Patent ID: 8045118

Claim:
A liquid crystal display comprising: an array substrate comprising a pixel electrodes structure and a thin film transistor (TFT) where the TFT is operable to selectively couple a supplied data voltage to electrodes of the pixel electrodes structure; an opposite substrate facing the array substrate; and a liquid crystal material layer interposed between the array substrate and the opposite substrate, wherein: the pixel electrodes structure comprises: a main storage electrode (MSE) receiving a first common voltage whose voltage level can be varied; a main pixel electrode (MPE) overlapped with the main storage electrode and coupled to the TFT so as to receive the data voltage as a main pixel voltage, where the main pixel voltage can thereafter be changed in accordance with the voltage variation of the first common voltage; and a sub pixel electrode (SPE) that is spaced apart from the main storage electrode and is coupled to the TFT so as to receive the data voltage as a sub pixel voltage, where the sub pixel voltage is not changed in accordance with the voltage variation of the first common voltage, and wherein the liquid crystal of the liquid crystal material layer has a dielectric anisotropy (Δ∈) in a range of about −3.8 to about −2.2.
