Abstract

[Summary] The present invention relates to an anti-glare film and a display apparatus, and more particularly to an anti-glare film including: a light-transmitting substrate; and a hard coating layer containing a binder resin, organic fine particles and inorganic fine particles dispersed in the binder resin, wherein a ratio of two or more organic fine particles aggregating with each other in the whole organic fine particles is 5% or less, and wherein a ratio of internal haze to external haze is 2.5 or less, and a display apparatus including the anti-glare film.

Claims (19)

1 . An anti-glare film comprising: a light-transmitting substrate; and

a hard coating layer containing a binder resin, organic fine particles and inorganic fine particles,

wherein the organic fine particles and the inorganic fine particles are dispersed in the binder resin,

wherein the hard coating layer has a thickness of 1 to 10 μm,

wherein the organic fine particles have a diameter of 0.5 μm to 6 μm and a refractive index of 1.500 to 1.600 at a wavelength of 550 nm,

wherein the inorganic fine particles have a diameter of 0.01 μm to 5 μm,

wherein a ratio of two or more organic fine particles aggregating with each other in the total organic fine particles is 2.0% to 4.08%, and

wherein the anti-glare film has an external haze value of 9.2 to 9.8%, an internal haze value of 11.5 to 13.6%, and a ratio of internal haze to external haze of 1.3 to 1.5.

wherein two adjacent organic fine particles among the two or more organic fine particles aggregating with each other are located at different distances from one surface of the hard coating layer,

and the ratio of the two or more organic fine particles existing while aggregating, in the total organic fine particles, at different positions in the thickness direction of the hard coating layer in this way is adjusted to 3.5% or less and,

wherein two adjacent organic fine particles among the two or more organic fine particles aggregating with each other have a focus on respective optical microscopes at different positions with respect to a thickness direction on the basis of one surface of the hard coating laye

wherein two adjacent organic fine particles among the two or more organic fine particles aggregating with each other are located with a distance difference of at least 0.1 μm from one surface of the hard coating layer.

2 . The anti-glare film according to claim 1 , wherein two adjacent organic fine particles among the two or more organic fine particles aggregating with each other have a focus on respective optical microscopes at different positions with respect to a thickness direction on the basis of one surface of the hard coating layer.

3 . The anti-glare film according to claim 1 , wherein the binder resin includes a polymer or copolymer of a vinyl-based monomer or a (meth)acrylate-based monomer.

4 . The anti-glare film according to claim 1 , wherein the hard coating layer contains 5 to 25 parts by weight of the organic fine particles based on 100 parts by weight of the binder resin.

5 . The anti-glare film according to claim 1 , wherein the light-transmitting substrate has a thickness direction retardation (Rth) of at least 3,000 nm as measured at a wavelength of 400 nm to 800 nm.

6 . A display apparatus comprising the anti-glare film according to claim 1 .

7 . The display apparatus according to claim 6 , wherein the display apparatus is a notebook display device, and the anti-glare film is located on an outermost surface of the notebook display device.

8 . The anti-glare film according to claim 1 , wherein two adjacent organic fine particles among the two or more organic fine particles aggregating with each other are located with a distance difference of at least 0.1 μm from one surface of the hard coating layer.
