Patent ID: 8648975

Claim:
A liquid crystal display device in which a pixel formation portion forming one pixel includes a first sub-pixel portion and a second sub-pixel portion, the liquid crystal display device comprising: a plurality of data signal lines; a plurality of first scanning signal lines that are provided to cross the plurality of data signal lines, and are selectively driven; a plurality of the pixel formation portions that are respectively provided to correspond to intersections of the plurality of data signal lines and the plurality of first scanning signal lines, and form a pixel matrix; a plurality of second scanning signal lines that are provided to correspond to the plurality of first scanning signal lines, and are selectively driven; a plurality of potential varying capacitance lines; and a common electrode, wherein the first sub-pixel portion includes a first switching element having a first electrode connected to the first scanning signal line and having a second electrode connected to the data signal line, and being in an on state when the first scanning signal line is selected, and a first pixel electrode connected to a third electrode of the first switching element and laid out such that a capacitance is formed between the first pixel electrode and the common electrode, the second sub-pixel portion includes a second switching element having a first electrode connected to the first scanning signal line and having a second electrode connected to the data signal line, and being in an on state when the first scanning signal line is selected, a second pixel electrode connected to a third electrode of the second switching element and laid out such that a capacitance is formed between the second pixel electrode and the common electrode, a third switching element having a first electrode connected to the second scanning signal line and having a second electrode connected to one of the potential varying capacitance lines, and being in an on state when the second scanning signal line is selected, and a potential varying capacitance electrode connected to a third electrode of the third switching element and laid out such that a capacitance is formed between the potential varying capacitance electrode and the second pixel electrode, and during each frame period, a second scanning signal line corresponding to each row in the pixel matrix is selected after a first scanning signal line corresponding to the each row is selected.
