Description

200804919 (1) Description of the Invention [Technical Field] The present invention relates to a liquid crystal display having improved anti-glare properties and an anti-glare polarizing film laminate for use in the liquid crystal display. ^ [Prior Art] Liquid crystal displays are increasingly used in portable TVs and notebook-sized personal computers, because they have good characteristics such as light weight, thickness, low energy consumption, and the like. Recently, such liquid crystal displays have also been gradually used for image monitoring devices, such as TVs with large screens and the like. In the case of a liquid crystal display for displaying a screen such as a television set, emphasis is placed on visibility, in particular, the contrast ratio when viewing the screen from the front and the contrast ratio when viewing the screen from the oblique direction, in other words, the viewing angle problem. In order to improve the viewing angle properties, different driving modes of the liquid crystal cells have been proposed. For a liquid crystal display having improved viewing angle properties, JP 2 548 979 B • discloses a vertical alignment (VA) type liquid crystal display in which a rod-shaped liquid crystal molecule having a positive or negative anisotropic dielectric constant is perpendicular to a substrate of a liquid crystal cell Align. Because, in the VA type, the liquid crystal molecules are aligned in the vertical direction with respect to the substrate of the liquid crystal cell in a state where the display is not driven, and light can pass through the liquid crystal layer without a change in the degree of polarization. Therefore, when a pair of linear polarizing plates are placed on the front and back sides of the liquid crystal panel such that the polarizing axes of the polarizing plates are at right angles to each other, a substantially completely black display can be seen from the front surface and thereby a high contrast ratio can be obtained. However, in the VA type liquid crystal display, only the linear polarizing plates placed on the liquid crystal cell 200804919 (2) are formed, and when the screen of the display is viewed obliquely, the polarizing axis of the linear polarizing plate is formed. The angle can be offset by 90 degrees and the rod-shaped liquid crystal molecules in the unit exhibit birefringence, so light leakage and thus the contrast ratio will be greatly reduced. In order to prevent light leakage from the VA liquid crystal display, a light compensation film should be provided between the liquid crystal cell and the linear polarizing plate. Finally, a two-axis blocking plate is inserted between the liquid crystal cell and the respective polarizing plates, or a single-axis blocking plate and a full double φ-axis blocking plate are placed on the front and back sides of the liquid crystal cell, or the second retarding plate is Placed on one of the surfaces of the liquid crystal display. For example, JP-A-20 (H-1 09009 discloses the insertion of an a-plate (ie, a positive uniaxial retardation plate) and a c-plate (a full dual-axis retardation plate) between a liquid crystal cell and a front and back polarizing plate, respectively. The VA type liquid crystal display. The positive uniaxial retardation plate means a retardation film having R 〇 / Rth of about 2, wherein Rq is an in-plane retardation 値 and Rth is a retardation 厚度 in the thickness direction. The full biaxial retardation The plate means a retardation film having an in-plane retardation 値R 约 of about 0. The φ is defined by the following equations (1) and (2) to define the in-plane retardation 値R〇 and the thickness direction delay 値Rth : R〇=( Nx-ny) xd (1)

Rth = [ ( nx + ny) / 2-nz] xd ( 2) where nx is the refractive index in the direction of the retardation axis of the in-plane phase, ny is the refractive index in the direction of the in-phase phase of the in-piane phase, nz is The refractive index in the thickness direction and d are the thickness of the film. 200804919 (3) In the case of a positive uniaxial retardation film, nz is almost equal to ny ( nz ^ ny ) and thus R 〇 / Rth is about 2 ( R 〇 / Rth ^ 2 ). Regarding the uniaxial retardation film, the R〇/Rth ratio can be about 1. 8 and 2. The variation within the range of 2 depends on the orientation of the film. In the case of the full biaxial retardation film, η χ is almost equal to ny (nx e ny ) and thus R 〇 is about 〇 ( R 〇 tri 〇 ). Regarding the full biaxial extension retardation film, since only the refractive index in the thickness direction is different from (less than) other refractive indices, the retardation film has a negative uniaxiality and thus is referred to as having a normal direction of φ. The film of the optical axis. In a biaxial retardation film, the refractive indices have this relationship: nx > ny > nz. The polarizing plate usually has a protective layer on at least one surface of the polarizing film. The protective layer typically comprises a triethylenesulfonated cellulose film. Different attempts have been made to replace the triethyl fluorene cellulose film or impart delayed properties to the protective layer using other resin films. For example, JP-A-08-43 8 1 2 describes at least one of a protective layer composed of a birefringent film as a polarizing film. JP-A-07-287123 discloses a protective layer made of a norbornene resin (cyclic olefin resin) made of a polarizing film. Further, image display devices such as liquid crystal displays will obviously lose their visibility when their image display screens reflect external light. Thus, in applications such as TVs, monitor screens for personal computers, etc. that impart image quality and visibility, the screen surface of the display device is typically processed to prevent reflection of external light. Regarding means for preventing reflection, it is preferable to use an anti-glare treatment in an application such as a large personal computer, a monitor, a TV, etc., which will form fine irregularities on the surface to scatter incident light and thereby blur the reflected image. Because this process is done at a moderate cost. Regarding the film which provides this anti-glare property, JP-A-2002-3654 1 0 discloses 200804919 (4) an optical film having fine irregularities formed thereon, wherein the reflected light mode satisfies when the light follows the normal-1 twist The direction of the angle enters the surface of the film and only the specific relationship of the reflected light from the surface is observed. 1?-八-2002-1 8 9 1 0 6 discloses an anti-glare film comprising a transparent resin film and a fine irregular ion-radiation curable resin layer, which can cure the resin layer by curing the ionizing radiation while The ionizing radiation curable resin layer is interposed between the embossing mold and the transparent resin film to form the fine irregularity, so that the three-dimensional 10 point flat φ average roughness and the adjacent convex portion of the three-dimensional surface roughness reference surface The average distance is formed on the surface of the transparent resin film within a specific range, respectively. JP-A-2004-90 1 87 discloses a method of manufacturing a roll for the manufacture of a film having a fine irregularity on its surface, which comprises forming a plated metal layer on the surface of the embossing roll, mirror honing The surface of the metallized layer is sprayed with a ceramic bead to the mirror-polished surface of the metallized layer, and the metallized layer is optionally hammered. φ In general, it may be necessary to use an anti-glare film with a high turbidity of at least 1% to protect the reflection of external light and ensure sufficient visibility, and to use this anti-glare film with high turbidity for notebook size. Personal computer, TV, etc. However, an anti-glare film having at least 10% high haze has the disadvantage that the contrast measured in a bright room is reduced due to its broad reflection-scattering properties. Furthermore, the anti-glare film having high turbidity also lowers the contrast measured in the dark room, which is also a disadvantage of the liquid crystal display. In order to solve those problems, JP-A-2006-5337 1 discloses that Low turbidity 200804919 (5) degree and anti-glare film of specific reflection mode, which forms irregularities on the honed metal plate of fine particles, electroless nickel plating on the non-surface of the metal plate to reduce irregularity The mold is formed in a depth, and the surface of the mold is irregularly transferred to the surface of the transparent resin film to produce > JP-A-2006-3 9270 describes the division of the surface thereof. The zone's anti-glare layer is applied to the display along with a linear polarizing film, a single-axis or a dual-axis retarder plate, to improve the VA-type liquid crystal display. SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid crystal display which has high anti-glare properties and improved viewing angle properties without improving the VA liquid crystal display. Another object of the present invention is to provide a laminate for a liquid crystal display anti-glare polarizing film. The liquid crystal display of the present invention is a VA type liquid crystal display unit sandwiched between a pair of polarizing plates and a retardation plate in one or two spaces between the liquid crystal cell substrate and the polarizing plate. An improved reflective anti-glare film disclosed in JP-A-2006-53 37 1 is applied to the liquid crystal display. Next, the anti-glare properties of the liquid crystal display are improved differently. As a result, a layer having a specific optical characteristic and a specific surface shape is provided on the screen side. That is, a pair of linear polarizing plates including the VA type liquid crystal and not only the front and back sides of the liquid crystal cell can be significantly improved. In the impact on the rules table and the specific field and the full double visible, the basis of the turbidity indicator, placed in the two-type resistance mode to enter the current anti-glare element, set a single -10 - 200804919 (6) Positive uniaxial or biaxial retardation plates between the meta-substrate and a linear polarizing film and between a unit substrate and a linear polarizing film or between other unit substrates and other linear polarizing films Two-axis blocker.

