An LCD includes an insulating substrate ( 30 ) with gate lines ( 32 ) and data lines ( 31 ) disposed thereon. The gate lines are parallel to each other and extend along a first direction, and the data lines are parallel to each other and extend along a second direction. The data lines cross the gate lines thereby defining a multiplicity of pixel regions ( 3 ). Each of the pixel regions includes a TFT ( 35 ), a pixel electrode ( 33 ) connected to the TFT, a common electrode ( 36 ) connected to a corresponding one of the data lines, and a dielectric layer ( 37 ) disposed between the common and pixel electrodes. The common electrode includes a plurality of protrusions ( 34 ). The protrusions, the dielectric layer, and the pixel electrode cooperatively define a storage capacitor ( 50 ) for holding the pixel region at a set voltage level until the next refresh cycle when the TFT is turned off.
