Abstract:
A display device includes a display panel including a plurality of pixels. At least one of the pixel includes a light emitting diode, a first transistor connected between a power line receiving a power source voltage and an anode of the light emitting diode, a second transistor connected between a data line and a first reference node, a first capacitor connected between the power line and the first reference node, a second capacitor connected between the first reference node and a second reference node, a third transistor connected between the first reference node and a reference voltage line receiving a reference voltage, a fourth transistor connected between an initialization voltage line receiving an initialization voltage and a drain of the first transistor, and a fifth transistor connected between the drain of the first transistor and the anode of the light emitting diode.