The reflectance R (30) of the reflection angle of 30 degrees or less of 30 degrees, the incident light entering the incident angle of 30 degrees has a reflectance R (40) of a reflection angle of 40 degrees of '0.003% or less, and 0. 001 or 60) the ratio of R(30), where R(> 60) ^ is the reflectance of incident light entering the incident angle of incidence at any angle of 60 degrees or more, and the prevention The surface of the glare layer is composed of a polygon having an average area of 50 μm 2 to 1,500 μm 2 , preferably 300 μm 2 to 1,00 0 μιη 2, wherein the polygons use the vertices of the irregular surface portion as the mother point and the Fino The surface formed by dividing the surface by (Voronoi) In the liquid crystal display of the present invention, the laminated board including the anti-glare layer, the linear polarizing film, and the retardation plate has a novel structure. Accordingly, the present invention also provides an anti-glare polarizing film laminate comprising an anti-glare layer, a linear polarizing film, and a retardation plate, which are laminated in this order, wherein the anti-glare layer has a normal incidence Turbidity of 5% or less of light, when using three kinds of optical frequency combs consisting of *dark and bright lines each having a width of 〇·5 mm, 1·0 mm, and 2·0 mm, respectively, at 45-degree light incidence The total reflection resolution when the angle is measured for reflection resolution is 50% or less, and the incident light entering at 30 degree angle of incidence has 2 °/. Or less than the reflectance of the 30 degree reflection angle R (30), for the incident angle of 30 degrees of incident angle has 0. The reflectance R ( 4 0 ) of the 003 % or smaller 40 ° reflection angle, and 〇 .  〇〇1 or smaller -12- 200804919 (8) R (k 60) to R ( 30) ratio, where R ( k 60) is the incident angle to the incident angle of 60 degrees or more Any reflectance, and the surface of the anti-glare layer is composed of a multi-turn having a uniform area of 50-μητ2 to 1,500, preferably 3〇0>m2 to 1:000μπι2. The polygons are irregularly convex. The apex of the portion is formed by dividing the surface by (Voronoi); and the retardation plate comprises at least one selected from the first retardation plate having the following relationship: nx > ny k nz and having the following relationship Refractive index: nx = ny > nz is a group of hysteresis plates, where nx and ny are the main refractive indices of the film plane, and nz is the refractive index in the direction of the degree, with the condition that when the first retardation plate is used It is placed such that the phase retardation axis of a retardation plate is substantially transmissive or substantially at right angles to the linear polarizing film. In the anti-glare polarizing film laminate of the present invention, the retardation plate is composed of a single first retardation plate having the following relationship: nx > ny k nz In the case where the retardation plate is placed such that its phase retardation The axis is substantially parallel or substantially at right angles to the transmission axis of the polarizing film. Alternatively, the resistance consists of a single second retardation plate having the following relationship: nx ^ ny Further, the retardation plate may be a stack of the first retardation plate and the second retardation plate. In this case, the laminate is advantageously placed such that the first plate faces the linear polarizing film, and the phase retarding axis of the first retarding plate is parallel or substantially perpendicular to the transmission axis of the linear polarizing film. .

Here, the linear retardation plate can be retarded by the ηζ 〇 layer plate group substantially - 13 - 200804919 Ο) In the anti-glare polarizing film laminate of the present invention, the anti-glare layer is advantageously made fine on the surface A regular resin film consisting of irregularities formed on a honed metal plate by bumping with fine particles, and nickel is electrolessly plated on the irregular surface of the metal plate to form a mold, The surface irregularity of the mold is transferred to the surface of the transparent resin film, and the resin film is removed from the mold. The liquid crystal display of the present invention has good anti-glare properties and also achieves a high contrast of φ and thus is superior to brightness and visibility of displayed images. The anti-glare polarizing film laminate of the present invention has low haze, but has fine irregularities on the surface to achieve the anti-glare property. Therefore, the anti-glare polarizing film laminate of the present invention can attain a high contrast ratio when it is applied to a liquid crystal display, particularly a VA type liquid crystal display. [Embodiment] The present invention will be described with reference to the accompanying drawings. Referring to Fig. 1, a liquid crystal display of the present invention comprises a liquid crystal cell 10, a pair of linear polarizing films 20, 21 sandwiching the liquid crystal cell 10, and a layer disposed between one of the linear polarizing films and the liquid crystal cell 10; The first retardation plate 26. The liquid crystal cell 10 includes a pair of unit substrates 1 1 and 1 2 and a liquid crystal layer 17 sandwiched between the unit substrates 1 1 and 1 2 and the unit substrates 1 1 and 1 2 have The surfaces thereof face the individual electrodes 14 and 15 of each other. In the liquid crystal layer 17 of the liquid crystal cell 10, liquid crystal molecules generally in the vicinity of the substrate from one substrate to the other substrate are oriented in a direction substantially perpendicular to the substrates when no voltage is applied. That is to say, the so-called vertical alignment (VA) type liquid crystal 200804919 (10) unit 10. The first retardation plate 26 has a refractive index satisfying the following relationship: nx > ny 2 nz, where nx and ny are the main refractive indices of the film plane, and nz is the refractive index in the thickness direction of the film. Here, the main refractive index in the plane of the film means the refractive index according to the direction of the maximum refractive index (phase-blocking axis direction) in the plane of the film and the refractive index in the direction perpendicular to the direction of the axis of the phase. In the long term, the direction of the refractive index is minimized (phase advance axis direction). The former is represented by h, while the latter is represented by ny. Therefore, the first blocking plate 26 is uniaxial (nx > ny = nz ) or biaxial (nx > ny > nz ). The first retarding plate 26 is placed such that its phase retarding axis is substantially parallel or substantially at right angles to the transmission axis of the adjacent linear polarizing film 20 or 21. Therefore, light leakage can be suppressed. Here, the phrase "substantially" in the phrase "substantially parallel to the axis" or "substantially right angle" means allowing a deviation of ±5 degrees from the parallel direction or the right angle direction, but ideally a completely parallel or precisely right angle. . In a preferred embodiment, the first retarder plate 26 is placed such that its phase retarding axis is substantially parallel to the transmission axis of the adjacent linear polarizing film. According to the present invention, the second retardation plate 27 is placed between the unit substrate with respect to the first retardation plate 26 and the linear polarizing film 21 or 20 on the side (Figs. 1A and 1B), or The unit substrate of the first retardation plate 26 is between the liquid crystal cell 10 (first C and FIG. 1D). The second retardation plate 27 has a refractive index satisfying the following relationship: nx = ny > nz, where nx, ny, and nz are the same as defined above. This means that the second retardation plate 27 is a film of an optical axis having a negative uniaxiality and a normal direction, or a c-plate. Here, "nx e ny " means that nx is exactly equal to ny, that is, the plane -15-200804919 (11) shown in the equation (1) has an internal block 値Ro of ο (zero), but in the plane The alignment can be virtually ignored, that is, the in-plane retardation 値 is within about 1 〇 nm, preferably within about -5 nm. Further, according to the present invention, the anti-glare layer 30 having a specific surface shape and imparting specific optical properties to the liquid crystal display is placed on the surface of the linear polarizing film 20 with respect to the surface facing the liquid crystal cell 10, that is, The surface on the display side (viewing side). The anti-glare layer has a shape φ above it, forming a large number of fine irregular anti-glare surfaces, and has a turbidity of 5% or less for normal incident light, and each has 0. 