Patent ID: 7573453

Claim:
A liquid crystal display comprising: a first insulating substrate; a second insulating substrate opposed to and spaced from the first insulating substrate; a plurality of pixel electrodes formed on the first substrate; a common electrode formed on at least one of the first substrate and the second substrate; and a liquid crystal layer interposed between the first substrate and the second substrate, wherein each of the pixel electrodes is divided into a main-pixel electrode and a sub-pixel electrode to form a plurality of main-pixel electrodes and sub-pixel electrodes, to which different signal voltages are individually applied at a same gray scale, and wherein one of the signal voltages to be applied to the sub-pixel electrodes is determined by a gamma value satisfying the following equation Gamma K =(current gray scale/maximum gray scale) f where f (Gray Scale) =α×(maximum gray scale/current gray scale), and α is a constant.
