Abstract

An anti-glare film has a plurality of diffuser elements, and has specified optical properties. The ratio of I (α +l)/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 DEG or less from a specular reflection direction of an incident light upon the surface at an angle of 5 DEG to 30 DEG from the surface normal, and I (α +l) is an intensity of a reflected light deviated from the arbitrary angle α by 1 DEG in a wide-angle direction. The gain of a light reflected in the direction at 20 DEG 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.

Description

201003130 VI. Description of the Invention: [Technical Field] The present invention relates to an anti-glare film, a method for producing an anti-glare film, and a display device using an anti-glare film. In particular, the present invention relates to an anti-glare film for use on a surface of a display device such as a liquid crystal display, an electroluminescent display, or a cathode ray tube (CRT) display, and a method of manufacturing an anti-glare film And a display device using an anti-glare film. This application claims the Japanese Patent Application No. 2007-033855 filed on February 14, 2007, and the Japanese Patent Application No. 2 filed on Dec. 28, 2007. Priority rights to 7-34122, the entire contents of which are incorporated herein by reference. [Prior Art] In a display device such as a liquid crystal display, a plasma display, and a CRT display, visibility is significantly deteriorated when ambient light from fluorescent illumination or the like is reflected in the surface of the display device. Therefore, a method of forming an optical multilayer film or a low refractive index film on the surface of a display device to reduce the reflectance of the surface or an anti-glare film having a very uneven surface on the surface of the display device has been employed to cause an environment A method of diffusing reflection of light to blur the reflected image. However, the use of optical multilayer films increases production costs and does not achieve satisfactory anti-glare properties. By suppressing an increase in production cost by using a low refractive index film, the resulting surface has a relatively high reflectance, and thus a problem of disturbing reflection in the surface occurs. On the other hand, in the incorporation of a mixture of vermiculite filler, 142498.doc 201003130 organic filler or similar filler to form a surface with fine irregularities and use diffuse reflection to blur the reflection in the surface of the display. 'The anti-glare property is obtained; however, the appearance of self-coloring and staining is strong, and the contrast is reduced especially when the light intensity is j, so the visibility is deteriorated. In recent years, there has been a need for a surface treatment which suppresses the appearance of white turbidity and which increases the contrast while suppressing the appearance of white turbidity, and has developed some methods for the treatment. For example, in Japanese Unexamined Patent Publication No. 02 365410 (hereinafter referred to as "Patent Document No."), a method for obtaining an anti-glare film which is impossible to whitish while preventing reflection in a surface is disclosed. One is offset from the specular reflection direction by 2 〇. The intensity of the reflected light is one to the normal to the surface of the anti-glare film. The ratio of the specular reflection intensity of the incident light in the direction is 〇 2 or less and the half bandwidth 7 of the peak of the reflected light intensity. Or bigger. In the unexamined Patent Application Publication No. 2004-61 853 (hereinafter referred to as "Patent Document 2"), an anti-glare film is disclosed which is formed at a ratio of 5 to the normal to the surface of the anti-glare film. The specular reflectance of the collimated incident light at an angle is substantially equal to the deviation from the specular surface by 〇·2. The reflection ratio of the specular reflection direction of the incident light at an angle. Further, Patent Document 2 discloses a method for obtaining an anti-glare film having a value of 1/1, 〇〇〇 or less, in which the same measurement is performed. This value is obtained by normalizing the intensity of the reflected light toward the direction perpendicular to the light incident on the anti-glare film at an angle of 20 or more using a standard diffuser plate (hereinafter, the reflected light from the standard diffuser plate will be used) The intensity of the reflected light whose intensity is normalized is called "gain,·). 142498.doc 201003130 Unexamined Patent Application Publication Nos. 2006-53371 and 2004-2404 1 1 (hereinafter referred to as "Patent Document 3 " and, Patent Document 4, respectively. A method of glare film, wherein a regular reflectance of light incident on the anti-glare film at an incident angle of 5 to 3 Å is 1% or less, and is 3 Å or more with respect to the specular reflection direction. The ratio of the reflection ratio to the specular reflection ratio is 〇〇〇丨 or less. SUMMARY OF THE INVENTION However, there is a trade-off between the anti-glare property and the suppression of the appearance of white stain, and it is difficult to design an anti-glare film having two characteristics. And the solution is not good enough. For example, it has been found that a well-known anti-glare film having an irregular surface formed using a vermiculite filler satisfies the diffuse reflection characteristics specified in Patent Document 1 and the anti-glare film exhibits strong The appearance of white stain (the intensity ratio is 0.1 or less)' and the anti-glare film can achieve anti-glare characteristics while the half bandwidth is 7. or less. The fault is caused by a surface state with near mirror reflection. The film satisfies the diffuse reflection characteristic described in Patent Document 2 (where the specular reflectance is substantially equal to the reflectance of the specular direction of the incident light which is deviated from the specular reflection by 自2), and therefore only by The technique described in Patent Document 2 is difficult to obtain anti-glare H. Another method has been found by the inventors to find that even if the gain in the normal direction is about 1/100, the film is white, 蜀The appearance can also be satisfactorily lowered (although it is difficult to actually prepare an anti-glare film having a feature such that the gain in the normal direction is 1 Λ, 000 or less). Regarding the diffuse reflection characteristics specified in Patent Documents 3 and 4, It has been found that the presence of ρ causes the b glare film to have a relatively flat surface with large reflections, and the glare film 142498.doc 201003130 achieves a regular reflectance of 1% or less. Furthermore, it has been found to be subjected to low reflection processing (for example, formed on The anti-glare film of the low refractive index layer on the surface satisfies such diffuse reflection characteristics, but the anti-glare property is not good enough. Further, as described above, one has fine irregularities in the surface.

In the case of money, the same reference numerals are used in all figures to refer to parts or parts. 1 (1) First embodiment (1-1) configuration of anti-glare film FIG. 1 is an enlarged cross-sectional view of a full-scale port, which is not according to one of the first embodiment of the present invention. An example of the configuration of an anti-glare film. A plurality of protrusions are formed on the surface of the anti-glare film i as diffuser elements so that the surfaces have fine irregularities in common. The present inventors have conducted extensive and intensive studies on the diffuse reflection characteristics of the anti-glare film i. Therefore, it has been found that the anti-glare film 1 having the following specific diffuse reflection characteristics can be carefully observed: the eye hkh 1 , the 々 元 腰 Ί 极 极 极 极 极 极 极 极 极 极 极 极 极 极 极 极 极 极 极 极 极 极 极 极Anti-glare film. In order to prevent the glare property, it is necessary to reduce the absolute value of the specular reflection intensity, but it is more desirable that the diffuse reflection characteristic does not change abruptly. There is a correlation between the visual sensitivity of the human and the logarithm of the intensity of the light. Therefore, when the logarithm of the intensity of the diffuse reflection characteristic changes abruptly, the reflected edge of the light source is visually perceived, and thus the surface does not exhibit anti-glare characteristics. Therefore, the anti-glare film according to a first specific embodiment! A ratio greater than 〇 ilO SiKa+D/Ka is satisfied, wherein 1(a) is from a specular reflection direction of one incident light toward one turn.