5 mm, 1. 0 mm and 2. The three kinds of optical frequency combs composed of dark lines and bright lines of 0 mm width have a total reflection resolution of 50% or less when measuring the reflection resolution at a 45-degree light incident angle, and have two incident light incidents at an incident angle of 30 degrees. The reflectance R(30) of the reflection angle of 30% or less, and the incident light entering the incident angle of 30 degrees have a reflectivity R(40) of 反射·〇〇3% or less of a reflection angle of 40 degrees, And 0. Ratio of R ( 2 60 ) to R ( 30 ) of 001 or less, where R ( φ > 60) is the reflectance of incident light entering the incident angle of 30 degrees at any angle of 60 degrees or more. The surface of the anti-glare layer is composed of a polygon having an average area of 50 μm to 1,500 μm, preferably 300 μπ 2 to 1, 〇〇〇μπι 2, wherein the polygons use the vertices of the irregular surface portion as the mother The point is formed by dividing the surface. This anti-glare layer will be described in detail below. In FIG. 1, when the anti-glare layer 30 and the display-side linear polarizing film 20 and the retardation plates 26 and/or 27 are provided in the liquid crystal cell 10 When not on the side, the anti-glare layer 30, the display side-16-200804919 (12) linear polarizing film 20 and the laminated plates of the retardation plates 26 and/or 27 are shown as the anti-glare polarizing film stack Laminate 40 or 41. When the linear polarizing film 21 and the retardation plate 26 and/or 27 are provided on the back side of the liquid crystal cell 1', the stack of the linear polarizing film 21 and the retardation plate 26 and/or 27 is shown as * Back side anti-glare polarizing film laminate 50. - the anti-glare polarizing film laminate 40 or 41 and the liquid crystal cell 1 and the back side polarizing film 21 or the back side anti-glare polarizing film laminate 50 and φ. The liquid crystal cell 1 〇 usually uses an adhesive 60 to stick. As the adhesive, those having good transparency such as an acrylic adhesive are generally used. In general, a backlight 70 is provided on the back side of the back side polarizing film 21 to supply light to the liquid crystal cell. The linear polarizing film 20, 21 may be a linearly polarized light that allows one of the two directions perpendicular to each other in the plane of the film to oscillate, while the other will absorb the linear polarization oscillating according to the other of the two directions. A commonly used polarizing film or plate for light. A designated example of this linearly polarized light is a uniaxially stretched polyvinyl alcohol φ film which is dyed with a high dichroic dye and crosslinked with boric acid. A polarizing film containing iodine as a base of a high coloring dye or a dye as a base containing an organic dichroic dye serving as a high dichroic dye may be used. The linear polarizing film may be a polyvinyl alcohol type polarizing film of this type or a polyvinyl alcohol type polarizing film having a transparent polymer protective film having, for example, triethyl fluorenyl cellulose or the like on its surface. Since the anti-glare layer 30 is provided on one surface of the display-side linear polarizing film 20, it can serve as a protective film for the display-side linear polarizing film 20. When the retardation plate 26 or 27 is provided on the other surface of the display-side linear polarizing film 20-17-200804919 (13), it can serve as a protective film for the display-side linear polarizing film 20. When the anti-glare layer 30 is provided on one surface of the surface-side linear polarizing film 20, and the other surface of the surface-arc linear polarizing film 20 is directly adhered to the surface by the adhesive 60 as shown in FIG. 1D When the liquid crystal cell 1 〇 ', a protective film as described above is provided on at least the surface * of the linear polarizing film 20 with respect to the anti-glare layer 30. When the retardation plate 26 or 27 is provided on the surface of one of the back side polarizing films 21 as shown in Figs. 1B and 1D, it can serve as a protective film for the linear polarizing film 21. In this case, a protective film as described above is preferably provided on the other surface of the linear polarizing film 21. When no laminated layer such as the retardation plate is on the back side polarizing film 21, a protective film as described above is provided on both surfaces of the linear polarizing film 21. The first retardation plate 26 has a refractive index satisfying the following relationship: n χ > n y 2 η z ' wherein n X, n y and η z are in agreement with the above. The in-plane retardation 値Ro is selected from the range of 30 to 300 nm, depending on the characteristics of the liquid crystal cell, and the like. Preferably, the ratio of R 〇 to Rth exceeds 1 but does not exceed 2. The retardation plate having this characteristic can be produced by uniaxially or biaxially stretching a transparent resin film having a positive anisotropic refractive index under appropriate conditions. Examples of the transparent resin film having a positive anisotropic refractive index include acrylated cellulose, cyclic olefin resin, polycarbonate, and the like, such as triethylene fluorene fiber. The cyclic olefin resin is a resin containing a cyclic olefin in the form of a monomer such as norbornene, dimethyl octahydronaphthalene or the like. Commercially available examples of cyclic olefin polymers are ARTON (registered trademark) (available from JSR Ltd.), ZEONOR® and ZEONEX® (both available from -18-200804919 (14) ΖΕΟΝ) Wait. Among these transparent resins, triethyl fluorenyl cellulose and cyclic olefin resins are preferably used because they have a low light transmittance coefficient and thermal strain will cause small in-plane characteristics to deteriorate under the use conditions. The retardation plate 27 has a refractive index that satisfies the following relationship: heart ny > nz, where nx, ny, and nz are the same as defined above. This retardation can be carried out by applying a discotic liquid crystal on the substrate, coating a liquid crystal of the cholesterol phase on the base φ at a narrow interval, and forming a layer of an organic layer-forming compound such as mica on the substrate. Or continuous biaxial stretching of the resin film is achieved by providing an unstretched solvent-formed film. The second retardation plate preferably has an R 0 of 0 to 10 nm and an Rth of 50 to 300 nm. The material of the retardation plate 27 or the substrate material of the retardation plate 27 is not limited. Preferably, the retardation plate 27 has a layer which can be arbitrarily formed and which is layered with a low-cost control layer at a low cost. Examples of commercially available retardation plates having such retardation include "VAC film" (registered trademark) ^ available from Sumitomo Co., Ltd., "FUJITAC film" (trademark) (available from FUJIFILM Co., Ltd.) )and many more. Since the two retardation plates 27 have an index of refraction relationship of nx = ny and thus about 〇 (R 〇 of zero, it is not necessary to define the axis angle of the phase retardation axis, that is, the use of a very small RQ is also the same. A specific example of the liquid crystal display shown in FIG. 1A includes a liquid crystal cell, an anti-glare polarizing film laminate 40 on one surface (display side surface) of the liquid crystal cell 1 and a liquid crystal cell The back side anti-glare polarizing film laminate 50 on the front surface (back surface).

The difference between the specific example of FIG. 1A and the specific example of FIG. 1B is the same. The position of the retardation plate 26 is opposite to that of the second retardation plate 27. φ The specific example of the liquid crystal display shown in Fig. 1C includes the liquid crystal cell 1 〇, and anti-glare on one surface (display side surface) of the liquid crystal cell a polarizing film laminate 40 and a linear polarizing film 21 on the other surface (back side) of the liquid crystal cell 1.

