15 Claims

1. An anti-glare film comprising:

a laminate comprising a light transmitting substrate, and a hard coating layer comprising a binder resin, and inorganic particles and organic particles dispersed in the binder resin,

wherein a difference (Ha−Hi) between a total haze (Ha) and an internal haze (Hi) of the laminate is 5 to 15%, and

in the infrared (IR) spectrum of the laminate, a rate (I B/I A) of the peak area (I B) existing between 1500 cm-1 to 1570 cm-1, to the peak area (I A) existing between 1690 cm-1 to 1745 cm-1 is 0.1 to 0.6, and

a transmission diffusion distribution of the laminate according to the following Formula 1 is greater than 1% and less than 10%:

Transmission diffusion distribution=(B/A)×100 [Formula 1]

wherein A is transmission intensity of light transmitted in the normal direction of the hard coating layer, after irradiating light in the normal direction of the light transmitting substrate, and

B is transmission diffusion intensity of light transmitted at +1° or −1° based on the normal direction of the hard coating layer, after irradiating light in the normal direction of the light transmitting substrate.
