    • The present invention provides a method for producing a complex phase retarder comprising a first phase retarder of at least one resin film, an adhesive layer and a second phase retarder of a coating layer laminated in this order, the method comprising: preparing a phase retarder with an adhesive where an adhesive layer is formed on a surface of a first phase retarder; applying on a transfer base a coating liquid containing an organic modified clay compound of which the chlorine content is no greater than 2,000 ppm and a binder resin in an organic solvent where the moisture ratio measured using a Karl Fischer's moisture meter is 0.15 wt % to 0.35 wt %; forming a second phase retarder by removing the organic solvent and the water from the applied coating liquid; bonding an exposed surface of the above described second phase retarder to the adhesive layer side of the above described phase retarder with an adhesive; peeling the transfer base from the above described second phase retarder; and forming a second adhesive layer on the surface of this second phase retarder from which the transfer base was peeled.

    • The invention provides a coating liquid containing an organic modified clay complex, being able to reduce the haze value when formed into a coating retardation film and to maintain a high contrast ratio of the liquid crystal display device. The coating liquid is formed into a retardation film and composite polarizing plate, and the composite polarizing plate is applied to a liquid crystal device. The invention also provides a coating liquid for coating a retardation film containing an organic modified clay complex and a binder resin in an organic solvent and having a moisture content in the range from 0.15 to 0.35% by weight as measured with a Karl Fischer moisture meter. A retardation film is formed from the coating liquid for coating the retardation film by forming a composition obtained by removing the organic solvent and water from the coating liquid into a film. A composite polarizing plate is prepared by laminating the polarizing plate, adhesive layer and retardation film in this order. A liquid crystal display device is produced by disposing this composite polarizing plate at one surface of a liquid crystal cell, and another retardation film and polarizing plate on the other surface of the liquid crystal cell.
    • 本发明提供了含有有机改性粘土复合物的涂布液,能够在形成涂布延迟膜时降低雾度值,并保持液晶显示装置的高对比度。 将涂布液形成为延迟膜和复合偏光板,将复合偏振片涂布在液晶装置上。 本发明还提供一种用于在有机溶剂中涂覆含有有机改性粘土复合物和粘合剂树脂的相位差膜并用水分含量为0.15至0.35重量%,用Karl Fischer水分计测量的涂布液。 由用于涂布相位差膜的涂布液形成通过将有机溶剂和水从涂布液中除去而得到的组合物形成膜的延迟膜。 通过依次层叠偏光板,粘合剂层和延迟膜来制备复合偏光板。 通过将该复合偏光板设置在液晶单元的一个表面上,在液晶单元的另一个表面上设置另一个延迟膜和偏光板来制造液晶显示装置。
