and reduced in unevenness and dazzle. The film contains a thermoplastic resin film and at least a hard coat layer and an anti-reflection layer provided on a first surface of the thermoplastic resin film. In the film, a first convexoconcave structure that can give an anti-glare property is provided on the first surface of the thermoplastic resin film or the surface of a layer provided on the first surface of the thermoplastic resin film, and a second convexoconcave structure that can give an anti-glare property is provided on a second surface which is the other surface of the thermoplastic resin film or the surface of a layer provided on the second surface of the thermoplastic resin film. The anti-glare anti-reflection film has an average film thickness of 20 to 70 μm.

Claims (21)

1. A method of manufacturing an anti-glare anti-reflection film comprising the steps of:

providing a hard coat layer on a first surface of a thermoplastic resin film; and

providing an anti-reflection layer on the hard coat layer, wherein

the method further comprises, the steps of:

providing a first convexoconcave structure which gives an anti-glare property on the first surface of the thermoplastic resin film or on the hard coat layer provided on the first surface, before providing the anti-reflection layer on the hard coat layer; and

providing a second convexoconcave structure which gives the anti-glare property on the second surface of the thermoplastic resin film or on a layer provided on the second surface, the second surface being a surface of the thermoplastic resin film opposite to the first surface, wherein

an average total thickness of the anti-glare anti-reflection film is 20 to 70 μm.

2. The method of claim 1 , wherein

the step providing the first convexoconcave structure and the step providing the second convexoconcave structure are each carried out by embossing with a roller having a convexoconcave structure.

3. The method of claim 1 , wherein

the hard coat layer and the anti-reflection layer are provided on the first surface of the thermoplastic resin film; and

the step of providing the first convexoconcave structure is carried out before the step of providing the hard coat layer.

4. The method of claim 1 , wherein

the hard coat layer and the anti-reflection layer are provided on the first surface of the thermoplastic resin film; and

the step of providing the first convexoconcave structure is carried out between the step of providing the hard coat layer and the step of providing the anti-reflection layer on the hard coat layer.

5. The method of claim 2 , wherein

a convexoconcave structure of a convexoconcave roller used to provide the first convexoconcave structure is formed by using a metallic material or a ceramic material; and

a convexoconcave structure of a convexoconcave roller used to provide the second convexoconcave structure is formed by using a rubber material.

6. The method of claim 2 , wherein

a convexoconcave structure of a convexoconcave roller used to provide the first convexoconcave structure is formed by using a rubber material; and

a convexoconcave structure of a convexoconcave roller used to provide the second convexoconcave structure is formed by using a metallic material or a ceramic material.
