Patent ID: 8049702

Claim:
A display device comprising: a first substrate; a second substrate; a plurality of pixel electrodes formed on the first substrate; a first switching element supplying a video signal to the pixel electrode; a video signal line supplying a video signal to the first switching element; and a scanning signal line supplying a scanning signal which controls the first switching element, wherein an inverter circuit electrically connects between the switching element and the pixel electrode and inverts a voltage of the pixel electrode by a voltage held in the pixel electrode before inverting, a second switching element electrically connects between an output of the inverter circuit and the pixel electrode, a third switching element electrically connects between the pixel electrode and an input of the inverter circuit, the third switching element electrically connects the first switching element and the pixel electrode, the video signal is supplied by the first switching element and the third switching element to the pixel electrode, the voltage of the pixel electrode is transmitted from the pixel electrode to the inverter circuit through the third switching element when the third switching element is in an on state and the second switching element is in an off state, the second switching element includes a parallel-connected N-type transistor and a P-type transistor, and the third switching element includes a parallel-connected N-type transistor and a P-type transistor.
