Abstract

See full text

An anti-glare film comprises an anti-glare layer, and a low-refraction-index layer formed on at least one surface thereof and comprising a low-refraction-index resin and a hollow silica particle. The film has an internal haze of 0 to 1%, a haze of 5 to 6.5%, a transmitted image clarity of 20 to 30%, and a reflected light of the film has a* of 0.5 to 1.3 and b* of -2.3 to -0.5. The particle may have a mean particle diameter of about 50 to 70 nm and a refraction index of about 1.2 to 1.25. The film may have an uneven surface, and the average inclination angle of the surface may be about 0.7 to 1.degree.. The anti-glare layer may comprise plural polymers and have a domain formed by a phase separation, and a difference in refraction index between the polymers may be about 0 to 0.04.
