Abstract
A liquid crystal display element including a first electrode substrate having a first transparent substrate, a first electrode formed on the first substrate, and a first alignment layer formed on the first substrate. The liquid crystal display element further includes a second electrode substrate having a second transparent substrate, a second electrode formed on the second substrate, and a second alignment layer formed on the second substrate. The liquid crystal display element also has a light modulating layer of a smectic liquid crystal material which is sandwiched between the first and second electrode substrates and which has a thresholdless voltage-transmittance characteristic and a spontaneous polarization of 120 nC/cm or less. Further, the polarity force component of the surface free energy of each of the first and second alignment layers is 13 dyn/cm or less.
