To provide a liquid crystal display device that has a high off-response speed and a good balance between drive voltage and transmittance, is stable over time, and also has a high voltage holding ratio. A liquid crystal display device in which a liquid crystal layer containing a polymer network (A) and a liquid crystal composition (B) is disposed between two substrates having an electrode on at least one side thereof and having transparent properties on at least one side thereof, and the loss factor (tan δ) (loss modulus/storage modulus) of the liquid crystal layer calculated from the storage modulus (Pa) and the loss modulus (Pa) in a sinusoidal vibration measured with a rheometer at 25° C. and at a measurement frequency of 1 Hz ranges from 0.1 to 1.
提供一种液晶显示装置,该装置具有较高的非响应速度,在驱动电压和透射率之间具有良好的平衡,长期稳定,并且具有较高的电压保持率。一种液晶显示装置,其中包含聚合物网络(A)和液晶成分(B)的液晶层被放置在两块基板之间,这两块基板至少有一面具有电极,并且至少有一面具有透明特性,液晶层的损耗因子(tan δ)(损耗模量/存储模量)由存储模量(Pa)和损耗模量(Pa)在正弦振动中计算得出,该振动是在 25 摄氏度和 1 赫兹的测量频率下用流变仪测量的,损耗因子(tan δ)的范围为 0.1 至 1。
