ABSTRACT:
A first common line for supplying a positive phase picture signal and a second common line for supplying a negative phase picture signal are disclosed. A plurality of first switch devices are connected to the first common line. A plurality of second switch devices are connected to the second common line. Each of the first switch devices and each of the second switch devices are paired and connected to one signal line. A first operational amplifier is disclosed between each of the first switch devices and the signal line. The first operational amplifier operates in common with the first switch device group. A second operational amplifier is disclosed between each of the second switch devices and the signal line. The second operational amplifier operates in common with the second switch device group. A common control signal is input from a timing control circuit to the pair of each of the first switch devices and each of the second switch devices. A picture signal is output from the first switch device or the second switch device that is enabled by the first or second operational amplifier.
