To provide a pixel matrix and the like, which are capable of improving the picture quality by suppressing generation of flicker and crosstalk without deteriorating the numerical aperture of the pixels and without increasing the manufacturing cost. A first switch device has transistors connected in series. When selected by a gate line, the transistors are set ON simultaneously to apply a voltage, which is supplied from a data line, to a pixel electrode. A second switch device has a transistor and a control capacitor. When selected by a gate line different from the one mentioned above, the transistor is set ON to supply a prescribed potential to a connection point between the transistors of the first switch, and the prescribed potential is stored at the control capacitor. When not selected by the both gate lines, the potential of the connection point is kept to the potential stored at the control capacitor.
