ABSTRACT:
An LCD panel includes a pixel unit having a first and a second pixel electrodes. The method includes: providing a first and a second curing voltages Vcuring1, Vcuring2based on V1=[Cst1/(Cst1+Clc1)]×Vcuring1and V2=[Cst2/(Cst2+Clc2)]×Vcuring2, in which, V1=a voltage of the first pixel electrode and V2=a voltage of the second pixel electrode, Clc1=a first liquid crystal capacitor formed by the first pixel electrode, a liquid crystal layer and a first common electrode, Cst1=a first storage capacitor formed by a first capacitor electrode, a dielectric layer and a second common electrode, Clc2=a second liquid crystal capacitor formed by the second pixel electrode, the liquid crystal layer and the first common electrode, Cst2=a second storage capacitor formed by a second capacitor electrode, the dielectric layer and a third common electrode, and applying the first and the second curing voltages simultaneously onto the second and the third common electrodes of the pixel unit to result in a ratio of the voltage of the first pixel electrode to the voltage of the second pixel electrode ranging from 0.9 to 1.1.
