Patent ID: 8035596

Claim:
A liquid crystal display device comprising a pixel matrix configured with pixels, each having pixel electrode, which are provided near intersection points of a plurality of gate lines and a plurality of data lines, wherein each of the pixels comprises: a first switch device having a plurality of transistors A connected in series, for applying a voltage supplied from one of the plurality of data lines to the pixel electrode when the plurality of transistors A are set ON simultaneously, when selected by a first gate line that is one of the plurality of gate lines; and a second switch device having a transistor B and a capacitor, for supplying a prescribed potential at least to one of connection points between the plurality of transistors A and stores the prescribed potential at the capacitor when the transistor B is set ON, when selected by a second gate line that is one of the plurality of gate lines but different from the first gate line, and keeping at least one of potentials of the connection points at the capacitor between the plurality of transistors A, when not selected by the first gate line and the second gate line.
