17 Claims

1. An anti-glare film comprising: a light-transmitting substrate; and a hard coating layer containing a binder resin and inorganic fine particles dispersed in the binder resin,

wherein a reflection intensity ratio (R) of Equation 1 is 0.6 to 1%, and

a ratio of an external haze to the reflection intensity ratio (R) of the anti-glare film is 10 to 30:

Reflection Intensity Ratio (R)=(R₁/R₂)×100 [Equation 1]

wherein, in the Equation 1,

R₁is a reflection intensity value measured at 45° corresponding to a specular reflection of the incident angle after irradiating light at an incident angle of 45° with respect to the hard coating layer, and

R₂is a reflection intensity value measured at 45° corresponding to a specular reflection of the incident angle after irradiating light at an incident angle of 45° with respect to the light-transmitting substrate.
