With the use of a photoalignment film, the present invention provides a liquid crystal display device capable of maintaining a favorable voltage holding ratio and reducing or preventing image sticking, stains, and a decrease in contrast ratio for a long time not only in a room-temperature environment but also in a high-temperature environment; and a method for producing such a liquid crystal display device. The liquid crystal display device of the present invention includes paired substrates; a liquid crystal layer disposed between the substrates; a photoalignment film disposed between at least one of the substrates and the liquid crystal layer; and a polymer layer disposed between the photoalignment film and the liquid crystal layer, wherein the polymer layer has a structure derived from a specific epoxy-based monomer and a structure derived from a specific curing agent.
本发明提供了一种液晶显示装置,通过使用光对准膜,不仅能够在室温环境中,而且能够在高温环境中长时间保持良好的电压保持率,减少或防止图像粘连、污点和对比度下降;本发明还提供了生产这种液晶显示装置的方法。本发明的液晶显示装置包括成对的基板;设置在基板之间的液晶层;设置在至少一个基板和液晶层之间的光对位膜;以及设置在光对位膜和液晶层之间的聚合物层,其中聚合物层具有源自特定环氧基单体的结构和源自特定固化剂的结构。
