Patent ID: 8368626

Claim:
A liquid crystal display device with multiple pixels provided therein, comprising: multiple pixel electrodes arranged in a horizontal direction and a vertical direction, said pixel electrode including a first sub-pixel electrode and a second sub-pixel electrode disposed adjacent to said first sub-pixel electrode; a common electrode disposed opposite to said multiple pixel electrodes; plural scanning signal lines extending in the horizontal direction; a first liquid crystal capacitance formed with a liquid crystal sandwiched between said common electrode and said first sub-pixel electrode; a first auxiliary capacitance formed with a solid dielectric material sandwiched between said first sub-pixel electrode and a first auxiliary capacitance line extending in the horizontal direction; a second liquid crystal capacitance formed with said liquid crystal sandwiched between said common electrode and said second sub-pixel electrode; a second auxiliary capacitance formed with a solid dielectric material sandwiched between said second sub-pixel electrode and a second auxiliary capacitance line extending in the horizontal direction; a step-down capacitance formed with a solid dielectric material sandwiched between said second sub-pixel electrode and a step-down capacitance line, said step-down capacitance line being different from any one of said plural scanning signal lines and from said second auxiliary capacitance line, and extending in the horizontal direction; a first voltage application means for applying a common first voltage to said common electrode, said first auxiliary capacitance line, and to said second auxiliary capacitance line; and a second voltage application means for applying a second voltage, which is different from a voltage applied to said scanning signal line and from said first voltage, to said step-down capacitance line, wherein said first voltage is a rectangular AC voltage that oscillates at a specified amplitude, and said second voltage is a rectangular AC voltage whose amplitude is smaller than said specified amplitude of said first voltage.
