DISPLAY ELEMENT AND DISPLAY UNIT

摘要

A display element comprising a material layer provided between a pair of facing substrates to indicate an optical isotropy when no electric field is applied and exhibit an optical anisotropy when an electric field is applied, display being carried out by applying an electric field to between the pair of substrates. The material layer contains a liquid crystal medium showing a nematic liquid crystal phase, and n× e is at least 1.9 when refractive index anisotropy at 550nm in the nematic phase state of the liquid crystal medium is n and the absolute value of permittivity anisotropy at 1kHz is e . The display element and a display unit provided with the display element are quick in response speed, are low in drive voltage, and can be driven over a wide temperature range.