If I(〇t+l)/I(a) When the ratio is not less than 〇1, the intensity changes rapidly and the edge tends to be 142498.doc •14- 201003130 Observed, so the anti-glare property is not perceived. If the ratio of Ra+丨)/〗 is greater than 0.6, the anti-glare is obtained. The characteristic, but the appearance of white staining becomes relative to the angle 5 from the normal to the surface 14. To 3 〇. The light incident in the direction becomes a full width of the angle of 1/1 〇〇 of the reflected light intensity which is one of the peaks of the reflected light intensity. To 28.0. Therefore, anti-glare characteristics similar to those of the diffuse reflection characteristics specified above are achieved. If the angle is full

The width is not more than 6.0. , the intensity changes rapidly and the edges tend to be observed. If the full width of the angle exceeds 28.0, the appearance of white turbidity is exhibited despite the anti-glare property. Likewise, an angle 5 is made relative to the normal direction relative to the surface 14. To 3 〇. The direction of the X# is changed to the full width of the w'ooo reflected light intensity which is one of the peaks of the reflected light intensity.

'The intensity changes rapidly and the edge leans toward observation. The full width of the right angle exceeds 45 〇. , although it achieves anti-glare properties, it exhibits the appearance of white turbidity. The diffuse reflection test with the optical film 1 is determined by using, for example, OPTEC c〇, the angular illuminance rGp^ paste reflected light intensity manufactured and sold by Ud. In phase 1 f, in order to remove the effect of reflection from the back surface, essentially the diffuse reflection characteristic of the anti-glare film, a black glass or enamel is passed through a binder; The board is bonded to the reverse side of the surface 14 of the anti-glare film 1. On the other hand, the appearance of white stain is 10 in the mirror direction. Or 142498.doc -15- 201003130 The angle of reflection from a larger angle is important. The reason for this is to reduce white turbidity by reducing the amount of light diffused in the wide-angle direction from the specular reflection direction.

The light incident on the surface in the direction of the angle is 2 与 to the specular reflection direction of the incident light. The gain of the light reflected by the larger or larger direction is a diffuse reflection characteristic of 〇〇2 or less, and the specular reflection intensity of the standard diffusion plate is used as the normalization one. This gain is obtained by reflecting the light intensity. Preferably, the gain of light reflected from the direction of specular reflection toward 20 or more is 〇 〇 or less. The light reflected in the direction of the larger or larger direction may have a gain of 0 25 or less, more preferably 〇.08 or less. The appearance of white turbidity in the anti-glare film can be suppressed by & Gain means a reflected light intensity normalized using a standard diffuser plate, and the gain is normalized by using the intensity of the regular reflected light measured using a barium sulfate standard diffuser plate in the same measurement - reflected light Strength value. The surface haze of the anti-glare film 1 is preferably 5 〇% or less, more preferably 3 or less. If the surface haze is 5 〇% or less, the appearance of the white turbidity of the anti-glare 减小 is reduced 'and' If the surface turbidity is 3 〇% or less, the appearance of the white turbidity of the anti-glare film is further reduced. . Surface turbidity is obtained by detecting surface scattering, and the higher the surface turbidity, the whiter the appearance of Vietnam. On the other hand, there is no specific limitation regarding internal turbidity. When internal turbidity is used herein, a turbidity meter HM-150 (manufactured and sold by MURAKAMI COLOR RESEARCH LABORATORY) is used, for example, under the test conditions described in Jis K7 136, relative to 142498.doc 16· 201003130 Glare film i (which has an adhesion.., 'The turbidity of the surface of the anti-glare layer 12 is i 0. / or less).

The difference between the obtained value and the internal turbidity is obtained by measuring the U and the internal expression with respect to the anti-glare film 1 by the same square error determined by the turbidity of the turbidity. An anti-glare film is obtained by forming a surface of the surface 14 with a fine-grained irregularity of the surface 14; The size of the expansion does not exceed the characteristics of the nine.

The average space between the diffuser elements (i.e., the average peak-to-valley space Sm of the surface 防 of the anti-glare film 1) is preferably 2 or more from the viewpoint of appropriately controlling the diffuse reflection characteristics and preventing coloration. From the viewpoint of the actual control characteristic of 142498.doc 201003130, it is preferably 50 μm or more. The resolution d(dpi) of a person (having vision V so that the person can distinguish between white and black with respect to a subject placed at a distance D (cm) from the person) is determined by the following formula:

d = 2.54 X 3,438 x V/D From this calculation, a person with a visual acuity of 1·〇 has a resolution of about 290 μm (μηι) at a viewing distance of 10 cm. Therefore, when the average peak_valley space Sm is considered to be within the above range, the appearance of the rough surface can be suppressed. The average peak-to-valley space Sm of the anti-glare film 1 is determined by measuring the surface according to the method described in m B0601-1994 by using, for example, SURFCORDER ET4000A manufactured and sold by Kosaka Laboratory Ltd. as an automatic micro-shape measuring instrument. The roughness parameter in the roughness curve obtained by the roughness. On the other hand, the surface glare is affected by the relationship between the space between the diffuser elements of the anti-glare film 1 and the pixel pitch, and therefore, it is preferable to control the space in accordance with the pixel pitch of the image display device used. When the space between the diffuser elements is not less than the pixel pitch, the relative positional relationship between the individual diffuser elements is not uniform, so it is recognized as surface glare. Therefore, when the space between the diffuser elements is 1/3 or less (more preferably 1/4 or less) of the pixel size of the image display device, surface glare can be prevented. The anti-glare film having fine irregularities in its surface in the first embodiment is composed of, for example, a resin. From the viewpoint of promoting production, the resin for the anti-glare film 1 includes an ionized Korean curable resin which is cured by, for example, ultraviolet light or electron light, and a thermosetting resin By the heat 142498.doc •18· 201003130

