An object of the present invention is to provide a thin film with excellent adhesion between a support and an intermediate layer, maintaining optical characteristics suitable for optical compensation of a liquid crystal display device in a transverse electric field mode, and a desired tear strength. Providing a retardation film that, when bonded to a polarizing plate, excels in polarizing plate durability in a humid heat environment. A retardation film having a support, an intermediate layer, and a retardation layer in which the alignment state of a liquid crystal material is fixed in this order, wherein the support has an average acyl group substitution degree DS of 2.0 <DS <2. 6 and a specific polycondensation ester or a specific sugar ester, the intermediate layer contains a polyvinyl alcohol resin, or an acrylic resin having a polar group, and the retardation layer has a homeotropic alignment. A retardation film containing a liquid crystal compound having specific optical characteristics. [Selection] Figure 1 |
