In Fig. 3 A and the illustrated such structure of Fig. 3 B, the width that is layered in the 2nd film 32 on the 1st film 31 and the 3rd film 33 is all less than the width of the 1st film 31, the 2nd film 32 and the 3rd film 33 are all to stack gradually on the 1st film 31 in the mode that does not exceed the 1st film 31 on the Width, therefore, bonding coat 32A, the 33A of optical film laminate 30 can not expose to the outside.Thereby, even form optical film laminate 30, this optical film laminate 30 be pasted under the such situation of liquid crystal panel with the width corresponding with the width of the liquid crystal panel of rectangular shape, bonding coat 32A, 33A can not expose to the outside yet, can prevent that the liquid crystal display cells of manufacturing from producing defective.
In addition, as present embodiment, optical film laminate 30 by the coiling manufacturing forms under the situation of continuous material volume R4, can provide bonding coat 32A, 33A can not expose the continuous material volume R4 that reels and form to the optical film laminate 30 of outside.Continuous material volume R4 if so, just can prevent when carrying that dust etc. is attached to bonding coat 32A, 33A or when carrying bonding coat 32A, 33A rub and become the viscosity sphere with outside, therefore, can prevent from effectively producing defective at the liquid crystal display cells that make the conveying destination of continuous material volume R4.
Particularly in the example of Fig. 3 A, the 2nd film 32 and the 3rd film 33 all stack gradually on the 1st film 31 in the mode at the film that does not exceed close the 1st film 31 sides on the Width, therefore, can prevent from exceeding the situation that bonding coat 33A that the 2nd film 32 makes the 3rd film 33 exposes because of the 3rd film 33 as Fig. 3 B along Width.
The width of the 2nd film 32 and the 3rd film 33 also can be identical.The number that is layered in the film on the 1st film 31 also can be for more than 3, and in this case, the width that is layered in all films on the 1st film 31 gets final product less than the width of the 1st film 31.
The width of preferred the 1st film 31 is below the width of the liquid crystal panel that the 1st film 31 will be pasted.For example, liquid crystal panel is under the OBL situation, and the width of the 1st film 31 that the long limit of preferred length direction and liquid crystal panel or minor face are parallel is with the corresponding width of this length limit or minor face or less than the width of this length limit or minor face.On the other hand, preferably be pasted on the width of the film (being the 2nd film 32 and the 3rd film 33 in this example) on the 1st film 31 more than the width of the pixel region of liquid crystal panel.
Fig. 4 represents the cut-open view of Width of the not preferred example of optical film laminate 30.In this Fig. 4, similarly be pasted with film carrier 31B by bonding coat 31A at the 1st film 31 with the example of Fig. 3 A and Fig. 3 B, bonding coat 32A by a side surface that is formed at the 2nd film 32 is pasted on the 1st film 31 with the 2nd film 32, and, bonding coat 33A by a side surface that is formed on the 3rd film 33 is pasted on the 2nd film 32 with the 3rd film 33, thereby has formed optical film laminate 30.
In Fig. 4, at least one in the 2nd film 32 and the 3rd film 33 exceeds near this point of the 1st film 31 different with the example of Fig. 3 A and Fig. 3 B along Width.Therefore, in the such structure of Fig. 4, in bonding coat 32A and bonding coat 33A at least one exposes from the Width both ends of optical film laminate 30, this optical film laminate 30 is pasted under the situation of liquid crystal panel, and the liquid crystal display cells of manufacturing might produce defective because of the dust that is attached to bonding coat 32A, 33A, viscosity sphere etc.
In the example of Fig. 4, all the width with the 1st film 31 is identical for the width of the 2nd film 32 and the 3rd film 33, and each film 31～33 is stacked with the state that staggers mutually along Width.Therefore, the 2nd film 32 and the 3rd film 33 all exceed the 1st film 31 along Width, and the bonding coat 32A, the 33A that are respectively formed at a side surface of the 2nd film 32 and the 3rd film 33 become the state that exposes.
In the explanation of above-mentioned embodiment, there is the situation that optical film laminate is pasted on the example of liquid crystal panel that records, but optical film laminate of the present invention is not limited to the form that is pasted on liquid crystal panel, also can be pasted on other panels, substrate etc.