And curing), or at least one of thermoplastic resins. An acrylate resin (for example, urethane acrylate, epoxy acrylate, polyester acrylate, polyol acrylate, polyether acrylate, or melamine acrylate) can be used as the ionizing radiation-curable resin. . Regarding the characteristics of the cured resin, it is particularly preferable to produce a resin having a highly transparent cured resin (from the viewpoint of achieving image permeability) or a resin having a cured resin having a high hardness (from obtaining defect resistance) In view of this, a resin can be appropriately selected. The ionizing radiation-curable resin is not limited to the ultraviolet curable resin, and any ionizing radiation-curable resin may be used as long as it has light transmissivity, but it is preferable that the transmitted light color or the transmission pure amount is not caused by Ionized radiation-curable resin that changes color or turbidity. The photosensitive resin is obtained by a photopolymerization initiator and a capable of forming a resin-containing lanthanum material (e.g., an early precursor, an oligomer, or a polymer). For example, an acrylamide can be obtained by reacting a monomer or a prepolymer of isocyanate with a poly-glycol and reacting a monomer having a trans-acrylic acid or a methyl (tetra) acid g with the obtained product. Carbamate resin. , from the mouth into the π v Gekou j ^ ----, ~ work milk, as far as the G ketone ketones, hydrazine derivatives, etc. as a light-collecting person, especially take the mouth initiator. In the photosensitive resin, a component for promoting the formation of the sergeant, the upper sputum, such as propylene resin, can be appropriately selected and incorporated. If necessary, a light stabilizer, an ultraviolet light absorber, an antistatic agent, a retarder, and the like may be added to the photosensitive resin. Fine particles such as vermiculite can be added as a viscosity modifier. Method of manufacturing an anti-glare film by adding 7 (1-2) 142498.doc -19- 201003130 A method of manufacturing the anti-glare film 1 according to a first embodiment will be described with reference to Figs. 2A to 2E. (Procedure for preparing the master mold) The first preparation material is to be processed. Examples of the form of the base material include a substrate form, a sheet form, a film form, and a block form. Examples of materials for the base material include plastic, metal, and glass. Next, a mask imaging method (which uses, for example, KrF excimer laser), a pressing method, a method of molding using a stamper, a cutting method, a sandblasting method, a wet etching method, etc., are used. The base material is treated to pattern fine irregularities corresponding to the surface 14 of the anti-glare film 1 in the surface of the base material, thereby obtaining the master mold 21 shown in Fig. 2A, the shape of the fine irregularities and the surface 14 The shape of the subtle irregularities is reversed. The surface of the mother mold door has minute irregularities such that the anti-glare film 1 can achieve the diffuse reflection characteristics as described above, and has an average peak-to-valley space of 300 μm or less (preferably 22 μm or less). Sm. (Procedure for preparing a replica master) Next, a conductive film is formed on the fine irregularities of the master mold 21 obtained above by, for example, electroless plating. The conductive film is a metal film made of a metal such as nickel. Next, the master mold 21 on which the conductive film is formed is placed in an electroforming apparatus, and a metal electric ore layer is formed on the conductive film by, for example, an electric ore method, and your force is from a lA ^ 0 Also, for example, nickel plating. Next, the metal plating layer is separated from the master mold 21, and the replica master 22 shown in Fig. 2B is obtained, and the shape of the fine irregularities is opposite to the shape of the minute irregularities in the master mold 21. The replication master 22 as known above is then subjected to a surface treatment, and then a metal plating layer such as a nickel plating layer is formed on the fine irregularities of the resulting replica master by, for example, an electroplating method. The metal plating layer is then removed from the replica master 22' to thereby obtain the replica master 23 shown in Fig. 2C, the fine irregularities of which are the same as the fine irregularities of the master mold 21. When the master mold is composed of an organic substance or the like (which may be damaged), a sub-mold and a third-generation mold are prepared from the master mold as described above, and even when the master mold is damaged due to mold release from the mother strand, A large number of third generation molds were also prepared using a sub-mold. On the other hand, when the master mold is unlikely to be damaged and the child cooker can be repeatedly prepared from the master mold, the 4 ΐ mother mold is made to have the same shape as the anti-glare layer and the resulting reverse sub-mold can be used as the transfer mold. (Procedure for preparing an anti-glare film) Injecting a photosensitive resin (for example, an ultraviolet curing resin) Next,

The turbidity or surface shape is finely controlled to fine irregularities so that the light: transfer obtains the fine irregular irregular fine particles of the surface 14, but it is possible to add fine sewing for the photosensitive resin.

