Patent ID: 8194196

Claim:
A liquid crystal display device, comprising: a first electrode on a substrate to which a first current is fed in a first direction; a second electrode on the substrate and separate from the first electrode to which a second current is fed in a second direction substantially opposite to the first direction; a liquid crystal layer driven with a driving magnetic field induced by the first current and the second current of the first and second electrodes for modulating a light; a polarizer on the substrate; and an alternating current voltage source, wherein polarities of the current of the first and second electrodes are inverted for each frame interval, wherein a first magnetic field generated by the first current and a second magnetic field generated by the second current each have a magnetic field component in the thickness direction of the substrate in the liquid crystal layer having the same direction that in combination form the driving magnetic field such that liquid crystal molecules of the liquid crystal layer are rotated in the thickness direction in a vertical switching mode, wherein at least one of the first and second electrodes is a transparent electrode, wherein the light to the liquid crystal layer via the polarizer and the substrate has a polarized component changed by the liquid crystal molecules having an orientation angle, wherein the liquid crystal molecules are rotated in a direction of an induced magnetic field formed in the thickness direction of the substrate similar to an electric field system, and wherein the first electrode and the second electrode are disposed in a transmittance region of the substrate.
