Patent ID: 7492426

Claim:
A liquid crystal display comprising: a first insulating substrate; a plurality of first signal lines formed on the first insulating substrate; a plurality of second signal lines formed on the first insulating substrate and insulated from and intersecting the first signal lines; a thin film transistor connected to one of the first signal lines, one of the second signal lines; a pixel electrode coupled to the thin film transistor; a second insulating substrate opposite to the first insulating substrate; a common electrode formed on the second insulating substrate; and a liquid crystal material interposed between the first insulating substrate and the second insulating substrate, wherein liquid crystal molecules contained in the liquid crystal material are aligned substantially perpendicular to the first and the second substrates in absence of electric field between the pixel electrode and the common electrode, and dielectric anisotropy of the liquid crystal material is in a range of less than −4.6 to −5.5, wherein a voltage difference of about 2.2V applied between the pixel electrode and the common electrode makes a transmission of the liquid crystal display equal to or greater than about 10% of a transmittance obtained by applying a voltage difference of about 4.5V between the pixel electrode and the common electrode.
