Abstract:
A liquid crystal display device with multiple pixels includes a first sub-pixel including, a first liquid crystal capacitance between a common electrode and a first pixel electrode, and a first auxiliary capacitance between the first pixel electrode and a first auxiliary capacitance electrode; a second sub-pixel including, a second liquid crystal capacitance between the common electrode and a second pixel electrode, a second auxiliary capacitance between the second pixel electrode and a second auxiliary capacitance electrode, and a step-down capacitance between the second pixel electrode and a step-down capacitance electrode; a first voltage application unit for applying a common first voltage to the common electrode, the first auxiliary capacitance electrode, and the second auxiliary capacitance electrode; and a second voltage application unit for applying a second voltage, which is different from the first voltage, to the step-down capacitance electrode.
