To provide a mixed composition for a polymerizable liquid crystal compound that has a low phase transition temperature and is preferably suited for production of a retardation film with excellent optical characteristics.SOLUTION: A mixed composition includes a compound represented by formula (2), and at least one of a compound represented by formula (1) and a compound represented by formula (3). The area percentage value for the compound represented by formula (2), as measured by liquid chromatography, is more than 50% and less than 95% based on the total area value for the compounds represented by formula (1), (2), and (3) within the mixed composition. A-Ar-A (1), A-Ar-B (2) and B-Ar-B (3).SELECTED DRAWING: None 【課題】相転移温度が低く、好ましくは、優れた光学特性を有する位相差フィルムの製造に好適な重合性液晶化合物の混合組成物を提供すること。【解決手段】式（２）で表される化合物と、式（１）で表される化合物および式（３）で表される化合物のうちの少なくとも１つとを含む混合組成物であって、式（２）で表される化合物の液体クロマトグラフィーで測定した面積百分率値が、混合組成物に含まれる式（１）で表される化合物、式（２）で表される化合物および式（３）で表される化合物の面積値の合計に基づいて、５０％を超え９５％未満である、混合組成物。Ａ－Ａｒ－Ａ （１）Ａ－Ａｒ－Ｂ （２）Ｂ－Ａｒ－Ｂ （３）【選択図】なし