142498.doc 201003130 娆. Therefore, by using an anti-glare filmer in a display device such as a liquid crystal display, a plasma display, an electroluminescence display, or a CRT display, it is possible to provide a display that achieves both excellent anti-glare characteristics and excellent contrast. This improves visibility. (2) Second embodiment (2-1) Structure of anti-glare film Fig. 3 is an enlarged cross-sectional view showing an example of the structure of an anti-glare film according to a second embodiment of the present invention. The anti-glare film 丨 includes a substrate π, and an anti-glare layer 12 (having fine particles 13 formed on the substrate u). The fine particles 13 form a plurality of protrusions in the surface of the anti-glare layer 12 as a diffusion benefit member. Therefore, the surfaces of the anti-glare layer 12 have a fine 4 irregularities in common. The present inventors have conducted extensive and intensive studies on the diffuse reflection characteristics of the anti-glare film i. Therefore, it has been found that the specific diffuse reflection specific anti-glare film i described below can achieve excellent anti-glare characteristics and suppression of the appearance of white stain, and this anti-glare film has been successfully obtained. In order to achieve anti-glare characteristics, it is necessary to reduce the absolute value of the intensity of the regularly reflected light. However, it is more desirable that the diffuse reflection characteristics do not change abruptly. There is a correlation between the visibility of the human and the logarithm of the intensity of the light. Therefore, when the logarithm of the diffuse reflection characteristic changes sharply, the edge of the reflection of the light source in the surface is visually recognized, and thus the surface does not exhibit anti-glare characteristics. The anti-glare 臈 1 according to the embodiment of the present invention is satisfied so as to be 5 with respect to the normal line 2 of the surface of the anti-glare layer 2 as shown in Fig. 4 . To 3 〇. The diffuse reflection characteristic of the light incident on the surface in the direction 3 of the angle, ι(α+ι)/ι(α) ratio is: 1 such that i (〇c) is 1 与 with the mirror direction 4 . Or any smaller angle is the intensity of the reflected light in the direction 5 of 142498.doc -22- 201003130, and Ι(α+1) deviates from the angle α in the wide-angle direction! The intensity of the reflected light in direction 6. In this case, the change in the logarithm of the intensity of the reflected light may be smaller or smaller, and thus the edge of the reflection is no longer apparent, so that anti-glare characteristics are obtained. On the other hand, when the ratio of Ι(α+1)/ΐ(α) of the intensity of the reflected light is increased, the anti-glare property can be obtained, but the appearance of white turbidity becomes strong. Therefore, the ratio of Ι(α+1)/Ι(α) of the intensity of reflected light is 〇·6 or less. Figure 5 is a graph showing the mirror direction as the pupil of the light incident on the surface of the anti-glare layer 12. An example of the relationship between the angle of time (α) and the intensity of reflected light 1 (the illusion. The arrow in the figure indicates the full width of the angle at which the intensity of the reflected light is 1/100 of the peak value of the intensity of the reflected light. The inventors have It is found that the light incident on the surface in the direction 3 of the angle of 5 to 30 with respect to the normal 2 of the surface of the anti-glare layer 12 is at the intensity of the moo reflected light with respect to the peak of the intensity of the reflected light. The full width of the angle is 6〇. To 28〇. The day ^· 'can achieve the anti-glare characteristics similar to the above specific diffuse reflection characteristics. When the full width of this angle is less than 6.0, the intensity changes very sharply so that The edge of the reflection is observed. On the other hand, when the full width of the angle is greater than 28_0°, the anti-glare property is obtained, but the appearance of white turbidity is exhibited. Similarly, it has been found that the normal to the surface of the anti-glare layer 12 The light incident on the surface in the direction 3 of 5° to 3 0. The total width of the angle at the intensity of the reflected light is 10.0° with respect to 1/1 of the peak of the intensity of the reflected light. 45.0. When obtained with the above specific diffusion reflection Similar anti-glare characteristics. The full width of the angle at which the intensity of the reflected light is 1/1 相对 relative to the peak can be similarly specified, but the gloss is such that the surface of the reflected surface can be seen to expand 142498.doc -23- 201003130 The diffuse reflection features of the surface with appropriate anti-glare properties are similar to one another at an angle of about 1/10 intensity, and it has been found that anti-glare properties are not obtained by simply specifying diffuse reflection features. By using, for example, 0PTEC co The goniophotometer GP manufactured and sold by the company refers to measuring the intensity of the reflected light to determine the diffuse reflection characteristic of the anti-glare film i. In this measurement, the effect of removing the reflection from the back surface is determined in essence. The anti-glare film has a diffuse reflection characteristic, and a black glass or black acrylic plate is adhered to the anti-glare film on the surface of the anti-glare film 12 through an adhesive. On the other hand, the white is dirty. The appearance is 10 or more than the specular reflection direction. The reason for this is that the angle is greater than the angle between the specular reflection direction and the surface normal. The diffused light component can reduce white turbidity. Therefore, in the anti-glare film 1 according to the first embodiment of the present invention, it is satisfied that the anti-glare film 1 with respect to the surface of the anti-glare layer 12 is 5. 30. The angle of the light incident on the surface in the direction 3 is such that the gain of the light reflected in the direction of the specular reflection direction of 20 or more is 0_02 or less, more preferably 〇.01 or less. (The intensity of specularly reflected light from a standard diffuser plate is normalized as a chirp to normalize the gain), and is advantageously reflected in the direction of the specular reflection. The gain of the light is 〇25 or less, more preferably 〇·08 or less. In this case, the appearance of white turbidity in the anti-glare film can be suppressed. As used herein, "increasing" means a reflected light intensity normalized using a standard diffuser plate, and in one embodiment of the invention the 'increase line' will use a barium sulfate standard for the same measurement. The intensity of the regular reflected light of the amount of 142498.doc -24- 201003130 measured by the diffuser plate is used as a reflected light intensity value normalized by 1. The surface turbidity of the anti-glare film 1 is preferably 5 〇% or less, More preferably, it is 3 〇0 / 〇 or less. ^ Surface turbidity is 5 · 0% or less, reducing the appearance of white turbidity of the anti-glare film - and when the surface turbidity is 3 〇 % or less, Further reducing the appearance of the white turbidity of the anti-glare film. The surface turbidity is obtained by detecting the surface illuminating, and the higher the surface turbidity, the more the appearance of white turbidity. On the other hand, The internal turbidity is not particularly limited, and the internal turbidity is determined depending on the fine particles 13 and the like contained in the anti-glare layer 12. In one embodiment of the present invention, by, for example, the description in jIS K7136 Using a turbidity meter HM-1 50 under measurement conditions (by MURAKAMI COLO R RESEARCH LABORATORY manufactures and sells an anti-glare film 1 (having an adhesive having a haze of 1% or less adhered to the surface of the anti-glare layer 12) to determine the internal turbidity. The turbidity is determined in the same manner as the anti-glare film 丨 to determine the surface turbidity, and the difference between the obtained value and the internal turbidity is obtained. The surface of the anti-glare layer 12 is formed on the surface of the anti-glare layer 12. A diffuser element with fine irregularities obtains such optical characteristics of the anti-glare film. By reducing the size of the diffuser element, the screen is flickered, or glare due to the appearance of the rough surface of the surface (hereinafter The glare of the screen is often referred to as "surface glare," which can be suppressed. The rough surface appearance of the surface means that the light source having a uniform light intensity is reflected from the diffuser element in different directions when reflected from the anti-glare film 1. The resulting uneven luminosity from the surface. Therefore, it is advantageous to reduce the space between the 142498.doc -25- 201003130 components so that the image is used in the anti-glare film! The individual diffuser elements can be separated from one another when viewed at a distance. Clearly, the diffuser element is specified by volume diffusion by reducing the average space between the diffuser elements or by surface diffusion to specify diffusion. The device element can suppress the appearance of the rough surface by reducing the j average peak_valley space § 111. The anti-glare filmmaker according to the second embodiment of the present invention satisfies the average space between the diffuser elements (ie, anti-glare) The average peak-to-valley space 8 of the surface of layer 12 is called 3 〇〇 ^ melon or smaller, preferably pm or less. From the viewpoint of appropriately controlling the diffuse reflection characteristics and preventing coloration, between the diffuser elements The average space (i.e., the average peak-to-valley space Sm of the surface of the anti-glare layer 12) is preferably 2 or more, and is preferably 5 μm or more from the viewpoint of actual control characteristics. The resolution d(dpi) of a person (having vision V so that the person can distinguish between white and black with respect to a subject placed at a distance from the person) is determined by the following formula:

d = 2.54 X 3,438 x V/D From this calculation, a person with a visual acuity of 1.0 has a resolution of about 290 micrometers (μιη) at a viewing distance of 100 cm (cm). Therefore, when the average peak_valley space Sm is considered to be within the above range, the appearance of the rough surface can be reduced. The average peak-to-valley space Sm of the anti-glare film 1 is determined by the method described in jis B060 1 - 994 by using, for example, SURFCORDER ET4000A manufactured and sold by Kosaka Laboratory Ltd. as an automatic micro-shape measuring instrument. The coarseness parameter in the roughness curve obtained by measuring the surface roughness. 142498.doc -26- 201003130, like: "The relationship between the diffuser elements of the anti-glare film 1:: the relationship between the turns, therefore, it is better to control the space according to the pixel pitch of the use of the heart device. Diffuser components Between: = at the pixel pitch, the relative position between the individual diffuser elements is thus recognized as surface glare. The space of the diffuser element is 1/3 or less of the pixel size of the image display device (more preferably / Or smaller, it can prevent surface glare.

