Abstract
The present invention provides an anti-reflection film which allows more appropriate black indication by reason of selectively restraining tinging with blue on the occasion of being provided for a transmission liquid crystal display surface to offer a black indication by changing the optical properties of the anti-reflection film. The anti-reflection film provided with visibility-average light transmittance absorption loss is within a range of 0.5% or more and 3.0% or less, a value obtained by subtracting a minimum value of light transmittance absorption loss at each wavelength in a visible light region from the maximum value thereof is within a range of 0.5% or more and 4.0% or less, and light transmittance absorption loss at each wavelength satisfies Q>Q>Q(Q, Qand Q: light transmittance absorption loss at a wavelength of 450 nm, 550 nm and 650 nm).
