Abstract
A display device antireflection filter 100 formed on a glass base material is comprised of an antireflection layer 102 of at least one layer containing SiO2 and a material layer 103 made of composition produced by adding compound whose interaction with SiO2 is small to compound having alkoxysilane group at terminal and which has perfluoropolyether group. This device exhibits improved wear and abrasion resistance.

In an antireflection filter for display device formed on a glass base material, said antireflection filter for display device characterized by at least one antireflection layer containing Sio2 and a material layer made of a composition produced by adding compound having small interaction with said SiO2 to compound having alkoxysilane group at terminal and perfluoroether group and which is expressed by the following formula 1 on said antireflection layer:
- RfCOR1—R2—Si(OR3)3
- (Rf represents perfluoropolyether group)
- R1 represents any one of O, NH, S
- R2 represents alkylene chain
- Rs represents alkyl group
