Abstract
An object of the present invention is to provide a polymer compound in which, by blending with a liquid crystal composition containing a liquid crystalline compound, alignment of the liquid crystalline compound in a phase difference layer to be obtained increases; and a liquid crystal composition, a phase difference layer, an optical film, a polarizing plate, and an image display device using the same. The polymer compound of the present invention is a polymer compound including a repeating unit represented by Formula (I), a repeating unit represented by Formula (II), a repeating unit represented by Formula (III), and a repeating unit represented by Formula (IV).
