A liquid crystal display device having high transmittance and excellent high-speed response by suppressing rise in driving voltage, suppressing reduction in birefringence and improving transmittance, and improving liquid crystal fall time To provide. A polymer or copolymer is contained in a liquid crystal composition sandwiched between two transparent substrates each having an electrode on at least one, and the content of the polymer or copolymer is the liquid crystal composition and the polymer. Or 1% by mass or more and less than 40% by mass of the total mass of the copolymer, and the polymer network or polymer binder in the liquid crystal composition has an easy alignment axis or refractive index anisotropy, A liquid crystal display element, wherein the liquid crystal compound is aligned parallel to the alignment direction of the alignment film on the liquid crystal cell substrate, and the liquid crystal compound has negative dielectric illegality.
