A retardation film refers to a film in which the refractive index of light differs between when polarized light is incident so as to vibrate parallel to the molecular chain of a polymer and when it is incident at right angles.
This film prevents light from appearing colored in a white liquid crystal display and makes the liquid crystal display black and white. When the retardation film is manufactured from a polysulfone-based polymer film or the like, the film is poor in slipperiness, so that the film is apt to be wrinkled when wound on a core and easily scratched on the surface. There was a problem.

[0003] Therefore, when winding or storing or transporting the phase difference film around a core, the process is performed in the state of a phase difference film bonded body in which a protective film is bonded to the phase difference film via a predetermined adhesive.

At the time of winding the retardation film adhered body, one end of the retardation film adhered body 10 is fitted to the step 36 of the core 18 and the core 18 is rotated, so that the retardation film adhered body 10 is wound. Will be taken.

Here, since the height of the step 36 is the same as the thickness of the retardation film bonded body 10, the surface near the end 40 of the outer periphery of the phase difference film bonded body 10 and the step forming member 38 are continuous. Is formed. Since the vicinity of the end portion 40 of the phase difference film stuck body 10 and the step forming member 38 form a continuous surface, the end portion 40 of the phase difference film stuck body 10 is formed.
Does not cut into the back of the second volume.

According to such a winding method of the retardation film bonded body, one end of the retardation film bonded body 10 is aligned with the step 36 of the core 18 so that the phase difference film bonded body 10
To prevent the end portion 40 of the phase difference film stuck body 10 from biting into the back surface of the second winding, and the contact surface of the back surface of the phase difference film stuck body 10 with the end portion 40 has a scratch. Can be prevented. For this reason, color unevenness does not occur on the contact surface of the back surface of the retardation film bonded body 10 with the end portion 40, and it is possible to prevent the quality of the retardation film 12 from being impaired.

Further, the winding method of the retardation film bonded body according to the present invention may be a method as shown in FIG. The winding method of this retardation film-adhered body is the same as that of the core 4
This is a method in which a step 44 is provided on 2 itself, and one end of the retardation film bonded body 10 is aligned with the step 44, and the phase difference film bonded body 10 is wound.

Even by such a winding method of the retardation film bonded body, the end 4 on the back surface of the retardation film bonded body 10 can be formed.
No color unevenness occurs on the contact surface with 0, and it is possible to prevent the quality of the retardation film 12 from being impaired.

Next, the winding method of the retardation film bonded body according to the present invention may be a method as shown in FIG. This winding method of the phase difference film bonded body is a method of winding the phase difference film bonded body 10 in which the protective film 16 is bonded to the phase difference film 12 via the adhesive 14 onto a cylindrical core 18. A tape (strip-like member) 48 extending in the circumferential direction is fixed to the outer periphery near both ends in the longitudinal direction of the core 18, and the retardation film-adhered body 10 is brought into contact with the outer peripheral surface of the tape 48, while floating from the core 18. , And is wound around the core 18.

A method of winding the phase difference film-adhered body will be described in detail. A tape 48 coated with an adhesive on the back surface is wound around the core 18 in the vicinity of both ends in the longitudinal direction in advance and fixed. Is formed. Here, tape 4
8 may be wound around the center of the core 18 in the longitudinal direction.

When the phase difference film stuck body 10 is wound while being brought into contact with the outer peripheral surface of the tape 48, the tape 48 in the phase difference film stuck body 10
The portion that does not contact the outer peripheral surface of the core 18 is floated from the core 18. That is, a gap 50 is generated between the phase difference film stuck body 10 and the core 18. In addition,
In FIG. 5, the thicknesses of the tape 48 and the gap 50 are exaggerated. The retardation film-attached body 10 is lifted from the core 18 so that the retardation film-attached body 10
Is wound around the core 18 with a certain degree of elasticity.

According to such a method for winding a retardation film-adhered body, the retardation film-adhered body 10 can be wound while being lifted from the core 18. For this reason, there is no contact with the core 18 during storage or transportation of the retardation film bonded body 10, and the retardation film 12 is not damaged. Further, since the phase difference film stuck body 10 is wound around the core 18 in a state having a certain degree of elasticity, the phase difference film stuck bodies 10 wound many times do not come into firm contact with each other. For this reason, it is possible to prevent the quality of the retardation film 12 from being impaired by the pressure due to the contact between the retardation film bonded bodies 10.

According to such a winding method of the phase difference film-adhered body, the protective film 16 side is wound outside with the protective film 16 side disposed outside. In addition, the side of the retardation film 12 facing inward does not contact the inner wall of the packaging box 20. Therefore, the retardation film 12 is not damaged by the inner wall of the packing box 20. Since the retardation film 12 is directed inward, the core 18 may be damaged. However, the area of the contact surface between the retardation film-attached body 10 and the core 18 is determined by the contact area of the packing box 20. Since it is much smaller than the area of the surface, the damage is less than when the retardation film 12 is wound outward.

Next, the method for winding the retardation film-adhered body according to the present invention may be a method as shown in FIG. As shown in FIG. 3, this winding method of the retardation film stuck body adjusts one end of the phase difference film stuck body 10 to the step 36 and, as shown in FIG. It is a method of arranging it outside and winding it up. According to such a winding method of the retardation film bonded body,
The end portion 40 of the retardation film bonded body 10 can be prevented from biting into the back surface of the second winding, and the retardation film 1
2 can be prevented from being damaged by the inner wall of the packing box 20.

Although not shown, it is preferable that the protective film 16 adhered to at least one side of the retardation film 12 be made of a material whose hardness is lower than the hardness of the retardation film 12. Phase difference film stuck body 1
0 is wound around the core 18 so that the retardation film 1
2 and the protective film 16 come into contact with each other and rub against each other, so that even if a frictional force or the like is generated on the contact surface and the surface of the protective film 16 is scratched, the surface of the phase difference film 12 is scratched. Never.
