Abstract

Provided is an anti-glare/antireflection member having excellent visibility. The anti-glare/antireflection member ( 1 ) includes a base material ( 10 ) and an antireflection layer ( 20 ). The base material ( 10 ) is provided in a surface layer thereof with an anti-glare layer ( 10 a ) having a concavo-convex configuration. The antireflection layer ( 20 ) is provided on the anti-glare layer ( 10 a ).

First claim

The invention claimed is:

1. An anti-glare/antireflection member comprising:
a base material provided in a surface layer thereof with an anti-glare layer having a concavo-convex configuration; and
an antireflection layer provided on the anti-glare layer; wherein
the base material includes:
a base material body formed of a glass plate; and
the anti-glare layer consisting of an island layer made of one of SiO 2 , TiO 2 , Al 2 O 3 , and ZrO 2 disposed on the base material body; and

the antireflection layer is formed of a structure in which low-refractive index layers having a relatively low refractive index and high-refractive index layers having a relatively high refractive index are alternately disposed.

2. The anti-glare/antireflection member according to claim 1 , further comprising, on a surface of the base material opposite to the antireflection layer, another antireflection layer.

3. The anti-glare/antireflection member according to claim 1 , further comprising an antifouling layer containing fluorine and provided on the antireflection layer.

4. A method for producing the anti-glare/antireflection member according to claim 1 , wherein a light-transmissive material is applied on a surface of a light-transmissive plate by spraying to form the island layer thereon, thus preparing the base material composed of the light-transmissive plate and the island layer.

5. The anti-glare/antireflection member according to claim 1 , wherein the glass plate is made of a chemically tempered glass substrate.
