Description

The present invention relates to an anti-glare film provided on the surface of a high-definition image display such as a CRT and a liquid crystal panel used for image display of a computer, a word processor, a television, etc., a polarizing film using the anti-glare film, and a transmission type display device. .

In the display as described above, when light emitted mainly from the inside goes straight without diffusing on the display surface, when the display surface is visually observed, it is dazzling, and an anti-glare film for diffusing light emitted from the inside to some extent is provided. Provided on the display surface.

For example, as disclosed in JP-A-6-18706, JP-A-10-20103, etc., this antiglare film includes a resin containing a filler such as silicon dioxide (silica) on the surface of a transparent substrate film. It is formed by coating.

These anti-glare films are of a type in which irregularities are formed on the surface of the anti-glare layer by agglomeration of particles such as cohesive silica, and an organic filler having a particle size greater than the thickness of the coating film is added to the resin to form a layer. There is a type in which an uneven shape is formed on the surface, or a type in which a film having unevenness is laminated on the layer surface to transfer the uneven shape.

In the conventional antiglare film as described above, in any type, the light diffusion / antiglare action is obtained by the action of the surface shape of the antiglare layer. However, there is a problem in that, when the unevenness increases, the haze value (haze value) of the coating film increases, and the transmission sharpness decreases accordingly.

Similar to the above, a light diffusion film in which fine particles are dispersed inside a layer to obtain a light dispersion effect is used, for example, for a reflection type liquid crystal display device, Journal of the Illuminating Engineering Institute of Japan, MD-96-48 (1996). Pp. 277-282.

In order to obtain a sufficient light diffusion effect by the internal scattering effect used here, it is necessary to increase the particle size of the fine particles used. Therefore, although the haze value is high, the sharpness of the image is extremely low. Has the problem of being small.

Further, when a light-diffusing film, such as the light-diffusing film, which obtains a light-diffusing effect on the display surface is used for anti-glare use, the surface is almost flat, so that external light is reflected on the display surface. There is also a problem that the image cannot be prevented, and there is no so-called reflection prevention property.

Furthermore, the conventional type of antiglare film has a problem in that a so-called scintillation glittering is generated on the film surface, and the visibility of the display screen is reduced.

There is a haze value as one of the evaluation criteria of such an anti-glare film, but when the haze value of the surface is lowered, a sense of glare called so-called glare increases, and the haze value is increased in an attempt to eliminate this. Then, there is a problem that the whole becomes whitish and the black density is reduced, whereby the contrast is reduced. Conversely, if the haze value is reduced to remove whiteness, there is a problem that so-called reflection and glare are increased.

In order to solve the above-mentioned problems, the present inventors have improved the transmission clarity, reduced the scintillation, and have the anti-reflection property without reducing the diffusion and anti-glare properties. We have developed a glare film and filed an application as Japanese Patent Application No. 10-125494.

曇 In order to realize the above characteristics, it is necessary to adjust the haze value by the internal scattering effect. The internal scattering effect is based on the mixing ratio of the light-transmitting fine particles and the light-transmitting resin, the difference in the refractive index between the light-transmitting fine particles and the light-transmitting resin, the particle size of the light-transmitting fine particles, and the dry film thickness of the antiglare layer. It is possible by such control.

However, since the adjustment of the mixing ratio, the particle diameter, and the film thickness also affects the surface shape, it is not possible to adjust only the haze value while keeping the reflection preventing property and the transmission clearness constant. There are points.

内部 Although the internal scattering effect can be controlled by the refractive index of the light-transmitting fine particles, there is also a problem that the adjustment of the haze is restricted by the refractive index of the light-transmitting fine particles.

The present invention has been made in view of the above-described conventional problems, and, in the haze value within a desired range, without decreasing the reflection property, improving the transmission clearness, and reducing the scintillation. An object of the present invention is to provide an anti-glare film, a polarizing plate using the anti-glare film, and a transmissive display device.

The present invention is an anti-glare film formed by laminating at least a transparent base film and an anti-glare layer containing at least two or more types of light-transmitting fine particles in a light-transmitting resin. The difference in refractive index between the light-transmitting fine particles and the light-transmitting resin is 0.03 or more and 0.20 or less, and the two or more types of light-transmitting fine particles have a difference in refractive index. The above object is achieved by an antiglare film characterized by the above.