The anti-glare layer 12 (which is a fine irregularity having a surface) according to the second embodiment of the present invention includes (10) a tree moon comprising fine particles 13 as it is. In the fine irregularities of the surface, it is preferred to cover the fine particles 13 by a resin (e.g., ionization-rolling-curable resin). The irregularities may be moderately inclined irregularities, and 'for example, preferably a plurality of fine particles U are cohesively dispersed in an in-plane direction to form a diffuser element. A resin (for example, ionized light-curable resin or tamping resin) may be used to cover the entire surface of the adhered fine particles 13 or may expose the surface of the fine particles 13 (as long as the diffusion reflection characteristics mentioned above are satisfied) ). Not =, when the fine particles 13 protrude from the anti-glare layer 12 to form a large inclination of 4 knives, it is difficult to satisfy the above diffuse reflection characteristics, and thus the surface may have a rough surface appearance. Therefore, when the surface of the fine particles 13 is exposed, it is preferable that the portion of the surface of the fine particles 13 located only at the tip end portion 7 of the protrusion serving as the diffuser member is the exposed portion. As used herein, the term "plurality of fine particles 丨 3 is cohesive in an in-plane direction in an appropriate manner" means: (1) all fine particles 13 are only cohesive in the in-plane direction and not in the anti-glare layer 12 Stacked in the thickness direction; or (2) 142498.doc -27- 201003130 Almost all fine particles 13 are cohesive in the in-plane direction and the remaining fine particles 13 are stacked on each other in the thickness direction so that the white stain does not increase ( Up to 2.0, measured using black glass flakes.) All fine particles are ideally formed as two-dimensional binders' but portions of fine particles 13 may separate from each other without forming a binder and thus the white stain does not increase. The resin used in the glare layer 12, from the viewpoint of promoting production, an ionizing radiation-curable resin (which can be cured by irradiation with, for example, ultraviolet light or electron beam), or a thermosetting resin (its It is preferably cured by heat. Preferably, the photosensitive resin (which can be cured by irradiation with ultraviolet light) is optimal. An acrylate resin (for example, acrylamide acrylate) can be used. , epoxy acrylate vinegar, polyester acrylate, polyol acryl vinegar, poly-acrylic styrene, or melamine acryl vinegar) as a photosensitive resin. Regarding the characteristics of the cured resin, a particularly good system can produce excellent light transmittance. A resin that cures the resin (from the viewpoint of achieving image transparency) or a resin that can produce a cured resin having a high hardness (from the viewpoint of obtaining resistance to defects), and a resin can be appropriately selected. Ionized radiation - The curable resin is not limited to the ultraviolet curable resin, and any ionizing radiation-curable resin (as long as it has light transmissivity) can be used, but it is preferred that the color of transmitted light or the amount of transmitted light is not due to coloring or turbidity. A significantly different ionizing radiation-curable resin obtains a photosensitive resin by incorporating a photopolymerization initiator into an organic material capable of forming a resin such as a monomer, an oligomer, or a polymer. For example, by making an isocyanate single The precursor or prepolymer reacts with the polyester polyol and reacts the acrylate or mercapto acrylate monomer having a hydroxyl group with the resulting product to obtain propylene Acid urethane resin 142498.doc -28- 201003130 may be used as a photopolymerization initiator, for example, in the case of diphenyl g, biological, phenethyl hydrazine derivative, or the like. It can be appropriately selected and incorporated into a component for promoting film formation, such as acrylic resin. 0 If necessary, in (4) Resin _ Add appropriate amount of light stabilizer, ultraviolet light absorbing agent, antistatic agent, flame retardant , antioxidants, etc.. It is possible to add Shi Xi Shi fine particles as a viscosity modifier. Use, for example, organic fine (tetra) or money filaments as fine particles 13 ° beads can be used (for example, acryl, styrene, (4) styrene copolymerization, melamine, or polycarbonate S beads) as organic fine particles. It may be crosslinked or non-crosslinked' and any spherical or flat fine particles containing plastic may be used. Using, for example, an average particle diameter of 5 nanometers (s) to 15 micrometers (_ fine particles as fine particles 13). When the average particle diameter of fine particles is greater than 15 Å, light reflected from the surface adversely causes glare On the other hand, when the average particle diameter is 5 nm, the particles dispersed when the coating composition is prepared are disadvantageously re-adhered. The average particle diameter of the fine particles 13 can be measured by, for example, a laser diffraction method. The anti-glare film 1 may have (although not shown to contain a filler or a layer containing no filler on the anti-glare layer 12), that is, the anti-glare layer is composed of two layers. Using, for example, a plastic film having transparency As the substrate u, a heat-sensitive polymer film can be used as the film. Specifically, it can be obtained from a well-known tree sorghum (for example, cellulose triacetate, polyester, polyethylene terephthalate (PET). , Polyimine (PI), polyamine, aromatic polyamine, polyethylene, 曰142498.doc -29- 201003130 Polyacrylate, polyether bowl, polyfluorene, cellulose diacetate, polypropylene, poly Gas ethylene, acrylic resin, polycarbon A polymer film is appropriately selected from the films of esters, epoxy resins, urea resins, urethane s-resin resins, and hydrazine, amine resins. The substrate is not limited to the film 'and', for example, an inclusion can be used. The thickness of the substrate π is not particularly limited, and the thickness is appropriately selected. From the viewpoint of excellent productivity, the thickness of the substrate is preferably from 38 to 100 μm. However, the thickness is not limited to this range. (2-2) Method of manufacturing an anti-glare film

