[0160]1-1. Retardation Film 1
[0161]Polymerization was performed using a batch polymerization apparatus formed of two vertical reactors each including a stirring blade and a reflux condenser controlled to 100° C. 9,9-[4-(2-Hydroxyethoxy)phenyl]fluorene (BHEPF), isosorbide (ISB), diethylene glycol (DEG), diphenyl carbonate (DPC), and magnesium acetate tetrahydrate were loaded at a molar ratio of BHEPF / ISB / DEG / DPC / magnesium acetate=0.438 / 0.537 / 0.025 / 1.005 / 1.00×10−5. The inside of a first reactor was sufficiently purged with nitrogen (oxygen concentration: 0.0005 vol % to 0.001 vol %), and then heated with a heating medium. When the internal temperature reached 100° C., stirring was started. The internal temperature was caused to reach 220° C. after 40 minutes from the start of the temperature increase. While the temperature was controlled to be kept at this temperature, pressure reduction was simultaneously started, and the pressure was caused to reach 13.3 kPa in 90 minutes after the ...

[0193]2-1. Transparent Conductive Film 1
[0194](Formation of Cured Resin Layer)
[0195]A spherical particle-containing curable resin composition containing 100 parts by weight of a UV-curable resin composition (manufactured by DIC Corporation, product name: “UNIDIC (trademark) RS29-120”) and 0.002 part by weight of acrylic spherical particles having a mode particle diameter of 1.9 μm (manufactured by Soken Chemical & Engineering Co., Ltd., product name: “MX-180TA”) was prepared. The prepared spherical particle-containing curable resin composition was applied onto one surface of an elongate substrate having a thickness of 23 μm and a width of 1,550 mm (polycycloolefin film, manufactured by Zeon Corporation, product name: “ZEONOR (trademark)”) to form an applied layer. Then, the applied layer was irradiated with UV light from the side on which the applied layer had been formed, and thus a second cured resin layer was formed so as to have a thickness of 1.0 μm. A first cured resin layer w...

[0200]3-1. Transparent Conductive Film 2
[0201]A transparent conductive film 2 was produced in the same manner as the transparent conductive film 1 except that the substrate was changed from the polycycloolefin film to a polyethylene terephthalate (PET) film (thickness: 23 μm).
[0202]3-2. Production of Optical Laminate 3
[0203]The protective film B1 (without the hard coat layer) was bonded to one side of the polarizer A1 through the intermediation of the UV-curable adhesive. Then, the transparent conductive film 2 was bonded to the protective film B1 side of the laminate of the polarizer A1 and the protective film B1 through the intermediation of the pressure-sensitive adhesive. Further, the protective film B1 subjected to the hard coat treatment was bonded to the ITO side thereof through the intermediation of the pressure-sensitive adhesive. Further, the retardation film was bonded to the other side of the polarizer A1 through the intermediation of the UV-curable adhesive. In this cas...
