Abstract: A display device includes a display panel including pixels. One of the pixels includes a light emitting diode, a first capacitor connected between a power line receiving a power supply voltage and a first reference node, a first transistor connected between the power line and an anode of the light emitting diode, a second transistor connected between a data line and a first electrode of the first transistor, a third transistor including a plurality of sub-transistors connected between a second electrode of the first transistor and the first reference node in series, and a fourth transistor connected to a second reference node among a plurality of second reference nodes between the sub-transistors and receiving an initialization scan signal.
