20080206458METHOD FOR PRODUCING ANTI-GLARE FILM - A method for producing an anti-glare film includes applying a coating composition including at least a resin, a solvent, and fine particles to a substrate; drying the coating composition applied to the substrate so that a Benard cell structure is formed in the surface of the coating layer due to convection caused during volatilization of the solvent; and curing the resin contained in the coating composition having formed therein a Benard cell structure to form an anti-glare layer having fine irregularities with a moderate surface waviness. The anti-glare layer has a degree of white muddiness of 1.7 or less, as measured by quantitatively determining a diffuse reflection component of the diffused light incident upon the surface of the anti-glare layer.08-28-2008

20090015927ANTIGLARE FILM, METHOD FOR MANUFACTURING ANTIGLARE FILM, POLARIZER, AND DISPLAY DEVICE - An antiglare film includes a base material and an antiglare layer which is disposed on at least one surface of the base material and which contains fine particles and a resin, wherein the fine particles constitute aggregates mainly in in-plane directions, and gradual unevenness is disposed on the surface of the antiglare layer through aggregation of the fine particles.01-15-2009
20090290220ANTI-GLARE FILM, METHOD FOR MANUFACTURING, THE SAME, AND DISPLAY DEVICE USING THE SAME - An anti-glare film has a plurality of diffuser elements, and has specified optical properties. The ratio of I(α+1)/I(α) is more than 0.1 to 0.6, where I(α) is an intensity of a light reflected toward an arbitrary angle α of 10° or less from a specular reflection direction of an incident light upon the surface at an angle of 5° to 30° from the surface normal, and I(α+1) is an intensity of a reflected light deviated from the arbitrary angle α by 1° in a wide-angle direction. The gain of a light reflected in the direction at 20° or more from the specular reflection direction of the incident light is 0.02 or less, in which the gain is obtained by normalizing a reflected light intensity using a specular reflection intensity of a standard diffuse plate as 1. The diffuser elements have an average space therebetween of 50 to 300 micrometers.11-26-2009
