Thus, the exemplary word "below or beneath" can encompass both the downward and upward directions. The constituent elements can be arranged in a different direction, and the spatially relative words can be interpreted correspondingly according to the direction. An optical film according to an embodiment of the present invention will hereinafter be described with reference to Figs. 1 to 4. 1 to 4 are cross-sectional views illustrating an optical film according to an embodiment of the present invention. In addition to a light diffusing function, and diffractive and condensing to enhance one of the brightness convergence functions, the optical films 100, 110, 120, and 130 according to embodiments of the present invention have a protective function to prevent and close the optical film. Scratches occur between the other members of the sheets 100, 110, 120, and 130. The optical film 100 according to an embodiment of the present invention may include a transparent substrate 10 and at least one 3D pattern layer 20 and 30 respectively disposed on one side 12 and the other side 14 of the transparent substrate 10. As shown in FIG. 1, the first 3D pattern layer 20 can be included on one side 12 of the transparent substrate 10, and the second 3D pattern layer 30 can be included on the other side 14 of the transparent substrate 10. 7 201003222 The transparent substrate ίο is shaped as a plate formed by allowing a light to pass through a colorless transparent synthetic resin. The synthetic resin forming the transparent substrate 10 is not particularly limited, but may include polyethylene terephthalate, polyethylene naphthalate, acrylic resin, polycarbonate, polystyrene, polyolefin, cellulose acetate. (cellous acetate), for gas gathering, for example. Among these materials, polyethylene terephthalate or polycarbonate having an excellent transparency and polyethylene terephthalate having an enhanced warpage property are preferred. The thickness of the transparent substrate 10 is not particularly specified, but may be 0 to 1000 μm, preferably 25 to 600 μm, for example. Within the above thickness range, the transparent substrate 10 exhibits excellent mechanical strength and thermal stability, and has a suitable flexibility, while the loss of transmitted light is small. The first 3D pattern layer 20 is disposed on one side 12 of the transparent substrate 10. The first 3D pattern layer 20 functions to enhance brightness by diffusing or condensing light. The first 3D pattern layer 20 may have a series of meandering patterns along its upper surface.

The first 3D pattern layer 20 may have a relatively high refractive index, such as 1.53 and higher, and preferably 1.54 to 1.60. This higher refractive index increases a convergence capability, which in turn increases brightness. Further, the first 3D pattern layer 20 may have an average thickness of about 10 to 300 μm. It is difficult to achieve a sufficiently large converging effect when the first 3D pattern layer 30 has an average thickness of 10 μm or less, and is easily broken when the average thickness is 300 μm or more. / The second 3D pattern layer 30 is disposed on the other side 14 of the transparent substrate 10 including the first 3D pattern layer 20 on one side 12 thereof. The second 3D pattern layer 30 has a function of diffusing light and can be shaped as a rough embossing. The second 3D pattern layer 30 increases the brightness by diffusing and transmitting the light incident from the light source, and masks a dot pattern printed on a cold cathode fluorescent lamp (CCFL) or a light guide plate functioning as a light source. The plurality of protrusions in an embossed form of the second 3D pattern layer 30 may be shaped into various shapes such as a sphere, a spheroid, a square pyramid, and a fiber, but the invention is not particularly limited to this shape . The second 3D pattern layer 30 may have a relatively low refractive index, such as a refractive index of 1.53 or less, preferably 1.45 to 1.52. The lower refractive index is increased in efficiency such that light incident on the second 3D pattern layer 30 is incident on the first 3D pattern layer 20 through the transparent substrate 10 without being reflected by the first 3D pattern layer 20. Also, the second 3D pattern layer 30 may have an average thickness of about 0.1 to 300 microns. The second 3D pattern layer 30 hardly covers the printed pattern of the 9 201003222, ..., s: 3⁄4 guide plates when the average thickness is 0.1 micron or less, and does not increase the brightness, but the average thickness is lion micron or thicker. It is easy to break. And 'the functional bead 15 as shown in Fig. 2 can be sandwiched between the permeable bottom 10 and the first 3D pattern layer 3G. At this time, although not shown, the functional bead 15 is on the transparent substrate, and