In the specific example of FIG. 1C, the laminated plate of the linear polarizing film 20, the first retardation plate 26, and the second retardation plate 27 is provided on the display surface φ side of the liquid crystal cell 10, and The anti-glare layer 30 is provided on the linear polarizing film 20, however, in the first D diagram, the second retardation plate 27, the first retardation plate 26, and the linear polarization are provided on the display surface side of the liquid crystal cell 10 a laminated plate of the film 2 1 and not providing a retardation plate on the display surface side of the liquid crystal cell 1 〇 in the anti-glare polarizing film laminated plate of the present invention, according to the first A, 1 B and 1 C The anti-glare layer 30, the linear polarizing film 20, and the retardation plates 26 and/or 27 are laminated in the order shown. The cross-section of the anti-glare polarizing film laminate 40 alone is schematically shown in Fig. 2, wherein the retarding plate 25 represents the first retarding plate 26 and/or the second retarding plate 27. That is, the retardation plate 25 may be a retardation plate having a refractive index satisfying the following relationship: nx > ny 2 nz (i.e., the above first 'blocking plate), or a refractive index satisfying the following relationship: χ χ ny ny > nz (i.e., the second retardation plate described above), wherein nx, ny, and nz are the same as defined above, or, as shown in Fig. 3, the laminate has a refractive index satisfying the following relationship: nx > ny k The first retardation plate 26 of nz (i.e., the first retardation plate described above) and the-21-200804919 (17) have a refractive index that satisfies the following relationship: nx e ny > nz the second retardation plate. In this embodiment, the first retardation plate 26 is placed so as to face the linear polarizing film 20 and its phase retarding axis is substantially parallel or substantially at right angles to the transmission axis of the linear polarizing film 20. The anti-glare layer 3 has a turbidity of 5% or less for normal incident light ‘, and each has 0. 5 mm, 1 · 0 mm and 2. The three kinds of optical frequency combs composed of dark and bright lines of 0 mm width measure the total reflection resolution of φ reflection resolution at 50 degrees of light incident angle of 50% or less, and the incident light entering for 30 degree angle of incidence has 2 The reflectance R ( 30 ) of the reflection angle of 30% or less, and the incident light entering the incident angle of 30 degrees has 0. The reflectance R ( 40 ) of the reflection angle of 40 degrees or less of 003% or less, and 0. Ratio of R(2 60) to R(3 0) of 001 or less, where R(2 60) is the reflectance of incident light entering a 30 degree angle of incidence in any direction of a reflection angle of 60 degrees or more, And the surface of the anti-glare layer 30 is composed of a polygon having an average area of 50 μm to 1,500 μm, preferably 300 μπ 2 to φ 1, 〇〇〇μπι 2, wherein the polygons are irregularly convex portions. The vertex is used as the parent point and the voucher is formed by dividing the surface. Now, the anti-glare layer 30 will be described in detail. The anti-glare layer 3 is preferably manufactured by the method described below, and has an anti-glare surface on which fine irregularities are formed, and a haze of 5% or less for the normally incident light. Although the anti-glare layer 30 has fine irregularities on the surface, when it is applied to a liquid crystal display, it will have low haze and thus it can suppress a decrease in contrast. The anti-glare layer 30 has a total reflection resolution of -22-200804919 (18) for 50% or less of incident light of 45 degrees. The reflection resolution can be measured by the method described by ns K 7105. In the method of Jis Κ 7105, it is defined and used to have 0. 1 2 5 m m, 0. 5 m m, 1. Four optical frequency combs consisting of a dark line of 0 m m and 2 · 0 m m and a bright line (the ratio of the width of the dark line to the width of the bright line is 1:1). In the present invention, in the reflection clarity measured using four kinds of optical frequency combs, it is not used to have 0. The obtained light-frequency comb of a width of 125 mm is added to the sum because the reflection resolution obtained by the φ optical frequency comb is too small to use the anti-glare film according to the present invention, so that the measurement enthalpy has a large error. Thus, in the present invention, the total reflection resolution is used by each having 0 · 5 mm, 1.0 mm and 2. The sum of the reflection resolutions measured by the three optical frequency combs consisting of a dark line and a bright line of 0 mm width. Thus, the maximum possible 値 of the total reflection resolution according to the above definition is 300%. When the total reflection resolution exceeds 50%, an image such as a light source image or the like is reflected so that the anti-glare property of the anti-glare polarizing film laminate of the present invention is deteriorated. When the total reflection resolution is 50% or less, it may be difficult to evaluate the superiority of the anti-glare property only from the φ total reflection resolution, because if the total reflection resolution is 50% or less, use Has 0. 5 mm, 1. The three types of optical frequency combs of 0 mm and 2·0 mm width have a respective reflection clarity of at most about 10 to 20%, so the reflection sharpness fluctuation caused by the measurement error cannot be ignored. Next, the dependence of the reflectance on the reflection angle will be described with reference to Figs. 4 and 5 as another criterion for evaluating the anti-glare property. Figure 4 is a perspective view showing the direction of light incident and the direction of reflection associated with the anti-glare layer (anti-glare film). According to the present invention, when R(30) is defined as incident light 36 entering at a 30 degree angle from the normal 35 of the anti-glare layer 30, relative to -23-200804919 (19), according to a 30 degree reflection angle The reflectance of the reflected light of the direction, that is, the reflection direction 37, is R (30) of 2% or less. The reflectance R ( 30 ) is preferably 1. 5% or less, more preferably 0. 7% or less. When the reflectance R ' (30) exceeds 2%, the anti-glare layer may not have sufficient anti-glare properties such that the visibility of the display is lowered. In Fig. 4, the direction of the reflected light at any corner 以 is indicated by the number 3 8 , and the directions 37 and 38 of the φ reflected light are present in the direction 36 including the incident light and the film in the reflectance measurement. The normal 3 5 plane is 3 9 in. Figure 5 is a graph depicting the reflectance of reflected light 18 associated with incident light 36 entering at an angle of 3 5 3 0 from the anti-glare layer 3 0 of the anti-glare layer of Figure 4 (where the coordinate axis is by logarithmic scale) An embodiment of a graphic representation. A graph showing the relationship between the reflectance and the reflection angle, or a reflectance read from the pattern of the respective reflection angles is called a "reflection mode". As shown in Fig. 5, the reflectance R (3 〇) is a reflectance peak 有关 related to the incident light 36 φ entering at an angle of 30 degrees, and the reflectance tends to decrease as the reflection direction deviates from the reflection direction. According to the present invention, when R ( 40 ) is defined as incident light 3 6 ' ' at a angle of 30 degrees from the normal line 35 of the anti-glare layer 30 shown in Fig. 4, the angle of reflection is 40 degrees. The reflected light reflectance of the direction is R ( 4 0 ) of 0 · 0 0 3 % or less. When R ( 4 0 ) exceeds 〇 · 〇 〇 3 %, the displayed image tends to whiten. Thus, R ( 4 〇 ) is preferably not so large. When R ( 40 ) is too small, the anti-glare layer may not have sufficient anti-glare properties. Therefore, R(40) is preferably at least 0. 00005%. However, it is quite difficult to closely determine the range of R (40) -24-200804919 (20) because reflection or change of white is subjectively determined by the eye and the characteristics reflecting the user's preference. Furthermore, according to the invention, the ratio of R ( ^ 60 ) to R ( 30 ) is 0. 001 or less, where R(k 60) is the reflectance in any direction of the reflection angle of 60 degrees or more. This ratio is preferably 0. 0005 or smaller, better - ground 0. 000 1 or less. Here, "any direction of the reflection angle of 60 degrees or more" means a reflection angle of a range between 60 degrees and 90 degrees. The anti-glare film manufactured by the method described in the following φ has the typical mode shown in FIG. 5, and in the case of the anti-glare film, the reflectance often has a peak according to the reflection direction and increases with the reflection angle. Gradually decreases. Therefore, the ratio of R(2 60) / R(30) can be expressed by R(60) / R(30), where R(60) is the reflectance at a reflection angle of 60 degrees. When the ratio of R(>60)/R(30) exceeds 0. At 0 01, the anti-glare layer will see white and the visibility of the display will deteriorate. That is to say, when a black image is displayed on the display screen and the anti-glare layer is provided in front of the screen, the entire screen will see white reflecting the light outside the φ light. In the case of the reflection mode shown in Fig. 5, the reflectance R ( 30 ) is about 0. 