According to another aspect of the present invention, the difference between the refractive indices of the two or more types of light-transmitting fine particles may be 0.02 or more and 0.10 or less.

As in claim 3, the refractive index of the translucent resin is 1.49 to 1.53, and the refractive index of the translucent fine particles is 1.53 to 1.57 and 1.58 to 1 .62.

According to a fourth aspect of the present invention, the above object is achieved by an antiglare film having a haze value of 10% or more.

As in claim 5, the light-transmitting resin is an ionizing radiation-curable resin, the particle size of the two or more types of light-transmitting fine particles is 1 to 5 μm, and the two or more types of light-transmitting particles are different. The content of the fine particles in the antiglare layer may be 5 to 30% by weight.
Further, the translucent fine particles may be monodisperse organic fine particles.
Furthermore, the light-transmitting fine particles may be inorganic fine particles.
Further, the transparent substrate film may be a triacetyl cellulose film.

The invention according to the polarizing plate is, as described in claim 9, a polarizing element, and the above-described anti-glare layer laminated on the surface of the polarizing element with the surface on the side opposite to the anti-glare layer of the transparent substrate film facing. The above-mentioned object is achieved by comprising a glare film.

Further, according to the invention of a transmissive display device, as in claim 10, a planar translucent display body, a light source device for irradiating the translucent display body from behind, and a surface of the translucent display body And an anti-glare film as described above laminated on a transparent display device to achieve the above object.

Since the present invention is configured as described above, an anti-glare method capable of improving transmission clarity and reducing scintillation without lowering reflection properties at a haze within a desired range. A film can be easily obtained.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the anti-glare film 10 according to the embodiment of the present invention includes, for example, a first light-transmitting fine particle 16 and a second light-transmitting fine particle 16 in a light-transmitting resin 14. And the anti-glare layer 18 including the light-transmitting fine particles 46. Here, two types of light-transmitting fine particles having different refractive indices will be described, but two or more types of light-transmitting fine particles may be used.

The transparent substrate film 12 is a resin film such as a triacetyl cellulose film, and the translucent resin 14 can be cured after being applied to the transparent substrate film 12, and may be, for example, an ultraviolet-curable resin (having a refractive index of 1. 51), the first light-transmitting fine particles 16 are made of a light-transmitting resin, for example, acryl-styrene copolymer beads (refractive index 1.55), and the second light-transmitting fine particles 46 are formed. Is made of a translucent resin, for example, styrene beads (refractive index: 1.60).

The difference between the refractive indices of the light-transmitting fine particles 16 and 46 and the light-transmitting resin 14 is set to 0.02 or more and 0.20 or less from the viewpoint of the antiglare property. When the refractive index difference is less than 0.22, the difference in refractive index between the two is too small to obtain the light diffusing effect. Is whitened. The difference in refractive index is more preferably 0.02 or more and 0.11 or less, and most preferably 0.03 or more and 0.09 or less.

In the light-transmitting fine particles, two or more kinds of light-transmitting fine particles having different refractive indices are used, and by mixing these light-transmitting fine particles, the refractive index of the light-transmitting fine particles is changed to the refractive index of the light-transmitting fine particles. The ratio can be regarded as an average value according to the ratio, the finer refractive index can be set by the mixing ratio of the light-transmitting fine particles, the control can be performed more than one type, and various designs can be facilitated.

Among the light-transmitting fine particles, the difference between the refractive indices of the first light-transmitting fine particles 16 and the second light-transmitting fine particles 46 was set to 0.02 or more and 0.10 or less because the difference in the refractive index was large. If it is less than 0.02, the difference between the two refractive indices is too small to control the refractive index even if the two are mixed. When the refractive index is large, the light diffusing property is determined by the translucent fine particles having a large refractive index. The refractive index difference is more preferably 0.02 or more and 0.08 or less, and most preferably 0.03 or more and 0.07 or less.

