The present invention provides a liquid crystal display device with a high degree of freedom in molecular structure design of an alignment film and with reduced image sticking. The liquid crystal display device includes a pair of substrates; a liquid crystal layer held between the substrates; an alignment film disposed on a liquid crystal layer side surface of at least one of the substrates; and a polymer layer disposed between the liquid crystal layer and the alignment film, the alignment film containing a first polymer containing at least one structure represented by the following formula (1) in a side chain,
wherein R1 represents a C3-C6 branched or cyclic alkylene group, and a hydrogen atom at a para position to a carbonyl group in the phenyl group is optionally replaced.
本发明提供了一种液晶显示装置,其对准膜的分子结构设计自由度很高,并能减少图像粘连。该液晶显示装置包括一对基板;夹持在基板之间的液晶层;设置在至少其中一个基板的液晶层侧表面上的对准膜;以及设置在液晶层和对准膜之间的聚合物层,对准膜含有第一种聚合物,其侧链中至少含有一种由下式(1)表示的结构、
其中 R1 代表 C3-C6 支链或环状亚烷基,苯基中对位至羰基的氢原子可选择被取代。