4%, R ( 40 ) is about 0. 0006%, and R ( 60 ) is about 0. 00 0 03%. In addition to the specific reflection mode described above, the surface of the anti-glare layer according to the present invention is composed of polygons having an average area of from 50 μχη 2 to 1,500 μπ 2 , preferably from 300 μm 2 to 1,000 μπ 2 , wherein the polygons The vertices of the irregularly convex portion are used as the mother point and the voluminous is formed by dividing the surface. -25- 200804919 (21) A deductive method for measuring the apex of the convex portion of the irregular surface of the anti-glare layer will be described. When attention is focused on an arbitrary point on the surface of the anti-glare layer, if there is no higher height around the arbitrary point than the arbitrary point, and the height of any point on the irregular surface is higher than the highest on the irregular surface When the middle 之间 between the height of the point and the height of the lowest point is higher, the arbitrary point is the apex of the convex portion. Specifically, as shown in Fig. 6, as shown in Fig. 6, an arbitrary point 91 is selected on the surface of the anti-glare layer. Using this point 91, a circle having a radius of 2 μm to 5 μm is drawn when φ is the center of a circle in a plane parallel to the base plane 93 of the anti-glare layer. When there is no point higher than the height of the point 9 1 in the circle 9 4 projected on the surface 93 of the anti-glare layer, and the height of the point 9 1 is higher than the highest point height on the irregular surface When the middle 値 height between the lowest point heights is determined, the point 9 1 is determined as the apex of the convex portion. In this case, the projected circle 94 has a radius that does not account for minute irregularities on the surface of the sample, and the circle 94 does not include a plurality of convex portions. Thus, the radius of the circle 94 is preferably about 3 μm. Through the above method of φ, it is also possible to count the convex surface fraction per unit area of the irregular surface. In order to achieve good visibility without causing reflection or whitening, the number of convex portions counted by the above method is preferably 50 to 150 in the field of view of 200 μπι 200 μηι. If the number of convex portions on the irregular surface of the anti-glare layer is small, the pixel may cause glare to make the displayed image difficult to look at, especially when the anti-glare polarizing film laminate and the display device having high definition When used together. Furthermore, the texture of the displayed image will deteriorate. When the number of convex portions is too large, the inclination angle of the irregular shape becomes very -26-200804919 (22) so steep that the image tends to become white. The number of convex portions in the field of view of 200 μm 2 2 μm is preferably 120 or less and 7 or more. Now 'will explain the Fino to split. When a number of points (ie, 'mother points') are scattered on a plane, which can be segmented by determining the closest parent point of any point on the plane, the pattern is Funuo, and via this graphic Planar segmentation is called Fu Nuo to segment. Fig. 7 is a view showing a divisional embodiment in which the apex of the convex portion on the surface is used as a mother point and the surface of the anti-glare layer is divided by φ vomin. In Fig. 7, the point 95 is a mother point, and the respective polygons 96 including one mother face are the regions formed by the segmentation by the Fino, and the polygon is referred to as the Frono region or the Frono polygon. And later referred to as Fu Nuo as a polygon. The area 97 darkened around Fig. 7 will be described later. In the figure, the number of mother points is equal to the number of polygons. Briefly, in Fig. 7, numbers 95 and 96 refer to not a part of the mother point and a part of the polygon, respectively. It is necessary to calculate the average area of the nucleus obtained by dividing the vertices using the convex portions as the mother points by the voicing φ, using a suitable device such as a confocal microscope, an interference microscope, an atomic force microscope (AFM), or the like. The surface shape of the anti-glare layer was observed, and the three-dimensional coordinate 値 was measured. Next, according to the following deduction method, Fu Nuo is used to divide the surface of the anti-glare layer, and the average area of the polygon is calculated. That is, the irregular surface of the anti-glare layer is determined according to the above deductive method, and then the apex of the convex portion is projected on the base surface of the anti-glare layer. Thereafter, all three-dimensional coordinates obtained by surface shape measurement are projected on the plane of the base, and all projection points are assigned to the closest mother face to perform the segmentation. Calculate all -27- 200804919 (23) Fu Nuo is the area of the polygon and averaged to obtain the average area of the Fu Nuo polygon. In this measurement, the Frox of the boundary of the adjacent measurement field is not counted in the polygon area to minimize the error. That is to say, in the case of Fig. 7, the calculation of the average area does not include the measurement of the darkening of the vicinity of the boundary of the visual field by the polygon 97. In addition, in order to minimize measurement errors.  Preferably, the Fouro's average 値' of the polygons is calculated in at least three fields of view each having a field of view of 200 μηη 200 μπι and then all the average 値 φ are evenly averaged and measured as 値. As described above, in the present invention, the average area of the undox of the convex portion having the irregular surface on the irregular surface of the anti-glare layer serving as the mother point is from 50 μm 2 to 1,500 μm 2 , preferably 300 μπ 2 . To 1,000 μπι2. When the average area of the undox is less than 5 〇 μπι 2, the irregular shape of the surface of the anti-glare layer becomes steep so that the image becomes white. When the average area of the undone is more than 1,5 〇〇μπι 2, the irregular surface of the anti-glare layer will become rough, so that glare is generated and the texture φ of the image is deteriorated, particularly when the anti-glare polarizing film The laminate is used in conjunction with a high-definition display device. Using the three-dimensional coordinates measured here, the arithmetic mean height Pa of the section curve and the maximum section strength Pt (which is defined by JIS 060 060 1 (=ISO * 4287)) can be calculated. Furthermore, the respective point heights on the irregular surface of the anti-glare layer can be described in a rectangular pattern. In order to achieve good visibility without causing reflection or whitening, the arithmetic mean height Pa of the cross-sectional curve is preferably 0. 08 μπι to 0. 15 μπι, and the maximum cross-sectional height Pt is preferably from 0·4 μηη to 0·9 μπι. When the arithmetic mean height Pa is less than 0. 08 μπι -28-200804919 (24) The surface of the anti-glare layer is substantially flat so that it has no anti-glare properties. When the arithmetic mean height Pa exceeds 0. At 15 μη, the surface shape of the anti-glare layer becomes rough, causing problems such as whitening and glare. When the maximum section height Pt is less than 0. At 4 μηι, the surface of the anti-glare layer is again substantially flattened so that it has no anti-glare properties. When the maximum sectional height Pt exceeds 0·9 μm, the surface shape of the anti-glare layer becomes rough again, causing problems such as whitening and glare. When the height of a dot on the irregular surface of the anti-glare layer is described in a rectangular diagram, the peak of the histogram preferably has a highest point height (100% height) and a lowest point height (0%) on the irregular surface. The middle 値 (50% height) between the heights is within ±20%. This means that the peak of the histogram is preferably in the range of between 30% and 70% of the height difference between the highest point height and the lowest point height. If the peak does not exist within ±20% of the intermediate crucible, in other words, the peak has a height greater than 70% or less than 30% of the height of the highest point, the surface shape of the anti-glare layer will become rough. As a result, glare tends to occur undesirably. In addition, the texture tends to deteriorate. In order to describe the rectangular map of the heights, the highest and lowest points on the surface