Problems solved by technology

[0010] However, in the case of the anti-glare film, it is possible to scatter reflected light isotropically, and lower the contrast ratio according to the scattered reflected light
In this method, it is not easy to control the phase separation, and as long as the raw material group and polymer components change, the size of the phase separation structure will change greatly, so it is not easy to realize the stable preparation of the anti-glare film

[0128] [Preparation method of anti-glare film]

[0129] The anti-glare film of the present invention is prepared by the following steps: the wet coating film is inclined relative to the horizontal plane, and at the same time, the wet coating film is dried, and the wet coating film (undried) is subjected to honeycomb rotational convection in the above steps, wherein, The wet coating is formed from a solution comprising at least one polymer, at least one curable resin precursor and a solvent. More specifically, it is generally carried out by applying the solution on a substrate and tilting the resulting wet coating film while evaporating the solvent from the coating film. A more preferable preparation method may be that a solution containing a plurality of polymers capable of phase separation, at least one curable resin precursor, and a solvent having a boiling point above 100° C. is coated on a substrate, and the formed wet coating The film is placed at an inclination with res...

Abstract

This invention provides an anti-dazzling film comprising an anti-dazzling layer. The anti-dazzling layer comprises a matrix of a polymer and a plurality of domains of a polymer which are in phase separation from the matrix. The domains and the matrix are formed in a concave-convex form on the surface of the anti-dazzling layer. The sharpness of image measured with an image clarity measuring device using an optical comb is different in film installation direction to the optical comb. For this film, in the image sharpness measured with the image clarity measuring device using a 0.5 mm-width optical comb, the difference (absolute value) between the image sharpness for the film installed in such a direction that the film formation direction is parallel to the comb tooth direction of the optical comb, and the image sharpness for the film installed in such a direction that the film formation direction is vertical to the comb tooth direction of the optical comb, may be about 1 to 30. This anti-dazzling film can display a sharp image in which external light reflection and dazzling could have been suppressed.

Description

technical field [0001] The present invention relates to a kind of anti-glare film, and this anti-glare film is used on various display (liquid crystal display) such as computer, word processor, television, the present invention also relates to the preparation method of anti-glare film and the display device. Background technique [0002] In recent years, various displays have been developed, including liquid crystal displays, plasma displays, organic EL displays, inorganic EL displays, field emission displays FED, and the like. In particular, the use of liquid crystal displays as display devices used for television (TV) applications and animation display applications has brought remarkable progress and has rapidly spread.