Next, a method of manufacturing the anti-glare film 1 according to a second embodiment of the present invention will be explained. Mixing solvent with, for example, the above-mentioned ionized light-curable resin, fine particles 13, and (as needed) light stabilizers, ultraviolet light absorbers, antistatic agents, flame retardants, antioxidants Etc. to prepare a coating composition having fine particles i 3 in the middle of the knife. Regarding the solvent, there is no special system, and 1 can be used - an organic solvent such as tert-butanol, toluene 'methyl ethyl ketone (MEK), or isopropyl alcohol (IpA) D. The substance is substantially uniformly applied to the substrate 11 mentioned above. Regarding the method of applying the coating composition, there is no special branching, and a well-known coating method can be used. Examples of the coating method include a micro gravure coating method, a bar coating right f, a soil, a _ soil cloth method, a direct gravure coating method, a die coating method, a shell method, a spray coating method, a reverse roll coating method, and an inexpensive method. , comma coating method, doctor blade coating method, and spinning method. Regarding the thickness of the coating composition, the thickness of the layer composition is appropriately controlled and applied to the solid content of the coating group 142498.doc -30- 201003130 so that the dried average thickness becomes 3 to 3 〇μιη Preferably, it becomes 4 to 15 μm. When the thickness is less than the above range, it is difficult to obtain the desired hardness' and when the thickness is larger than the above range, the resulting film may be subjected to significant curling. After coating, the applied coating composition is dried at elevated temperature to volatilize the solvent. The convection caused by the coating composition during the dry olefin formation forms the Benadle cell, and the surface of the anti-glare layer 12 is provided with a moderately inclined irregularity with an appropriate period. In the anti-glare film 2 according to a second embodiment, the diffuser element is formed not by, for example, uniformly dispersing the individual fine particles 13 but by allowing a plurality of fine particles 13 to be appropriately cohesive (due to convection) to form a diffuser element. And get the surface of the desired surface. The boiling point of the solvent contained in the visible coating composition appropriately determines the drying temperature and the drying time. In this case, it is preferred to select the drying temperature and the drying time so that the substrate 丨丨 is not deformed by heat shrinkage while considering the thermal resistance of the substrate. In addition, better control of drying conditions and other factors results in proper convection in the ionizing radiation curable resin to produce the desired surface shape. The drying step and the curing step will be described in detail below. The coating composition applied to the substrate crucible is first dried at a predetermined temperature to cause convection in the coating composition so that the fine particles 13 are appropriately cohesive in the in-plane direction due to convection to form a two-dimensional binder. In this example, the solvent is allowed to form and the Benadene cells are formed in the surface of the coated film. When the fine particles 13 are stacked on each other in the thickness direction of the coated film to form a three-dimensional adhesive, the composition having an acute angle is disadvantageously formed in the surface of the anti-glare layer, thereby increasing the appearance of white stain. 142498.doc -31 - 201003130 The term "Benadine cell" as used herein, means a surface formed during the solvent drying step due to convection or convection caused by the coating composition. All surface structures formed are referred to as: used in the text, Bernard, and have any form, in a tubular structure. The surface tension can be controlled by, for example, the surface tension of the solvent and fine particles. The amount of fine particle 丨3 is selected to be selected. Preferably, after the coating composition is dried, the resin contained in the coating composition is also in a liquid state. In this case, a bend can be formed between the Benadite cells. The lunar surface makes it possible to produce a moderately inclined rule in the surface of the coated film. 〃 Regarding the drying conditions, there is no particular limitation, and air drying or artificial drying may be employed in which the drying temperature or drying time is controlled. When the rolling flow is transmitted to the surface of the coating composition, it is preferred not to cause a wind pattern in the surface of the coated film. When the wind pattern is caused, it is impossible to prevent In the surface of the crucible, it is necessary to moderately tilt the fine irregularities, thus making it difficult to achieve both the smear and the high contrast. Next, the substrate is cured by dissociating radiation or heating. The dry tree I thus forms a waveform having a large period of time - a two-dimensional adhesive composition-peak. That is, 'the anti-glare layer is formed in the surface with a wide period and a moderate slope (with irregularities in the film currently manufactured) Compared to) fine irregularities. Examples of curing ionized light shots. Curable resins to form an anti-glare layer to cure energy include electron beam, ultraviolet light, visible light, and gamma 142498.doc -32- 201003130 Line 'But from the viewpoint of production promotion, ultraviolet light is preferred. Regarding the ultraviolet light source, there is no particular limitation, and a high-pressure mercury lamp, a metallized lamp, etc. are appropriately selected. The total irradiation amount can be appropriately selected - total The amount of irradiation is such that the resin used is cured and the resin and the substrate u are not subjected to yellowing. The curing of the resin is appropriately selected to be an irradiation environment and can be carried out in an inert atmosphere such as air or nitrogen or argon. The anti-glare film 1 prepared by the above method has a specific diffusing reflection characteristic as described above, thereby suppressing the appearance of white stain while achieving anti-glare characteristics. Further, the anti-glare film has an anti-glare film formed thereon. a specific space between the diffuser elements in the surface of layer 12, thus the anti-glare film has reduced the appearance of the rough surface. Because &, by display devices (such as liquid crystal displays, plasma displays, electroluminescent displays, The anti-glare film 1 is used in a CRT display or the like, and a display that achieves both excellent anti-glare characteristics and excellent contrast can be obtained, thereby improving visibility. (3) Third embodiment (3-1) Anti-glare film group As shown in FIG. 4, an anti-glare film 1 according to a third embodiment of the present invention includes an anti-glare layer 12 formed on a substrate u, and forms a plurality of diffuser elements in the surface of the anti-glare layer 12. Protrusions, and the surfaces collectively have fine irregularities. A fine pattern in the surface of the anti-glare layer 12 is formed by a shape transfer method using a replica master prepared by a master mold which is formed by microfabrication. The substrate 11 in the third embodiment of the present invention, the diffuse reflection feature, and the average space between the diffuser elements are similar to the substrate in the first and second embodiments of the present invention 142498.doc -33· 201003130

The anti-glare layer 12 in the third embodiment of the present invention is formed of a resin including an ionizing radiation-curable resin or a thermosetting resin which is similar to the resin of the first and second embodiments of the present invention. . The desired irregularities in the surface of the anti-glare layer 12 are obtained by using a replica master to impart irregularities to the surface of the molded surface using a replica master as described below. The anti-glare layer must contain fine particles 13' but it may contain fine particles 13 for fine control of turbidity or surface shape. (3-2) Method of manufacturing an anti-glare film Next, a method of manufacturing the anti-glare film 1 according to a third embodiment of the present invention will be described with reference to Figs. 7A to 7B. The procedure for preparing the master mold is first prepared - the substrate material to be treated. Examples of the form of the base material include a substrate form, a sheet form, a film form, and a block form. Examples of materials for the base material include plastic, metal, and glass. Next, a mask imaging method (which uses, for example, KrF excimer laser), a pressing method, a method of molding using a stamper, a cutting method, a sandblasting method, and a wet etching method are used. The base material is processed to be on the surface of the base material: the fine irregularities corresponding to the surface of the anti-glare layer 12 are patterned, and the shape of the fine irregular shape and the anti-glare layer u as shown in FIG. 7A are known. The shape of the subtle irregularities in the opposite is opposite. The surface of the master mold 21 has such that the anti-glare film 依据 according to the third embodiment of the present invention can achieve a diffusion inverse similar to the diffuse reflection characteristics of the first and second embodiments of the present invention. 142498.doc • 34· 201003130 A subtle irregularity of the characteristic, and preferably has an average peak-to-valley space Sm of a matrix or smaller, more preferably 22 〇μΐΏ4. Procedure for preparing a replica master Next, a conductive film is formed on the fine irregularities of the master mold 21 obtained above by, for example, electroless plating. The conductive film is a metal film composed of a metal such as nickel. Next, the master mold 21 on which the conductive film is formed is placed in an electroforming apparatus, and a metal key layer such as a deposit layer is formed on the conductive film by, for example, a shovel method. Next, the metal electric key layer is separated from the mother board 21, and the replica master 22 shown in Fig. 7; 6 is obtained, and the shape of the fine irregularities is opposite to the shape of the minute irregularities in the master mold 21. Thereafter, the replica master 22 obtained as described above is subjected to surface treatment, and second: a metal plating layer such as a nickel plating layer is formed on the fine irregularities of the resulting replica master by, for example, an electric ore method. Next, the metal plating layer is removed from the replica master 22 to obtain a replica master 23 as shown in Fig. 5C, the fine irregularities of which are the same as the fine irregularities of the master mold 21. When the master mold is composed of an organic substance or the like (which may be damaged), the master mold and the third-generation mold are prepared from the master mold as described above and even when the master mold is damaged due to demolding of the master mold, A large number of third generation molds can be prepared using a sub-mold. On the other hand, when the master mold is unlikely to be damaged and the sub-mold can be repeatedly prepared from the master mold, the master mold is processed so that its shape is the same as that of the anti-glare layer and the resulting reverse sub-mold can be used as the transfer mold.

