ABSTRACT:
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.
