Abstract:
1. A display device comprising: a pixel portion to which a non-inverted video signal is input in a first period and to which an inverted video signal is input in a second period; and a signal line driver circuit comprising a switch circuit portion for controlling output of the non-inverted video signal and the inverted video signal to the pixel portion, wherein the switch circuit portion comprises first to third transistors, each of the first to third transistors comprising a gate, a first terminal, and a second terminal, wherein the first terminal of the first transistor is electrically connected to the first terminal of the second transistor and the first terminal of the third transistor, wherein the second terminal of the first transistor, the second terminal of the second transistor, and the second terminal of the third transistor are electrically connected to a first signal line, a second signal line, a third signal line, respectively, wherein the gate of the first transistor, the gate of the second transistor, and the gate of the third transistor are configured to be applied with a first signal and a second signal so that the non-inverted video signal and the inverted video signal are applied to the pixel portion, wherein the first signal serves as a first high power supply potential and a first low power supply potential in the first period, wherein the second signal serves as a second high power supply potential and a second low power supply potential in the second period, wherein the first high power supply potential is higher than the second high power supply potential, and wherein the first low power supply potential is higher than the second low power supply potential.