H2498.doc -35 - 201003130 can be used, for example, as a photosensitive resin for the anti-glare layer 12, which is similar to the resin used in the first embodiment of the present invention. The fine irregularities of the anti-glare layer 12 are obtained by shape transfer, so that it is not necessary to add fine particles to the photosensitive resin, but fine particles can be added to the photosensitive resin in order to finely control the haze or the surface shape. Next, as shown in Fig. 7D, a substrate u serving as a supporting substrate is placed on the replica master 23. Subsequently, the thickness of the photosensitive resin is made uniform by applying a force to the substrate 11 by, for example, a rubber roller. Next, for example, the photosensitive tree is cured by irradiation of, for example, a substrate 光线 with light (e.g., ultraviolet light). Next, as shown in Fig. 5E, the cured photosensitive resin is released from the replica master 23. Therefore, the anti-glare layer 12 is formed on one main surface of the substrate 11, and an anti-glare film 1 having the diffuse reflection characteristics as described above is prepared. Fig. 8 is a view showing an example of a configuration of a liquid crystal display device using the anti-glare film 1 according to the third embodiment of the present invention. As shown in Fig. 8, the liquid crystal display device includes a liquid crystal panel. 3 1 and a light source 33 provided under the liquid crystal panel 31, and the liquid crystal panel 31 has an anti-glare film 1 on its display side. The light source 33 supplies light to the liquid crystal panel 3, and has, for example, a fluorescent lamp (FL), an electroluminescence (EL), or a light-emitting diode. The liquid crystal panel η modulates the light supplied by the light source 33 to display information. A polarizer is provided on both surfaces of the liquid crystal panel 3 i Sheets 32a, 32b. The polarizer sheet 3 passes through the sheets with the polarized film 32b allowing the polarized light perpendicular to the incident light to pass through the sheets and occlude the other by absorption. The polarizer sheet 32a and the polarized light The sheet 32b is configured such that, for example, its transmission axis hangs 142498.doc -36-201003130 straight 0

According to a third specific embodiment of the present invention, the specific diffuse reflection characteristic is thus made to be white and dirty. In addition, the optical film between the diffuser elements in the surface of the layer 12 has reduced the appearance of the rough surface. The display can be improved due to the use of the anti-glare film 1; visibility. The anti-glare film of the example has the anti-glare property as described above, and the anti-glare film has a specific space formed in the anti-glare, so the anti-glare is obtained by eating the liquid crystal display device in the liquid crystal display device.

In Fig. 9, L1 corresponds to the example 丨, L2 corresponds to the example 2, and L3 corresponds to the comparative example 2. Figure 1A shows a graph showing the individual diffuse reflection features of Examples 3 and 6 and Comparative Example 4. In Fig. 1 , μ corresponds to Example 3, L5 corresponds to Example 6, and “corresponds to Comparative Example 4. The evaluation items of the diffuse reflection characteristic are as follows. The ratio of Ι(α+1)/Ι(α) is determined, where 1 ( a) is the intensity of the reflected light at an arbitrary angle α and Ι(α+1) is the intensity of the reflected light which is deviated from the angle a by an angle a in the wide-angle direction, and the ratio of the intensity of the reflected light is determined to be a large value. 1.

The intensity of the light reflected in the specular reflection direction measured using a standard diffuser plate (which is composed of barium sulfate) is used as a standardization relative to the anti-glare films of Examples 丨 to 9 and Comparative Examples 丨 to 5. The anti-glare film has a specular reflection direction of 2 Å. The intensity of the reflected light in the direction determines a gain. The measurement of the turbidity is measured using the HM_150 under the measurement conditions described in JIS K7136 (^ MURAKAMI COLOR RESEARCH LABORATORYt manufacture and lock) measure turbidity. Relative to examples and comparative examples (1) The anti-glare film is measured for a turbidity and is attached to the surface of the anti-glare layer of the above anti-glare film by attaching a binder (having a turbidity of 142498.doc • 43-201003130 degrees of 1% or less) The obtained anti-glare film measures a turbidity, and the latter is defined as the internal turbidity, and the difference between the former and the latter is determined as the surface turbidity. The measurement of the average space between the diffuser elements is related to the example! to 9 and the comparative example (1) Each of the anti-glare films of the anti-glare films is measured under the measurement conditions described in JIS B0601_1994 using an automatic micro-shape measuring instrument SURFC〇RDER ET4〇〇〇a (manufactured and sold by K〇saka Laboratory Ltd.) The surface roughness is obtained from the obtained two-dimensional section curve. As a rough seam parameter, the average length Sm of the trimming curve is determined by the row-calculation to determine the average space between the diffuser elements.

