1. A display element, comprising:

  • a pair of substrates which are opposed to each other; and

    a substance layer sandwiched between the substrates,the display element performing display operation by applying an electric field to between the substrates,the substance layer including a liquid crystalline medium exhibiting a nematic liquid crystal phase, and exhibiting an optical isotropy when no electric field is applied, while exhibiting an optical anisotropy when an electric field is applied,wherein;


    Δ







    |≧

    1.9,where Δ

    n is a refractive index anisotropy at 550 nm in a nematic phase of the liquid crystalline medium exhibiting the nematic liquid crystal phase, and |Δ



    | is an absolute value of a dielectric anisotropy at 1 kHz in the nematic phase of the liquid crystalline medium exhibiting the nematic liquid crystal phase.
