Abstract:
An anti-reflection film enabling adjustment of light transmittance in a wide range and a display device having a desirable display quality is achieved by forming an anti-reflection film on the surface of a panel base for displaying an image. The anti-reflection film includes first and second optical absorption films, each of which is composed of at least one kind selected from a group consisting of a metal film, a metal nitride film and a metal oxide film, and a dielectric film having a refractive index ranging from about 1.4 to about 1.9, which is formed between the first and second optical absorption films. For example, the following three films are sequentially formed on a panel glass for a Braun tube: a first optical absorption film of TiN having a thickness of 10 nm; a dielectric film of Al 2 O 3, having a thickness of 82 nm; and a second optical absorption film of TiN having a thickness of 12 nm, to thus form an anti-reflection film.

Abstract:
PROBLEM TO BE SOLVED: To provide an anti-fouling hard coat made by laminating an adhesive layer and an anti-fouling layer in order on a hard coat, and having a superior transparency and protecting from occurrence of a coating uneveness on the anti-fouling layer. SOLUTION: The adhesive layer 13 comprising a silane coupling agent is formed on the hard coat 12 and further the anti-fouling layer 14 comprising a perfluoropolyether having a polar group at the both molecular ends and containing a catalyst containing one or at least two of a catalyst selected from a group consisting of an acid, a base, a phosphate ester and β-diketone is formed on the adhesive layer 13. Thereby, in a case that the anti-fouling layer 14 is formed on the adhesive layer 13, the coating unevenness can be prevented from occurring on the anti-fouling layer 14 can be prevented.

PROBLEM TO BE SOLVED: To provide an optical filter excellent in reflecting characteristics and capable of adjusting transmittance in a wide range. SOLUTION: A two-layer antireflection film 3 comprising a light absorbing film 3a and a transparent dielectric film 3b is disposed on one face of a transparent substrate 2 and a colored adhesive layer 4 which transmits more light in a specified light-emitting area than light in another light-emitting are is disposed on the other face of the substrate 2.
Abstract:
PROBLEM TO BE SOLVED: To stick a functional film to a large display device having a large adhesive area with simple equipment with taking in of dust reduced as much as possible by conducting electrostatic air blowing to the panel surface immediately before press-sticking is performed, then successively press-sticking a functional film to the panel surface where the electrostatic air blowing is conducted. SOLUTION: One end of an adhesive layer 15 of a functional film 10 is brought into contact with one end of a panel surface 3 for alignment and the one end of the functional film 10 is press stuck to the panel surface 3 with a roller 4. Electrostatic air blowing is conducted to the press-sticking part of a non-sticking part 10b of the functional film 10 and the panel surface 3 with an electrostatic air gun 5, and at the same time the roller 4 is advanced toward the other end of the panel surface 3, and the functional film 10 is press- stuck to the panel surface 3. Static electricity on the panel surface 3 and the adhesive layer 15 is removed, and dust attached there is blown out at the same time. A clean room with a high level is made unnecessary and production equipment is made simple.
