Liquid crystal display panel, liquid crystal display, and electronic unit |
摘要 |
A liquid crystal display panel includes: a liquid crystal layer including a liquid crystal material with positive dielectric constant anisotropy; a vertical alignment film being in contact with the liquid crystal layer; a first substrate and a second substrate disposed to face each other with the liquid crystal layer in between; and an electrode disposed on a surface of one or both of the first substrate and the second substrate and generating, in the liquid crystal layer, an electric field in a direction orthogonal to or intersecting with a normal to the first substrate. |

1. A liquid crystal display including a liquid crystal display panel, and a drive circuit driving the liquid crystal display panel, the liquid crystal display panel comprising:
a liquid crystal layer including a liquid crystal material with positive dielectric constant anisotropy; a vertical alignment film being in contact with the liquid crystal layer; a first substrate and a second substrate disposed to face each other with the liquid crystal layer in between; and an electrode disposed on a surface of one or both of the first substrate and the second substrate and generating, in the liquid crystal layer, an electric field in a direction orthogonal to or intersecting with a normal to the first substrate, wherein the drive circuit is configured to apply a first voltage to the electrode in a nematic phase temperature range and in an isotropic phase temperature range of the liquid crystal layer, the first voltage being predetermined as a voltage that allows birefringence produced in an isotropic phase to be substantially equal to birefringence produced in a nematic phase, wherein the nematic phase birefringence is a phase birefringence in the nematic phase temperature range in which a direction of a director of the liquid crystal layer is changed by applying the electric field generated by the electrode, and wherein the isotropic phase birefringence is a phase birefringence in the isotropic phase temperature range in which a direction of a director of the liquid crystal layer is dissipated or induced by applying the electric field generated by the electrode. |
