The invention provides a liquid crystal display element which has high off-response speed, excellent balance between driving voltage and transmittance, further stability over time and good voltage holding ratio. The liquid crystal display element comprises a liquid crystal layer containing a polymer network (A) and a liquid crystal composition (B) sandwiched between 2 substrates at least one of which has an electrode and at least one of which has transparency, wherein the liquid crystal layer has a loss factor (tan delta) (loss modulus/storage modulus) in the range of 0.1 to 1, the loss factor (tan delta) being calculated from a storage modulus (Pa) and a loss modulus (Pa) measured by a rheometer and measured at a frequency of 1Hz and subjected to sinusoidal oscillation at 25 ℃. |
