Abstract
A light-absorptive antireflection film comprising a light-absorptive film formed on a glass substrate containing pigment microparticles and having a physical thickness of not less than 10 nm and an antireflection multilayer film attenuating reflected light of incident light by interference of light, wherein at least one layer of the antireflection multilayer film is an electroconductive thin film having a surface resistance of not more than 1000 Ω/□, and a display device including the same and methods of producing them.
Claims27
A light-absorptive antireflection filter that allows incident light incident on a first surface side to pass at a predetermined transmittance and that attenuates reflected light of the incident light reflected from a second surface side by interference of light at an antireflection multilayer film, said light-absorptive antireflection filter comprising:
- a light-absorptive film formed on the first surface side and containing pigment microparticles;
- the antireflection multilayer film formed on the second surface side and contacting the light-absorptive film;
- and
- at least one electroconductive thin film included in the antireflection multilayer film.
A display device comprising:
- a display unit displaying an images;
- and
- a light-absorptive antireflection multilayer film formed on the display unit, the light-absorptive antireflection multilayer film allowing light incident on a first surface side of the display unit side to pass at a predetermined transmittance, and attenuating reflected light of the incident light reflected from a second surface side said light-absorptive antireflection multilayer film comprising:
- a light-absorptive film formed on the first surface side and containing pigment microparticles,
- an antireflection multilayer film formed on the second surface side and contacting the light-absorptive film, and
- at least one electroconductive thin film included in the antireflection multilayer film.
