Zusammenfassung:	To provide an aligned liquid crystal film which has superior heat durability and exhibits less variations in optical properties even when exposed to a high-temperature environment for a prolonged period of time.SOLUTION: An aligned liquid crystal film (100) provided herein comprises a first aligned liquid crystal layer (1) having liquid crystal molecules aligned therein, a resin coating layer (6) abutting a first principal surface of the first aligned liquid crystal layer, and an optical layer (4) bonded to the resin coating layer (6) via an adhesive layer (3). The resin coating layer is a non-curable resin layer. The resin coating layer may have a glass transition temperature of 20°C or higher. The first aligned liquid crystal layer may contain homogeneously aligned liquid crystal molecules.SELECTED DRAWING: Figure 1 【課題】高温環境に長時間暴露された場合でも、光学特性の変化が小さく、加熱耐久性に優れる配向液晶フィルムを提供する。【解決手段】液晶配向フィルム（１００）は、液晶分子が配向した第一配向液晶層（１）、第一配向液晶層の第一主面に接する樹脂コート層（６）、および樹脂コート層（６）上に接着剤層（３）を介して貼り合わせられた光学層（４）を備える。樹脂コート層は、非硬化型樹脂層である。樹脂コート層のガラス転移温度は２０℃以上であってもよい。第一配向液晶層は、液晶分子がホモジニアス配向したものであってもよい。【選択図】図１