The particle diameter of the light-transmitting fine particles 16 and 46 is preferably 1.0 μm or more and 5.0 μm or less, and if it is less than 1.0 μm, the amount of the light-transmitting fine particles to be added to the light-transmitting resin 14 is very small. If the diameter is not increased, the light diffusion effect cannot be obtained, and if the particle diameter exceeds 5.0 μm, the surface shape of the antiglare layer 18 becomes coarse and the haze value increases. More preferably, the diameter of the translucent fine particles is 2 μm or more and 4 μm or less.

The translucent fine particles 16 and 46 may be monodisperse organic fine particles or inorganic fine particles. The smaller the variation in particle size, the smaller the variation in scattering characteristics, and the easier the design of haze value.

As described above, a state in which high transmissivity is maintained without whitening the entire film due to a slight difference in refractive index between the translucent fine particles 16 and 46 as the filler and the translucent resin 14. Thus, the light transmitted through the antiglare film 10 can be averaged by the diffusion effect.

素材 As a material of the transparent substrate film 12, there are a transparent resin film, a transparent resin plate, a transparent resin sheet and a transparent glass.

Films, polycarbonate films, polysulfone films, polyether films, polymethylpentene films, polyetherketone films, (meth) acrylonitrile films and the like can be used. The thickness is usually about 25 μm to 1000 μm.

As the transparent base film 12, a TAC film having no birefringence can be used to produce a polarizing plate by laminating an anti-glare film with a polarizing element (described later). This is particularly preferable because a liquid crystal display device excellent in the above can be obtained.

In addition, PET is particularly desirable as the transparent substrate film 12 from the viewpoints of workability such as heat resistance, solvent resistance and mechanical strength when the antiglare layer 18 is applied by various coating methods.

As the translucent resin 14 forming the anti-glare layer 18, a resin mainly cured by ultraviolet rays and electron beams, that is, an ionizing radiation curable resin, a mixture of a thermoplastic resin and a solvent in an ionizing radiation curable resin, Three types of thermosetting resins are used. The thickness is usually about 0.5 μm to 50 μm, preferably 1 μm to 20 μm, and more preferably 2 μm to 10 μm.

It is composed of an ionizing radiation curable resin containing a relatively large amount of a prepolymer and a reactive diluent. Examples of the diluent include monofunctional monomers such as ethyl (meth) acrylate, ethylhexyl (meth) acrylate, styrene, vinyltoluene, and N-vinylpyrrolidone, and polyfunctional monomers such as trimethylolpropane tri (meth) acrylate and hexanediol.

Further, when the above ionizing radiation-curable resin is used as an ultraviolet-curable resin, acetophenones, benzophenones, Michler benzoyl benzoate, α-amyloxime esters, thioxanthones and the like are used as photopolymerization initiators in these resins. And n-butylamine, triethylamine, tri-n-butylphosphine and the like as a photosensitizer. In particular, in the present invention, it is preferable to mix urethane acrylate as an oligomer and dipentaerythritol hexa (meth) acrylate as a monomer.

Further, as the light-transmitting resin 14 for forming the antiglare layer 18, a solvent-drying resin may be contained in the ionizing radiation-curable resin as described above. The solvent-drying type resins mainly include thermoplastic resins such as senol resin, urea resin, diallyl phthalate resin, melamine resin, guanamine resin, unsaturated polyester resin, polyurethane resin, epoxy resin, amino alkyd resin, and melamine-urea resin. Condensed resins, silicon resins, polysiloxane resins and the like are used.

As the type of the solvent-drying type thermoplastic resin to be added to the ionizing radiation-curable resin, a commonly used type is used. However, when a cellulose-based resin such as TAC as described above is used as the transparent base film 12, particularly, As the solvent-drying resin contained in the curable resin, cellulose resins such as nitrocellulose, acetylcellulose, cellulose acetate propionate, and ethylhydroxyethylcellulose are advantageous in terms of adhesion and transparency of the coating film.

The curing method of the ionizing radiation-curable resin composition described above can be a usual curing method of the ionizing radiation-curable resin composition, that is, the resin composition can be cured by irradiation with an electron beam or ultraviolet rays.

