Abstract
An anti-reflection film comprises a low refractive index layer provided on one surface of a transparent support. The low refractive index layer has a refractive index of not higher than 1.45. The low refractive index layer has a surface average reflectance of not higher than 1% within the visible region of 400 to 800 nm. According to the first embodiment of the present invention, an infrared absorbing layer is provided between the transparent support and the low refractive index layer. According to the second embodiment of the present invention, an infrared absorbing layer is provided on the other surface of the transparent support. The infrared absorbing layer contains an infrared absorbing dye. The infrared absorbing layer decreases a transmittance of the film to not higher than 40% at a wavelength within the infrared region of 800 to 1,100 nm. Plasma display panels using the anti-reflection films are also disclosed.
