A liquid crystal display element utilizing dynamic scattering effects uses a liquid crystal material which is a mixture of at least one kind of liquid crystal having a relatively small birefringence and at least one kind of liquid crystal having a relatively great birefringence, and which has a birefringence of 0.14 to 0.21 when measured with light of 589 nm wavelength at 20°C.