For example, in the case of electron beam curing, 50 to 1000 KeV emitted from various electron beam accelerators such as Cockrow-Walton type, Bande graph type, Resonant transformation type, Insulating core transformer type, Linear type, Dynamitron type and High frequency type. Preferably, an electron beam or the like having an energy of 100 to 300 KeV is used. In the case of ultraviolet curing, an ultraviolet ray emitted from a light beam such as an ultra-high pressure mercury lamp, a high pressure mercury lamp, a low pressure mercury lamp, a carbon arc, a xenon arc, and a metal halide lamp is used. it can.

As the first light-transmitting fine particles 16 contained in the anti-glare layer 18, plastic beads are preferable, and the first light-transmitting fine particles 16 are particularly high in transparency, and have a refractive index difference from the light-transmitting resin 14 as described above. Is preferred.

Acrylic-styrene copolymer beads (refractive index: 1.55), melamine beads (refractive index: 1.57), polycarbonate beads (refractive index: 1.57) are used as the plastic beads used for the first translucent fine particles 16. , Etc. are used.

The second translucent fine particles 46 contained in the anti-glare layer 18 are preferably plastic beads, particularly those having high transparency and having a refractive index difference from the translucent resin 14 as described above. Is preferred.

ス チ レ ン As the plastic beads used for the second translucent fine particles 46, styrene beads (refractive index: 1.60), polyvinyl chloride beads (refractive index: 1.60), and the like are used.

The particle diameter of the plastic beads of the first light-transmitting fine particles 16 and the second light-transmitting fine particles 46 may be appropriately selected from those of 1 to 5 μm as described above, and may be 100 parts by weight of the light-transmitting resin. And 5 to 30 parts by weight with respect to the weight. In this case, by making the particle diameters of the first light-transmitting fine particles 16 and the second light-transmitting fine particles 46 uniform, the ratio of the first light-transmitting fine particles 16 to the second light-transmitting fine particles 46 can be freely set. Can be selected and used. In order to make the particle diameters of the first light-transmitting fine particles 16 and the second light-transmitting fine particles 46 uniform, monodisperse organic fine particles having a uniform particle diameter are preferably used.

When the first light-transmitting fine particles 16 and the second light-transmitting fine particles 46 as described above are added, the light-transmitting fine particles easily settle in the resin composition (light-transmitting resin 14). An inorganic filler such as silica may be added to prevent sedimentation. In addition, as the amount of the inorganic filler increases, it is more effective in preventing sedimentation of the light-transmitting fine particles, but has an adverse effect on the transparency of the coating film. Therefore, it is preferable that the inorganic filler having a particle size of 0.5 μm or less be contained in the translucent resin 14 in an amount of less than 0.1% by weight so as not to impair the transparency of the coating film.

Next, a process of forming the antiglare layer 18 on the surface of the transparent base film 12 will be described.

The transparent base film 12 is coated with a light-transmitting resin 14 in which the first light-transmitting fine particles 16 and the second light-transmitting fine particles 46 are mixed, and the first light-transmitting fine particles 16 are mixed. And the second light-transmitting fine particles 46 are allowed to stand until the irregularities on the surface of the light-transmitting resin are sufficiently formed. Then, when the light-transmitting 14 is an electron beam or an ultraviolet curable resin, these electron beams are used. Alternatively, it is cured by irradiation with ultraviolet rays.

By doing so, the anti-glare layer 18 becomes a smooth state as a whole, and the anti-glare layer 18 in which the first light-transmitting fine particles 16 and the second light-transmitting fine particles 46 have unevenness can be formed. . Here, an example in which the irregularities are formed is shown, but an antiglare layer in which the irregularities are not formed may be used.
Further, the surface of the anti-glare layer 18 may be subjected to shaping or mirror finishing.

The anti-glare film 11 has a configuration in which an anti-glare layer 18 is laminated on a TAC film 12A.

ＴＡ Since TAC, which is provided on both outer sides of the polarizing layer 22 and serves as a transparent base material, has no birefringence and does not disturb the polarization, the polarization is not disturbed even when laminated with PVA and PVA + iodine film serving as the polarizing element. Therefore, a liquid crystal display device having excellent display quality can be obtained by using such a polarizing plate 20.