of the anti-glare layer (anti-glare film) are measured, and then the difference between the height of the respective measurement point and the height of the lowest point (ie, the height of the measurement point) is divided by the highest point. The difference between the height and the lowest point height (ie, the maximum height difference) is obtained to obtain the relative degree of each point. The receiver's use the rectangular map with the most local degree of 1 〇 〇 % and the lowest height 〇 % to describe the relative heights obtained to obtain the peak positions of the respective points in the histogram. The histogram should be divided into segments to avoid the effects of data errors, and in general it is divided into approximately 10 to about 30 segments. For example, the interval from the lowest point (〇% height) to the highest point (100% height) is divided by 5 % -29-200804919 (25), and the position of the peak is determined. The anti-glare surface constituting the anti-glare layer having the above characteristics has a shape covered by an irregular condition in which there is no flat plane. An anti-glare surface having such a surface shape may advantageously form irregularities on the honed metal sheet by impacting with fine particles, and electroless nickel is formed on the irregular surface of the metal sheet to form a mold 'the surface of the mold Irregular conditions are transferred to the surface of the transparent resin film, and a transparent resin film having a transfer irregularity is removed from the mold. A preferred method for producing an anti-glare layer (anti-glare film) by the above method is described with reference to Fig. 8, which schematically shows that the irregularity of the mold is transferred to the resin film using a metal plate as a mold body. A cross-sectional view of the step of having an irregular mold on its surface. Figure 8A shows a section of the metal plate 81 after mirror honing with a honed surface 82. Irregularities are formed on the surface 82 by impinging (or blowing) the honed surface 82 of the metal plate 8 1 with fine particles. Fig. 8B is a view schematically showing a section of the metal plate 81 after the impact, which has a hemispherical fine concave portion 83. Next, the irregular surface formed by the impact is electrolessly plated with nickel to reduce the irregular depth. Fig. 8C schematically shows the cross section of the metal plate 81 after electroless plating of nickel. In Fig. 8C, a nickel plating layer 84 is formed on the surface of the metal plate 81 having a fine concave portion, and the surface 86 of the nickel plating layer 84 has irregularities which are electrolessly plated with nickel compared to the figure. The concave surface 83 has a reduced depth; that is, the irregular shape of the surface of the metal plate is made dull. Thus, when the metal concave portion 83 having the hemispherical shape of the metal -30-200804919 (26) plate 81 is electrolessly plated with nickel, substantially no flat plane can be obtained and it is suitable for fabricating a preferred optical property. A mold for the irregularity of the anti-glare film. Fig. 8D schematically shows the step of transferring the mold irregularity of the 8Cth image formed in the previous step to the resin film. That is, a resin film is formed on the irregular surface of the nickel plating layer '84. Thereby, a film 30 having a transferred irregular shape is obtained. The film 30 may be composed of a single thermoplastic transparent resin film φ. In this case, the thermoplastic resin film in a heated state is pressed to the irregular surface 86 of the mold and formed by hot press. Alternatively, as shown in Fig. 8D, the film 30 may be composed of a transparent substrate film 32 and an ion-radiation-curable resin layer 33 laminated on the surface of the substrate film 32. In this case, the ionizable radiation-curable resin layer 3 3 is brought into contact with the irregular surface 86 of the mold and irradiated by ionizing radiation to cure the resin layer 33. Thereby, the irregular shape of the mold is transferred to the ionizable radiation-curable resin layer 33. These films will be described later. Fig. 8E is a schematic cross-sectional view showing the film 30 after being removed from the φ mold. In the method shown in Fig. 8, preferred examples of the metal used for the manufacture of the mold include aluminum, iron, copper, stainless steel, and the like. Among them, it is preferable that the metal is easily deformed by the impact of fine particles, that is, it is not too high. In particular, it is preferred to use aluminum, iron, copper or the like. From the standpoint of cost, aluminum and soft iron are more preferred. The mold may be in the form of a flat metal plate or a cylindrical metal roll. When a roll mold is used, the anti-glare film can be continuously produced. The fine particles are used to strike or blow the metal having the honed surface. -31 - 200804919 (27) In particular, the metal is preferably honed to a near-mirror state because the metal plate or roll is often machined to achieve the desired precision by, for example, cutting or honing. Degree, and the processing marks are often left on the surface of the metal body. If a deep mark is left, the surface of the metal body may have trace marks after the impact of the fine particles, because the depth ratio of some marks is larger than the irregular depth formed by the fine particles, so that the trace amount is deep. The mark may have an unexpected effect on the optical properties of the anti-glare layer. φ The method for honing the metal surface is not limited, and any of mechanical honing, electrolytic honing, and chemical honing can be used. Examples of the mechanical honing include a superfinishing method, a fine boring method, a fluid honing method, a buffing wheel honing method, and the like. In view of the center line average roughness Ra, the surface roughness after honing is 1 micrometer or less, preferably 0. 5 micrometers or less, more preferably 0. 1 micron or less. When R a is too large, the influence of the surface roughness before deformation may still be after the deformation of the metal surface by the impact of the fine particles. The lower limit of Ra may not be limited, but may be limited from the viewpoint of processing φ time, processing cost, and the like. The method of striking the metal surface with fine particles is preferably a blowing treatment. Examples of the blowing method include a sandblasting method, a spray method, a liquid honing method, and the like. Regarding the particles used in these treatments, those having a shape close to a sphere are better than those having a sharp edge. Furthermore, the particles of the hard material are preferred because they do not break when processed to form sharp edges. Preferred examples of the ceramic ceramic particles satisfying those properties are spherical oxidized particles, alumina particles and the like. Examples of preferred metal particles are steel, stainless steel, and the like. Further, it is possible to use a particle comprising particles of ceramic or gold-32-200804919 (28) granules on a resin binder. When particles having an average particle size of 10 to 75 μm, preferably 10 to 35 μm, in particular, spherical fine particles are used as fine particles impinging on the metal surface, an anti-glare film can be produced which satisfies A shape factor according to the present invention, defined in the range of 50 μπι to 1,500 μπ 2 , preferably from 3 0 0 μπι 2 to 1,000 μπι 2 , in terms of the average area of the polygon. Regarding such fine particles, those having a uniform particle size, that is, φ are particularly preferably a single particle. When the average particle size of the fine particles is too small, it will be difficult to satisfy the irregularities on the surface of the metal. In addition, the tendency angle of the irregular shape becomes so steep that the image tends to become white. When the fine particles are too large, the surface irregularities become rough so that glare may occur, and the texture of the image may be deteriorated. The irregular metal surface formed by the above method is then electrolessly plated with nickel to reduce the irregular depth. The degree of depth reduction depends on the type of metal, the irregular size and depth of the blown film, the type and thickness of the nickel plated, and the like. The most important factor controlling the degree of depth reduction can be the thickness of the nickel plated. If the thickness of the electroless nickel is too small, the irregular depth formed by the blowing or the like may not be effectively reduced, so that the optical properties of the irregular anti-glare film transferred from the mold may not be sufficiently improved. When the thickness of the electroless nickel is too large, productivity will decrease. Accordingly, the thickness of the electroless nickel is preferably from about 3 to 70 μm, more preferably at least 5 μm and 50 μm or less. In order to form an