the interposition between the 3D pattern layers 3〇 may include two cases, and the functional bead 15 is placed in contact with the transparent substrate 1 and the transparent substrate 10. Separation. The functional bead 15 can be, for example, a light diffusing bead that enhances the second 3D pattern layer such as the light diffusing function. If the functional bead 15 is a light diffusing bead, the light that is emitted from the second smear pattern layer 30 toward the transparent substrate 1b can be uniformly diffused. When the functional bead 15 is a light diffusing bead, the light diffusing bead may be an inorganic filler or an organic filler. The inorganic filler may contain, for example, cerium oxide, aluminum hydroxide, aluminum oxide, zinc oxide, cerium sulfide, and magnesium ruthenate, and thus one or a mixture of at least two of the above inorganic fillers may be used. The organic filler may use a plurality of multi-component base particles formed by covering another monomer after forming the following particles: a bupropion-based particle composed of a homopolymer or a copolymer of the following: : for example, methyl methacrylate, acrylic acid, methacrylic acid, f-based hydroxyethyl acrylate, hydroxypropyl methacrylate, acrylamide, methylol acrylamide, glycidyl methacrylate, acrylic acid B Ester, isobutyl acrylate, n-butyl acrylate, and 2-ethylhyxylacrylate; dilute hydrocarbon-based particles such as polyethylene, polysthylene, and polypropylene; Dilute hydrocarbon based copolymer particles and homopolymer particles. 10 201003222 The above-mentioned inorganic filler or organic filler, referred to as a light diffusing bead, is provided solely for the purpose of release, and can be achieved by those skilled in the art to achieve the primary object of the present invention but not defined as the inorganic filler. The agent or another material of the organic filler is substituted. The functional bead 15 has a particle distribution in which both monodisperse and polydisperse are present. The shape thereof is not particularly limited, and can be shaped into a sphere, a shaft, a needle, a rod, a cube, a plate, and a scale. And the like, one of the spherical bead systems having an excellent light diffusing property is the optimum form. The average diameter of the functional beads 15 may be from 1 to 150 μm, preferably from 1 to 1 μm, for example. If the average diameter of the functional beads 15 is 1 micron or less and ι micron or larger, the diffusion effect is easily insufficient, thereby reducing the mask relative to the light source and the printed pattern of the light guide plate. performance. Also, the content of the functional beads 15 may be about 1 to 80 wt 〇 / 相对 with respect to the total composition of the second 3D pattern layer 30. Although not shown, it is apparent that the above-described functional beads 15 may be added between the transparent substrate 1'' and the -3d pattern layer 20.

For the first 3D pattern layers 20, 40 and 50 and the second 3D pattern layer 30 comprising the ruthenium acrylate, the surface friction coefficient is low due to the sliding property of the ruthenium itself, and provides an excellent processable type, first The surfaces of the 3D pattern layers 20, 40, and 50 and the second 3D pattern layer 30 are not damaged even when a mask is not separately formed thereon. In addition, the first 3D patterns 20, 40, and 50 for masking the germanium-containing acrylate are provided on the first 3D pattern layers 20, 40, and 50, and the first 3D pattern layers 20, 40, and 50 are protected. A protective film of the display panel on the upper surface, one of the nine figures shows that one of the polarizing films of the panel 220 is not damaged. An optical film according to another embodiment of the present invention will now be described with reference to Figs. 5 to 8. 5 to 8 are cross-sectional views showing an optical film according to another embodiment of the present invention. The optical films 140, 150, 160 and 170 according to this embodiment have a predetermined surface roughness on the top surface of the first 3D pattern layers and the optical films 100, 110 of the above-described embodiments of the present invention. 