Description of the invention (1) (Technical field to which the invention belongs) The present invention relates to a method for manufacturing an optical film laminated wafer. (Background of the Invention) Optical films represented by polarizing films, retardation films, and the like are extremely important as one of the optical components constituting liquid crystal display devices. For example, in a STN (Super Twisted Nematic) type liquid crystal display device, a square optical film laminated wafer 9 laminated with a first optical film (such as a polarizing film) 19 and a second optical film (such as a retardation film) 2 9 is used. In the optical film laminated wafer, the angle formed by the optical axis (absorptive axis in the polarizing film and late phase in the retardation film) of each optical film is based on the display performance of the obtained liquid crystal display device. It is extremely important that if the design angle is slightly different, the obtained liquid crystal display device cannot perform its intended performance. In this way, in the optical film laminated wafer, the angle θ of the absorption axis 10 of the polarizing film of the reference line or the angle θ 2 of the retardation film 20 of the retardation film must be strictly managed. Normally, the reference line is based on the long or short side of the optical film laminated wafer 9 as the reference side 91, and is set parallel to the reference side = as shown in Fig. 12, in the square optical film laminated wafer 9, The angle 0 1 of the absorption axis 10 of the polarizing film of the reference line and the angle θ 2 of the retardation axis 20 of the retardation are the angles that are viewed from the side of the polarizing film with the counterclockwise rotation direction being positive. The angles θ 1 and 0 2 are used in the second light ^ paper method of the optical film laminated wafer 9.

Description of the invention (2) The optical axis of the film 2 0 The optical axis of the first optical film The relative angle 6 1 of 0 has the relationship represented by the formula (I) {Please read the note on the back before filling the page) θ = Θ 2-θ 1 (I). Here, the relative angle Θ is viewed from the side of the first optical film (such as a polarizing film) of the optical film laminated wafer, and is displayed in a counterclockwise direction as a positive angle. Such an optical film laminated wafer 9 is usually manufactured from a polarizing film ribbon 11 and a retardation film ribbon 21, but usually such ribbons 11, 2 1 are the optical axis (absorption axis, late Phase axis) 10 and 20 are parallel or perpendicular to the longitudinal direction. Therefore, when the absolute angle of the angle Θ1 is not 0 ° or 90 °. In order to manufacture the polarizing film 19 of the square optical film laminated wafer 9, it is a polarizing film. The strip-shaped body 11 is cut out obliquely; and when the absolute angle θ 2 is not 0 ° or 9′0 °, the retardation film is manufactured from a retardation film in order to manufacture a square retardation film of a square optical film laminated wafer 9. The band-like body 21 is cut out obliquely. The manufacturing method of these optical film laminated wafers 9 is printed by the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and a method of cutting a parallelogram optical film laminated body 5 laminated with a polarizing film and a retardation film is known (Japan) (Japanese Unexamined Patent Publication No. 1 1 2 3 1 1 2 9). In this manufacturing method, the optical film laminate 5 is manufactured from a polarizing film ribbon 11 and a retardation film ribbon 21. Specifically, for example, as shown in FIG. 13, the two opposite sides AB and DC of the optical film multilayer body 5 manufactured are parallel to the absorption axis 10 of the polarizing film, while the other two sides BC and AD are slower to the retardation film. The phase axis 20 is parallel. The standard of this paper is applicable. National National Standards (CNS} A4 specifications < 210X297 mm) ~ '-5- 4 63 Ο 6 〇Α7 _____ Β7_ 5. Description of the invention (3) According to the manufacturing method, the dimensions, sizes, The angle θ 1 of the absorption axis of the reference side or the angle β 2 of the late phase axis are different, but they can be cut out from a type of optical film laminate 5 and manufactured to make the relative angle Θ of the slow phase axis to the absorption axis common. A plurality of types of optical film laminated wafers 9 0 However, in this manufacturing method, as shown in FIG. 13, a polarizing film ribbon is used whose absorption axis is parallel to the longitudinal direction, and a retardation film ribbon is used. The retardation axis is parallel to the longitudinal direction, but when the relative angle Θ of the retardation axis to the absorption axis is 40 ° or less or 140 ° or more, the shape of the optical film laminate 5 tends to be slender, so it is not easy to handle. Problem. As a method for solving this problem, as shown in FIG. 14, a method of using a retardation film band body whose vertical phase axis is perpendicular to the longitudinal direction is also described in the publication. According to this manufacturing method, even when the relative angle 0 is 40 ° or less or 140 ° or more, the shape of the optical film laminate 5 does not become slender, and it is easy to handle. However, since the relative angle 0 of the target optical film laminated wafer 9 is various, in this method, whenever the relative angle 0 of the target optical film laminated wafer is replaced, the phase difference film must be tape-shaped. The body 21 has a late phase axis that is parallel to the longitudinal direction and is replaced by a vertical one, and becomes troublesome (FIGS. 13 and 14). (Purpose and Summary of the Invention) The inventor focused on reviewing the paper size of the paper to be developed to replace the optical film laminated wafer. The Chinese national standard (CNS) A4 specification (210X297 mm) is applicable, _. ^-(Please read the back first Please pay attention to this page, please fill in this page) Order printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives-6-463060 at B7 V. Description of the invention (4) The relative angle β is below 40 ° or above 140 °, and it is not necessary to replace The phase difference film ribbon is a method for producing an optical film laminated wafer through an optical film laminated body which is easier to handle.

After the light film sheet was laminated, the phase difference film ribbon was laminated, and along the polarization The optical film laminate obtained by cutting the retardation film ribbon into a thin film sheet is relatively easy to handle even if the relative angle 0 of the intended optical film laminate wafer is 40 ° or less or 14 ° or more. Can be manufactured without changing the phase difference film ribbon. In addition, it was found that by cutting the optical film laminated body 5 obtained by this method, the objective optical film laminated wafer 9 can be efficiently obtained, and the invention was developed.