plating layer on the metal surface, it is preferred to use an electroless plate which can form a plating layer having a macroscopic uniform thickness on the metal plate or roll, -33-200804919 (29), in particular, providing high The hardness of the plated layer is electroless nickel plated. Preferred examples of the electroless nickel plating include gloss nickel plating using a plating bath containing a gloss agent such as sulfur or a nickel-phosphorus alloy plating (low phosphorus type, medium phosphorus type or high phosphorus type), and nickel- Boron alloy plating and so on. If the hard chrome plating described in JP-A-2〇02-189106 is used, especially ', electrolytic chrome plating, the electric field tends to concentrate on the edge of the metal plate or roll so that the thickness of the plated metal at the center and the edge may be different. . Therefore, if irregularities having a uniform depth are formed on the entire surface of the metal plate or the roller by blowing φ or the like, the degree of reduction in plating depth may vary depending on the position on the entire surface of the metal plate or the roller. As a result, these irregular depth changes. Therefore, electrolytic plating is not suitable for use in the present invention. Further, the hard chrome is plated with a mold which can form a rough surface and is thus unsuitable for use in the manufacture of the anti-glare layer. To remove the rough surface, the hard chrome plated surface is typically honed. However, the honing of the plated surface as explained below is not suitable for use in the present invention. # However, the present invention does not include forming a thin chrome plating on the outermost surface after the electroless nickel plating, that is, so-called flash chrome plating to provide surface hardness. If flash chrome plating is performed, the thickness of the flash chrome layer is as small as possible to avoid deterioration of the shape of the electroless nickel layer serving as the underlayer, and preferably should be 3 μm or less, more preferably 1 μm or less. Further, in the present invention, it is not preferable to honing the metal plate or the roll after plating in a manner as disclosed in JP-A-2004-90 1 87. If the plated surface is honed, the outermost surface may have a flat portion such that the optical properties of the anti-glare layer may be deteriorated' and the irregular shape is hardly controlled by good productivity - 34-200804919 (30), Because the number of control factors formed will increase. Fig. 9 schematically shows a metal plate on which a flat surface is formed by honing an irregular surface formed by impact of fine particles, which irregularities have been reduced by electroless nickel plating. That is, Fig. 9 corresponds to an electroless plated metal plate of Fig. 8C in which the surface of the nickel plating layer 84' is honed. As a result of the honing, a portion of the convex portion of the surface irregularity 86 formed on the nickel-plated layer 84 on the metal plate 81 is honed and thereby forms the flat plane 29. φ According to the present invention, an irregular mold having a surface formed on the surface thereof as shown in Fig. 8C is used, and the irregular shapes are transferred to the surface of the film 30 to form an anti-glare surface. In this case, the surface shape of the mold can be transferred to the surface of the film by any conventional method. For example, a thermoplastic resin film is hot pressed to the irregular surface 86 of the mold to irregularly transfer the surface of the mold to the surface of the resin film; an ion-radiation-curable resin is coated on the surface of the transparent resin film, and then The ion-radiation-curable resin coating in an uncured state is tightly adhered to the irregular surface of the mold and is irradiated with ionizing radiation to cure the ion-radiable resin through the transparent resin film. The surface of the mold was irregularly transferred to the surface of the cured ion-radiation curable resin. After the transfer, the film was removed from the mold as shown in Fig. 8E to obtain the anti-glare film 30. The latter method of using an ionizable radiation-curable resin is preferred from the viewpoint of, for example, prevention of mechanical strength such as surface cracks. The transparent resin used in the latter method described above may be any film having substantial light transparency. Specific examples of the transparent resin include cellulose resins (e.g., triethylenesulfonyl cellulose, diethyl cellulose, cellulose acetate propionate-35-200804919 (31) ester, etc.), cycloolefin polymer, poly Carbonate, polymethyl methacrylate, polyfluorene, polyether oxime, polyvinyl chloride, and the like. The cycloolefin polymer is a cyclic olefin comprising, for example, norbornene, dimethyl octahydronaphthalene or the like as a monomer. Examples of commercially available cyclic olefin polymers are ARTON (registered trademark) (available from JSR Co., Ltd.), ZEONOR® and ^ ZEONEX® (both available from ΖΕΟΝ ΖΕΟΝ). Among them, a thermoplastic transparent resin film such as polymethyl methacrylate, polycarboate, polyfluorene, and polyether oxime and cycloolefin polymer is pressure-bonded or pressure-bonded to have a surface at an appropriate temperature. An irregular mold is then peeled from the mold to irregularly transfer the surface of the mold to the surface of the film. Further, a polarizing plate is used as the transparent film and the surface irregularity of the mold can be directly transferred to the surface of the polarizing plate. When the ion-radiation-curable resin is used to transfer the surface irregularities of the mold, it is preferred to use a polymer having at least one propylene group-containing compound in the molecule. In order to increase the mechanical strength of the anti-glare layer, it is more preferred to use an acrylate having at least three functional groups, that is, a compound having at least three acryloxy groups. Specific examples of the compound include trimethylolpropane triacrylate, trimethylolethane triacrylate, glycerol triacrylate, pentaerythritol triacrylate, pentaerythritol tetraacrylate, dipentaerythritol hexaacrylate, and the like. In order to impart flexibility to the anti-glare layer in order to prevent the anti-glare layer from being broken, it is preferred to use an acrylic compound having an urethane bond in the molecule. A designated example of the acrylic compound is two compound molecules having at least one hydroxyl group in addition to the acryloxy group in the molecule (for example, trimethylolpropane triacrylate, pentaerythritol tripropylene-36 - 200804919 (32) acid ester, etc. And so on) added to a diisocyanate compound (for example, hexamethylene diisocyanate, toluene diisocyanate, etc.). Further, other acrylic resins which are radically polymerized and cured via ionizing radiation, such as an ether acrylate polymer, an ester acrylate polymer and the like, may be used. Further, a cationically polymerizable ion-radiation-curable resin such as an epoxy resin, an oxetane resin or the like can be used as the resin imparted to the irregularity after curing. In this case, an example of the cationically polymerizable ion-radiation-curable resin may be, for example, from 1,4-bis[(3-ethyl-3-oxetanylmethoxy)methyl]benzene. a cationically polymerizable polyfunctional oxetane compound such as bis[(3-ethyl-3-oxetanylmethoxy)methyl]ether or the like, and, for example, hexafluorophosphate (4-A) A cationic photopolymerization initiator of phenyl)[4-(2-methylpropyl)phenyl]anthracene or the like is prepared. When the ionizable radiation-curable acrylic resin is cured by irradiation with UV rays, a UV radical polymerization initiator which generates radicals by irradiation of UV rays to initiate polymerization and curing reaction is used. The UV rays are usually irradiated from the side of the glass mold or the transparent resin film. Thus, when UV rays are irradiated from the side of the transparent resin film, a polymerization initiator which initiates a radical generating reaction in the visible light to UV ray range is used to induce freedom in the wavelength range of UV rays through which the light can pass through the film. The base generates a reaction. Examples of the UV ray radical polymerization initiator which initiates the radical generating reaction by irradiation with UV rays include 1-hydroxycyclopropyl phenyl ketone, 2-methyl-1-[4-(methylthio)phenyl] -2-morpholinylpropan-1-one, 2-hydroxy-2-methyl-1-phenylpropan-1-one, and the like. When the UV ray is irradiated through a transparent resin film containing a UV ray absorbing agent, a radical photopolymerization initiator having an absorption range of -37 to 200804919 (33) in the visible light wavelength range is used. Examples of the initiator include bis(2,4,6-trimethylbenzylidene)phenylphosphine oxide, bis(2,6-dimethoxybenzylidene)-2,4,4 oxidized. - Trimethylphenylphosphine, 2,4,6-trimethylbenzimidyl diphenylphosphine, and the like. ^ When the mold is in the form of a flat