Claim:
1. A liquid crystal display, comprising: a first insulation substrate; a gate line and a data line disposed on the first insulation substrate; a first electrode and a second electrode disposed on the gate line; an insulating layer interposed between overlapping portions of the data line and the gate line; a second insulation substrate facing the first insulation substrate; and a liquid crystal layer disposed between the first insulation substrate and the second insulation substrate, the liquid crystal layer comprising liquid crystal molecules and a chiral dopant, wherein a content of the chiral dopant is about 1% by weight, based on the total weight of the liquid crystal layer, and wherein a rotated direction of a long axis of the liquid crystal molecules depending on a direction of an electric field generated by the first electrode and the second electrode and a twisted direction of the liquid crystal molecules depending on the directivity of the chiral dopant are almost the same, wherein the rotated direction of the long axis of the liquid crystal molecule having positive dielectric anisotropy is parallel to the direction of the electric field and the rotated direction of the long axis of the liquid crystal molecule having negative dielectric anisotropy is perpendicular to the direction of the electric field, and wherein the twisted direction of the liquid crystal molecules is a counterclockwise direction when the chiral dopant has a right-handed rotator and the twisted direction of the liquid crystal molecules is a clockwise direction when the chiral dopant has a left-handed rotator.