(embodiment 2)
In embodiment 2, with the pattern of Fig. 3 B stacked the 2nd film 32 and the 3rd film 33 and formed optical film laminate 30 on the 1st film 31.The width of the 2nd film 32 is littler than the width of the 1st film 31, is 397.3mm.The width of the 3rd film 33 is bigger and littler than the width of the 1st film 31 than the width of the 2nd film 32, is 398.6mm.In this case, the bonding coat 32A of the 2nd film 32 does not exceed the 1st film 31, but the bonding coat 33A of the 3rd film 33 is 1mm with respect to the plussage of the 2nd film 32, and the defective generation rate is 1%.
(comparative example 1)
In comparative example 1, with the pattern of Fig. 4 stacked the 2nd film 32 and the 3rd film 33 and formed optical film laminate 30 on the 1st film 31.The width of the 2nd film 32 and the 3rd film 33 all width with the 1st film 31 is identical, is 400.1mm.In this example, the bonding coat 32A of the 2nd film 32 is 0.7mm with respect to the bonding coat 33A of the plussage of the 1st film 31 and the 3rd film 33 with respect to the plussage of the 2nd film 32, and the defective generation rate is 10%.
Above experimental result is illustrated in the following table 1.
＜table 1 〉
The 1st film 31, the 2nd film 32 and the 3rd film 33 preferably comprise double-colored polarization film and polarization by reflection film.In this case, can make and comprise double-colored polarization film and polarization by reflection film and bonding coat 32A, 33A can not expose the optical film laminate 30 to the outside.As long as use such optical film laminate 30, suitably manufacturing defect liquid crystal display cells still less.
Double-colored polarization film is to make and implemented dyeing, crosslinked and extend the dry operation that obtains polarizing coating of the polyvinyl alcohol film of handling, (B) and paste the manufacture method of carrying out the operation of heat treated after the operation, (C) stickup of protective seam in the one-sided or both sides of this polarizing coating and make by for example comprising (A).
The dyeing of polyvinyl alcohol film, each processing crosslinked, that extend do not need to carry out respectively, can carry out simultaneously yet, and in addition, each order of handling also is arbitrarily.In addition, as polyvinyl alcohol film, also can use and implement the polyvinyl alcohol film that swelling is handled.Usually, polyvinyl alcohol film be impregnated in the solution that comprises iodine, bitintability pigment, make iodine, bitintability pigment adsorb and after dyeing, clean, after in the solution that comprises boric acid, borax etc., carrying out uniaxial extension with 3 times～7 times of extension ratios, carry out drying.After in the solution that comprises iodine, bitintability pigment, extending, in the solution that comprises boric acid, borax etc., further extend (two-stage extension) after, carry out drying, thereby the orientation of iodine uprised, the degree of polarization characteristic improves, and therefore, is particularly preferred.
The polarization by reflection film be can by will be for example two kinds of different thin polymer films stacked and extend to make along Width.When extending, the Width both ends of the thin polymer film after stacked with the clamping of horizontal expansion device, are extended towards the Width outside.Thus, only make the refractive index of a kind of thin polymer film in two kinds of thin polymer films increase variation along bearing of trend (Width), present birefringence.Thereby it is that axis of reflection, the length direction that does not produce refringence are the such polarization by reflection film of the axis of homology that there is the Width of refringence in the interface that can make two kinds of thin polymer films.
When making optical film laminate 30, preferably the mode that is parallel to each other with the axis of homology of the axis of homology of double-colored polarization film and polarization by reflection film stacks gradually the 2nd film 32 and the 3rd film 33 on the 1st film 31.Thereby, make with pattern as described above under the situation of polarization by reflection film, for double-colored polarization film, also preference makes thin polymer films such as polyvinyl alcohol film extend along Width as utilizing the horizontal expansion device, is that absorption axes, length direction are the so double-colored polarization film of the axis of homology thereby form Width.
In this case, can make the optical film laminate 30 that the axis of homology of the axis of homology of double-colored polarization film and polarization by reflection film all extends along Width.But the axis of homology of the axis of homology of double-colored polarization film and polarization by reflection film also can be for for example all extending such structure along the direction of intersecting with Width as length direction.Like this, the axis of homology of the axis of homology of double-colored polarization film and polarization by reflection film is configured to be parallel to each other, thereby can make the optical film laminate 30 of the optical characteristics with manufacturing of can be used in liquid crystal display cells etc.
It is the double-colored polarization film of absorption axes (MD) that the 1st film adopts length direction, it is the polarization by reflection film of absorption axes (TD) that the 2nd film adopts Width, the 2nd film is being pasted under the situation of the 1st film, be shorter than the 1st thin-film width by the cut-out spacing that makes the 2nd film, can obtain the 2nd film does not exceed the 1st film on Width the optical film laminate that is laminated (with reference to Fig. 2 B).