plate having a fine irregular irregular plating surface, the irregular surface of the mold can be combined with the transparent resin coated with the uncured ion-radiation-curable resin The layer contact of the film causes the coating of the φ ion-radiation-curable resin to adhere tightly to the irregular surface of the mold, followed by irradiation of ionizing radiation from the side of the transparent resin film to cure the ion-radiation-curable resin. Thereafter, the cured layer of the ionizable radiation-curable resin and the transparent resin substrate film are removed from the mold. Thereby, the irregular shape of the mold is transferred to the ionizable radiation-curable resin cured layer carried on the transparent resin film. When the mold is in the form of a roll having a fine irregular plating surface on its peripheral surface, the irregular shape of the mold is transferred to an ionizable radiation φ-cured resin, and the ionizable radiation is used to illuminate the ionizable radiation. a cured resin layer and a laminate of the transparent resin film while contacting the ion-radiation-curable resin layer with a surface of the mold in the form of the roll, and then removing the cured layer of the ion-radiation-curable resin from the mold And the transparent resin film ~. Thereby, the irregular shape of the mold is transferred to the ionizable radiation-curable resin cured layer carried on the transparent resin film. The ionizing radiation can be a UV ray or an electron beam. From the standpoint of ease of handling and safety, it is preferred to use the UV rays. As the light source for the UV rays, a high-pressure mercury lamp, a metal halide lamp, or the like is preferably used -38-200804919 (34). When irradiating through a transparent resin film containing a UV absorber, it is particularly preferable to use a metal halide lamp including a large amount of visible light components. Further, "V-light bulb" and "D-light bulb" (two registered trademarks) (available from Fusion UV Systems JAPAN Co., Ltd.) are preferably used. The ionizing radiation intensity sufficiently cures the UV curable resin to a degree such that the cured film can be removed from the mold. In order to improve the surface hardness, the cured layer of the ion-curable resin and the laminated plate of the transparent resin layer may be further irradiated from the side of the ion-radiation-curable resin layer. According to the above method, an anti-glare layer (anti-glare film) having a haze of 5% or less can be obtained. Turbidity is defined by JIS K 7136 and is expressed by (diffusion transmittance / total light transmittance) X 1 0 0 (%). As described above, the ionizable radiation-curable resin cured by laminating a fine irregular mold having substantially no flat surface thereon and transferring the irregular shape to the transparent resin film or the transparent resin film is used. At the time of the layer, the anti-glare surface of the transparent resin film will have fine irregularities substantially free of the flat # plane. The anti-glare layer 30 formed by the above method is laminated.  The anti-glare-treated surface (anti-glare surface) faces one surface of the above-mentioned linear polarizing film 20, that is, there is no anti-glare surface facing the linear polarizing film 20, and the first retarding plate and/or the first A second retardation plate is laminated on the other surface of the linear polarizing film 20. Thereby, the anti-glare polarizing film laminate 40 shown in FIGS. 2 and 3 is obtained. In order to laminate the above layer or sheet, it is advantageous to use an adhesive having good transparency such as an acrylic adhesive. The present invention will be exemplified by the following examples, which are not intended to limit the scope of the invention in any way. Example 1 (a) Production of a mold A mirror honing surface having an aluminum roller having a diameter of 300 mm (according to JIS A5 05 6).

A metal mold is obtained by plating nickel with an electroless luster having an irregular surface. These plating conditions were adjusted to form a nickel layer having a thickness of 12 μm. After the plating, the thickness of the nickel layer was measured by a β-ray film thickness meter ("Fisher Scope MMS" available from F i scher Instruments Co., Ltd.) and was 12. 3 microns. (b) Production and evaluation of anti-glare film The photocurable resin composition "GRANDIC 806T" (registered trademark, available from Dainippon Ink & Chemicals Co., Ltd.) was dissolved in ethyl acetate to obtain a solution having a concentration of 50%. Next, the photopolymerization initiator "-40-200804919 (36) LUCLLIN®" (available from B AS F Co., Ltd.) in an amount of 5 parts by weight to 100 parts by weight of the curable resin; : 2,4,6-trimethylbenzimidyldiphenylphosphine oxide was added to the solution to obtain a coating composition. This coating composition was coated on a film of triethylenesulfonyl cellulose (TAC) having a thickness of 80 μm so that the thickness of the coating after drying was 5 μm, followed by drying in a desiccator maintained at 60 ° C. 3 minutes. The dried TAC film was pressed and the irregular surface of the metal mold prepared in (a) was tightly contacted with a rubber roller so that the photocurable resin composition layer faced the nickel plating surface of the mold. In this state, light from a high-pressure mercury lamp having a strength of 200 mJ/cm 2 was irradiated from the TAC film side at an intensity of 20 mW/cm 2 by an h-ray conversion ray meter to cure the photocurable resin composition. . Thereafter, the TAC film with the cured resin layer was removed from the mold to obtain a transparent anti-glare film composed of a laminate having an irregular surface-cured resin layer and the TAC film. The turbidity of the anti-glare film was measured using a haze meter "HM-150" (available from Murakami Color Research Laboratory) in accordance with JIS K 7136, and it was 〇·9%. For measurement, the anti-glare film sample was adhered to the glass plate using an optically clear adhesive to prevent the warpage. The transmission sharpness was measured in accordance with JIS Κ 7105 using an image sharpness measuring instrument "ICM-1DP" (available from Suga Test Instruments Co., Ltd.). For measurement, the anti-glare film sample was adhered to the glass plate using an optically clear adhesive to prevent the warpage from being irregular. Next, the sample was irradiated with light from the back side (the surface was in contact with the glass plate), and the transparency of the transparency was measured. The results are as follows: -41 - 200804919 (37) Optical frequency comb with the following width Transmission clarity 0. 125 mm 3 1. 2% 0. 5 mm 2 7. 9% 1. 0 mm 3 2.  r % 2. 0 mm 5 7. 0 % total 14 8. 2% The reflection sharpness was measured using the same image sharpness measuring instrument "ICM-1DP" used for the above transmission resolution measurement. For measurement, the anti-glare film sample was adhered to the glass plate using an optically clear adhesive to prevent the warpage. In order to suppress reflection on the back side of the back side glass, a black acrylic resin sheet having a thickness of 2 mm was adhered to the exposed surface of the glass sheet to which the antiglare film was adhered. In this state, measurement was performed by irradiating light from the sample side of the anti-glare film. The results are as follows: Optical frequency comb with the following widths Reflective resolution 0" 2 5 mm 3. 2% * 0. 5 mm 1. 5% 1. 0 mm 5. 4% 2. 0 mm 14. 8% plus 21. 7% * : The total elimination of the reflection resolution is excluded. Irradiating the irregularity of the anti-glare film with a parallel beam of ammonia-helium laser tilted from the film normal at a direction of 30 degrees and measuring the change in reflectance in a plane including the film normal and the direction of illumination Measure the reflectivity. The reflectance "32 92 03 optical power sensor" and "32 92 optical power meter" (available from Yokogawa Electric Co., Ltd., pp. 42-200804919 (38)) are used to measure the reflectance. As a result, R ( 30) is 0. 374%, R ( 40) is 0. 00064% and R (60 ) /R ( 30 ) is 0. 000 1 0. The surface shape of the anti-glare film was observed using a confocal microscope "ΡΙ^μ2300" (available from Sensofar Co., Ltd.). For observation, the anti-glare film sample was adhered to the glass substrate with an optically clear adhesive and the irregular surface was outward to prevent warpage. The magnification of the objective lens is 50. The data of the obtained φ is processed according to the above deductive method and the average area of the polygon is calculated to be 5 82 square micrometers. From the three-dimensional coordinate information, it was confirmed that the entire surface of the anti-glare film had fine irregularities but no flat portion. The conditions for producing the mold and the optical properties and surface condition of the anti-glare film (the average area of the polygons in terms of polygons) are summarized in Table 1.
