Patent ID: 8922601

Claim:
A liquid crystal display apparatus, comprising: a plurality of pixels, wherein each pixel of the plurality of pixels includes a first sub-pixel and a second sub-pixel, wherein the first sub-pixel and the second sub-pixel of a same pixel receive a same data signal and gate signal, wherein the first sub-pixel and the second sub-pixel include a first pixel electrode and a second pixel electrode, respectively, wherein the first pixel electrode and the second pixel electrode have a first voltage difference at least during a light-emitting period, when a backlight unit emits light, wherein the first sub-pixel includes: a first switching transistor including a gate electrode connected to a gate line, a first electrode connected to a data line, and a first electrode connected to the first pixel electrode; a first storage capacitor connected between the first pixel electrode and a common voltage line that receives an alternating current (AC) common voltage; and a first liquid crystal layer interposed between the first pixel electrode and a common electrode connected to a liquid crystal common voltage line, and wherein the second sub-pixel includes: a second switching transistor including a gate electrode connected to the gate line, a first electrode connected to the data line, and a second electrode connected to the second pixel electrode, the gate electrode of the second switching transistor and the gate electrode of the first switching transistor on opposite sides of the gate line; a second storage capacitor connected between the second pixel electrode and a storage common voltage line that receives a constant storage common voltage; and a second liquid crystal layer interposed between the second pixel electrode and the common electrode, wherein the AC common voltage is less than the constant storage common voltage during a data storage period and is greater than the constant storage common voltage during a light-emitting period.
