LAMINATE ROLL, OPTICAL UNIT, ORGANIC EL DISPLAY DEVICE, TRANSPARENT CONDUCTIVE FILM, AND MANUFACTURING METHOD FOR OPTICAL UNIT

摘要

PROBLEM TO BE SOLVED: To minimize variations of a slow axis direction and in-plane retardation of a transparent conductive film.SOLUTION: A laminate roll is an elongate laminate wound into a roll, and the laminate includes a transparent conductive film including a polycycloolefin film and a transparent conductive layer. In an entire area of the elongate laminate other than two end portions, each corresponding to 5% of a total width thereof, a slow axis direction of the polycycloolefin film is within ±2° of a longitudinal direction of the elongate laminate.SELECTED DRAWING: Figure 7
