Description of the Invention (1) Technical Field to which the Invention belongs The present invention relates to a method for manufacturing a three-layer optical film laminate. BACKGROUND OF THE INVENTION Optical films, such as linear polarizing films and phase-difference films, are important for use as optical components constituting liquid crystal display devices. The related optical films are three types of optical films, that is, the first optical film (10), the second optical film (20), and the third optical film (30) are three layers of pre-laminated squares. The optical film laminate wafer (5 1) is often combined into a liquid crystal display device and used. The direction of the optical axis of the liquid crystal display device of the relevant optical film, that is, the display performance of the liquid crystal display device for the purpose of the direction of the absorption axis of the linearly polarizing film, the direction of the retardation axis of the phase difference film, etc. The important elements of this are that even if they are a little different in terms of design, the resulting liquid crystal display device fails to exhibit the intended performance. Therefore, the reference angle (60) of the three-layer optical film laminate wafer combined with the liquid crystal display device, the relative angle of the optical axis (1 1) of the first optical film (2, the optical axis of the second optical film (2 1) The relative angle (02) of the third optical film and the relative angle (θ3) of the optical axis (31) of the third optical film must be strictly managed in a wafer with three optical film laminates (5 1). Therefore, the relative angle (Θ :) of the optical axis of the first optical film is viewed from the side of the first optical film, and the angle of the optical axis (11) of the first optical film to the reference line of the wafer with three optical film laminates (6 0) The angle expressed by the counterclockwise rotation direction as the positive direction, the optical of the second optical film ----- ten-LI I ---------- order ---------线 * _ (Please read the precautions on the back before filling this page) This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) -4- 550420 Printed clothing for employees of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V.

Such a square-shaped three-layer optical film laminate wafer (5 1), for example, shown in Figure 10, is a strip-shaped first optical film (1 2), a strip-shaped The second optical film (2 2) and the strip-shaped third optical film (3 2) are used as raw materials, and thus a square first optical film wafer (1 3) and a square second optical film wafer ( 2 3) and the third third optical film wafer (3 3), which is transparent through The pressure-sensitive adhesive layer can be manufactured by laminating these manufacturing methods. Here, the belt-shaped first optical film (12), the belt-shaped second optical film (22), and the belt-shaped material can be used as raw materials. The third optical film (3 2) is generally used as the raw material of the optical film wafer (1 3, 2 3, 3 3) regardless of which is the linearly polarized film wafer or the phase difference film wafer. The pressure-sensitive adhesive layer is previously provided on one side of, for example, a belt-shaped first optical film, a belt-shaped second optical film, or a belt-shaped third optical film, and these optical film wafers are cut out (1 3, 2 3, 3 3), and when superimposed, the paper size can apply the Chinese National Standard (CNS) A4 (210 X 297 mm) -5---- ten --L ---- Packing -------- Order --------- line (please read the precautions on the back before filling this page) 550420 Printed by A7 B7____ of the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs (3) The objective square three-layer optical film laminate wafer (5 1) is obtained. The related optical film laminate wafer with three layers (5 1), even when combined with different types of liquid crystal display devices and given to the user, the optical axis (2 1) of the second optical film is opposite to the optical axis (1 of the first optical film) 1) The relative angle (and the relative angle (031) of the optical axis (3 1) of the third optical film to the optical axis (11) of the first optical film (031) (Figure 9) is also the same in most cases.