Then, a light-emitting illumination (which has two unshielded fluorescent lamps arranged in parallel) is used as a light source, and is reflected from the specular surface. Visual inspection of the direction to check the reflection in each anti-glare film, and evaluate the reflection of the fluorescent illumination according to the following criteria: A. The edge of the fluorescent lamp cannot be seen. (The two fluorescent lamps are regarded as light.) B : Fluorescent lamps can be seen to some extent, but the edges are not obvious. C: Directly reflecting fluorescent lamps. Evaluation of white turbidity 142498.doc -44· 201003130 by diffusing the surface of the anti-glare layer from the surface Reflective political light is detected as a light source (such as fluorescent lighting) to sense the appearance of white turbidity. Therefore, the value determined by using a commercially available spectral colorimeter to simulate the above phenomenon is used as white stain. A specific method of measuring white stain is as follows. First, regarding the anti-glare films of the anti-glare films prepared in Examples 1 to 9 and Comparative Examples 1 to 5, "the effect of removing the reflection from the rear surface is removed to substantially evaluate the diffusion reflection of the anti-glare film. The back surface is attached to the black glass through a binder. Next, using an integrated ball 3L chromaticity „10 SP64 (manufactured and sold by X_Rite, inc〇rp〇rate (j), using a d/8 optical system in which diffused light is used to illuminate the surface of each anti-glare film And the reflected light is measured by a detector (which is located in the direction of 8 from the normal of the anti-glare film). Regarding the measured value, the spEx mode is adopted (in which only the measured diffuse reflection component and the specular component are excluded) And the measurement is performed at a detection angle of 2. The experiment has confirmed that there is a correlation between the white turbidity measured by the above method and the white turbidity of the visual sense. About Examples 1 to 9 and the ratio; Each of the anti-glare films of the anti-glare films prepared in Examples 1 to 5 is attached to the black acrylic sheet (ACRYLITE L. 502, through the adhesive_adhesive).

The change in maximum strength. In each of the examples from the example to 9 (where the maximum intensity change per one is greater than 〇1), the edge of the fluorescent lamp is not noticeable in the evaluation of the anti-glare characteristics, so the films are graded to a grade. B, and found to have appropriate anti-glare properties. Conversely, in Comparative Examples 3 and 4 (where the maximum intensity change per 丨 is 〇丨 or smaller), the reflection of the fluorescent illumination is observed in the evaluation of the anti-glare characteristics, and the films do not have a Satisfactory anti-glare properties. From the above results, it has been found to achieve anti-glare properties, each time. The maximum intensity change is greater than 〇.丨. In Comparative Examples 1 and 2, in which the maximum intensity per 1 is greater than 〇1, the films have excellent anti-glare properties, but along the 20th. The gain is up to 〇.02 or larger and has a strong white smudge appearance. Thus every 1 has been found. The change in the maximum intensity is preferably 〇·6 or less. Next, focus on the full width of the angle at which the intensity of the reflected light is 1/100. In each of the examples 1 to 9 (where the full width of the angle is 6 〇 or greater), the respective films exhibit appropriate anti-glare characteristics. On the contrary, in Comparative Examples 3 and 4 (where the full width of the angle is less than 6.0), the reflection of the fluorescent illumination is observed by visual observation in the evaluation of the anti-glare characteristic, and the films are not satisfactory. Anti-glare properties. In Comparative Examples 1 and 2 (where the full width of the angle is greater than 28.0°), the films have excellent anti-glare properties, but they are along 2 turns. The gain is greater than 0 02 and has a strong white smudge appearance. From the above results, it has been found that in order to achieve anti-glare characteristics, the full width of the angle of 1 / 1 〇〇 reflected light intensity must be 6.0. To 28.0. . Next, focus on 1/1, the full width of the angle at which the intensity of the reflected light is reflected. In each of the examples 1 to 9 (where the full width of the angle is ι〇·〇 or larger), each film 142498.doc 50-201003130 achieves appropriate anti-glare characteristics. On the other hand, in Comparative Examples 3 and 4 (where the full width of the angle is less than 10.0.), the reflection of the fluorescent illumination is observed by visual observation in the evaluation of the anti-glare characteristic and the films are not satisfactory. Anti-glare properties. In Comparative Examples 1 and 2 (where the full width of the angle is greater than 45.0°), the films have excellent anti-glare properties, but along the 2 〇. The gain is greater than 0,02 and has a strong white stain appearance. From the above results, it has been found that to achieve anti-glare characteristics, the full width of the angle at 1/1,000 reflected light intensity should be 10.0° to 45.0. . Pay attention to the full width (half bandwidth) of the angle at 1 1/2 reflected light intensity. The half-bandwidth with respect to the peak value of the reflected light intensity as described in Comparative Example 1 which satisfies the Japanese Unexamined Patent Application Publication No. 2-36541A is 7. Or greater, and the film achieves excellent anti-glare properties, but the film to which the black acrylic sheet is attached has a white stain of greater than 1 -7. Thus, it has been found that it is difficult to achieve both excellent anti-glare characteristics and reduced white stain. In addition, a comparison of Comparative Examples 3 and 4 (where the anti-glare characteristics were unsatisfactory) and Example 5 (where appropriate anti-glare characteristics were achieved) revealed no half-bandwidth relationship therebetween. From the above, it has been found that a film having a full width of only a specific angle at a intensity of 1/2 reflected light cannot achieve anti-glare characteristics. It is speculated that the reason is that there is a correlation between the visibility of the human and the logarithm of the intensity of light, and thus the intensity of light must be gradually reduced to 丨8 (8) or 1 /1,0 0 0 intensity. About by d/8. The whiteness > turbidity as assessed by the reflectance (except for the specular component) is 2〇 along in Examples 1-9. An anti-glare film having a gain of 〇〇2 or less and each having a black acryl plate adhered has a white turbidity of 1.7 or less. The anti-glare films each of which are attached with a black acrylic sheet in Examples 1 to 9 have a smaller white stain of 1.7 or 142498.doc -51 - 201003130, and have a reduced black reflection, so that the surface is displayed on the surface When using these films, black is clearly seen. In addition, the anti-glare films of the examples 2 and 4 to 9 each having a black acrylic plate have a whiteness of 1 > 2 or less > turbid Tang, Nissan, Du. ~ 蜀 degree and further reduction Small black reflections improve contrast and give image authenticity. On the contrary, compare the example of the heart along the 20th. An anti-glare film having a gain of 0.02 or more has a strong white stain appearance. In Comparative Examples 1 and 2, in which the appearance of white stain was strong, the surface turbidity system was more than 5.0%. From this, it was found that the surface haze is preferably from 〇% to 〇%. In each of Examples 2 to 9, the surface haze was 3% or less. From this, it was found that the surface turbidity was more preferably from 0% to 3%. On the other hand, the internal turbidity is determined without specifying the turbidity of the portion and by adding a fine particle having a surface opening/shape which can achieve the desired diffuse reflection characteristic. Next focus on the average space between the diffuser elements. Regarding each of the anti-glare films of the anti-glare films having an average space of 300 μm or less in the examples 丨 to 9, no reflection of the rough surface was observed in the reflection at the position of the anti-glare film (10) (4). Specifically, each of the anti-glare films of the anti-glare films having an average space of 22 μm or less in the examples i, 2, 4 to 6, 8 and 9 has a weight of about 50 cm even from the anti-glare film. Very fine surface features of the rough surface appearance were also not perceived at the location of (cm). On the other hand, regarding the anti-glare film having an average space larger than 330 in Comparative Example 5, the appearance of the rough surface was perceived, and the anti-glare film did not have a fine surface.