120 and 130 are essentially the same. Thus, the description of the optical film according to this embodiment of the present invention will focus on the difference from the optical film of the above embodiment of the present invention. As shown in FIG. 5, the optical film 140 according to this embodiment of the present invention comprises a transparent substrate 10, one of the first 3D pattern layers 60 on one side 12 thereof and one on the other side 14 thereof. The second 3D pattern layer 30. In addition, as shown in FIG. 6, the functional beads 15 may be disposed between the transparent substrate 10 and the second 3D pattern layer 30. Although not shown, the functional bead 15 may be disposed between the transparent substrate 10 and the first 3D pattern layer 60 12 201003222. The transparent substrate 10, the functional beads 15 and the second 3D pattern layer 30 are substantially identical to those of the optical film 100 of the first embodiment of the above-described embodiment of the present invention. Therefore, it will not be repeated here. The first 3D pattern layer 60 disposed on one side 12 of the transparent substrate 10 for concentrating light to enhance brightness may have various 3D patterns having a predetermined surface roughness on the top surface thereof. As shown in Figs. 5 and 6, the first 3D pattern layer 60 may have a series of ruthenium patterns having a predetermined surface roughness on the top surface thereof. For example, the surface roughness can be provided on the top surface of the first 3D pattern 60 by grinding. The first 3D pattern layer having a meandering pattern having the predetermined surface roughness on its top surface increases the brightness of an image that is monitored by an observer by means of a display device. As shown in Fig. 7, a first 3D pattern layer 70 may be provided with a lenticular pattern or a microlens pattern having a predetermined surface roughness on its top surface. The first 3D pattern layer 70 having a lenticular pattern or a microlens pattern having a predetermined surface roughness on its top surface can diffuse light one-dimensionally perpendicular to the lenticular pattern or the groove of the microlens pattern. As shown in FIG. 8, a first 3D pattern layer 80 may have a Fresnel pattern having a predetermined surface roughness on its top surface, which may have various forms on top of it in addition to the above pattern. The surface has a 3D pattern of predetermined surface roughness. As shown in FIGS. 5 to 8, the surface roughness of the first 3D pattern layers 60, 70, and 80 having various forms of 3D patterns having a predetermined surface roughness on the top surface may be 0.05 to Between 0.5 microns, for example. This is because the peaks of the crucible cannot be covered, and when the surface roughness is 0.05 μm or less, it is liable to be damaged by friction with an adjacent surface, and when it exceeds 0.5 μm, the luminance is liable to be lowered. Further, the ratio of the area of one of the surface roughnesses to the total area of one of the 3D patterns in the first 3D pattern layers 60, 70 and 80 may be, for example, about 10 to 100%. This is because the peaks of the crucible cannot be covered, and when the ratio of the area of the first pattern layers 60, 70, and 80 having the surface roughness is less than 10%, it is easy to be adjacent to Surface friction is damaged. The first 3D pattern layers 60, 70, and 80 having a predetermined surface roughness enhance light diffusion efficiency because light incident through the back surface of one of the transparent substrates 10 is incident on the optical films 140, 150, 160 The outer portions of 170 and 170 are uniformly diffused due to the fine roughness formed in the surface roughness. Additionally, the first 3D pattern layers 60, 70, and 80 may comprise the oxime acrylates similar to those of the optical films of the above-described embodiments of the present invention. The first 3D pattern layers 60, 70 and 80 comprising ruthenium acrylate have excellent processability and have a surface which is not damaged even if a mask is not separately attached. Further, a polarizing film of a display panel is not damaged even when a protective film for the display panel disposed on the upper surface of one of the first 3D pattern layers 60, 70 and 80 is not used alone. The first 3D pattern layers 60, 70 and 80 may have a refractive index higher than a refractive index of the second 3D pattern layer 30, for example at least 1.53 and higher, preferably 1.54 to 1.60. The first 3D pattern layers 60, 70 and 80 may have an average thickness of about 10 to 300 microns. And, although not shown in the figure, if the first 3D pattern layers 70 and 80 each have a surface having a lenticular pattern, a microlens pattern or a Fresnel pattern, the functional beads 15 may be added to the transparent substrate 10 and Between the first 3D pattern layers 70 and 80, or between the transparent substrate 10 and the second 3D pattern layer 30. 14 201003222 The optical film according to another embodiment of the present invention is respectively provided with a 3D pattern layer on one side and the other side of the transparent substrate, and the enamel acrylate is contained in the upper 3D pattern layer, and selectively With functional beads or surface roughness. Thus, the diffusing function, the concentrating function and the protective function can be ensured by the single optical film.
