Patent ID: 8648782

Claim:
A display device comprising: a plurality of signal lines; a plurality of scanning lines; a plurality of electric charge supply lines; a plurality of pixels, each of the pixels including a first transistor, a first capacitor, a second capacitor, and a second transistor; wherein a gate terminal of the first transistor and a gate terminal of the second transistor are electrically connected to one of the scanning lines, and one of a source terminal and a drain terminal of the first transistor is electrically connected to one of the signal lines, wherein a first electrode of the first capacitor is electrically connected to the other of the source terminal and the drain terminal of the first transistor, wherein a first electrode of the second capacitor is electrically connected to the first electrode of the first capacitor, wherein one of a source terminal and a drain terminal of the second transistor is electrically connected to a second electrode of the first capacitor, and the other of the source terminal and the drain terminal of the second transistor is electrically connected to one of the electric charge supply lines, and wherein the second electrode of the first capacitor is electrically floating whenever the first transistor is in an off state.
