Claim 7:
8. A display device comprising:
a plurality of pixel circuits arranged in a plurality of rows and a plurality of columns;
a gate driving circuit which applies a gate signal to the pixel circuits;
a data driving circuit which applies a data voltage to the pixel circuits;
a control circuit which controls the gate driving circuit and the data driving circuit, and
a plurality of global transistors,
wherein each of the pixel circuits includes:
a first transistor including a first gate terminal, a first source terminal electrically connected to a first node, a first drain terminal electrically connected to a light emitting diode, and a back-gate terminal which receives a first voltage which decreases over time; and
a second transistor including a second gate terminal which receives a gate signal, a second source terminal which receives a data voltage, and a second drain terminal electrically connected to the first node,
wherein each of the global transistors includes a global gate terminal which receives a second voltage that has a negative polarity, a global source terminal which receives a third voltage that has a positive polarity, and a global drain terminal electrically connected to the back-gate terminal,
wherein each of the global transistors is a single gate transistor.
