摘要： A retardation film insusceptible to color dropout or color shift even under environment of severe temperature or humidity conditions and capable of being produced by a melt film-forming method. The retardation film is obtained by molding at least one polymer selected from polycarbonate and polyester carbonate each having a glass transition temperature of 110 to 180° C. and satisfies the relationships of the following formulae (A) and (B): 0.7

摘要： As a result of a reduction in thickness of an IPS liquid crystal display panel, curl has started to occur in a structure where an optical film such as a polarizer or a retardation film is laminated to the IPS liquid crystal display panel. The present invention is directed to thinning a polarizer which is easily expandable and contractable, and thinning a retardation film located between the polarizer and an IPS liquid crystal display panel to enable the polarizer to come closer to the IPS liquid crystal display panel than ever before to thereby prevent curl of the IPS liquid crystal display panel.
