Problems solved by technology

However, when the surface of the image display device is not only configured with an anti-glare film that does not reflect much, but also has an anti-glare film that has anti-glare properties to the extent that the reflection is not annoying, the screen image light will be absorbed by the anti-glare layer. Scattering occurs due to the uneven surface, which may cause so-called glare
In order to prevent the occurrence of glare, some people proposed to increase the haze. When the haze is increased, the glare can be prevented, but the contrast may be reduced.

[0045] Hereinafter, an antiglare film and the like according to a first embodiment of the present invention will be described with reference to the drawings. First of all, in this specification, terms such as "film", "sheet", and "plate" cannot be distinguished from each other only based on the difference in names. Therefore, for example, a "film" is a concept that also includes a member that can also be called a sheet or a plate. As a specific example, the "anti-glare film" also includes members called "anti-glare sheet" or "anti-glare plate". In addition, in this specification, a "weight average molecular weight" is the value obtained by dissolving in solvents, such as tetrahydrofuran (THF), and carrying out polystyrene conversion by the conventionally well-known gel permeation chromatography (GPC) method.

Abstract

The invention is to provide an antiglare film, a polarizing plate, a liquid crystal panel and an image display device, in which antiglare property can be obtained to such a degree that reflection barely causes troubles, and good antidazzle property and good black color feeling can be obtained. According to an embodiment of this invention, the anti-glare film (10) is provided that includes a translucent substrate (11) and an anti-glare layer (12) installed on the translucent substrate (11). The surface of the anti-glare layer (12) is a concave / convex surface (12A). The anti-glare layer (12) includes an adhesive resin (16) and a plurality of first inorganic fine particle aggregates (13) that exist in the adhesive resin (16) and have at least 3 inorganic fine particles for aggregation. The first inorganic fine particle aggregates (13) include a bent portion (13A) that uses the inorganic fine particles as connecting means to form and include an inner region (13B) that has an embedded adhesive resin (16).

Description

[0001] This application is a divisional application, and the Chinese national application number of the application it targets is 201410379744.9, the filing date is August 4, 2014, and the invention name is "anti-glare film, polarizer, liquid crystal panel and image display device". 【Technical field】 [0002] The invention relates to an anti-glare film, a polarizer, a liquid crystal panel and an image display device. 【Background technique】 [0003] On the image display surface of image display devices such as liquid crystal display (LCD), cathode line tube display (CRT), plasma display (PDP), electroluminescence display (ELD), field emission display (FED), etc., Generally, in order to suppress the reflection of the observer and the background of the observer, etc., an anti-glare film with unevenness on the surface, or an anti-reflection film with an anti-reflection layer on the outermost surface (for example, refer to Japanese Patent Laid-Open No. 2011-215515 Bulletin).
