Pixel, display device including the pixel, and electronic apparatus including the display device

A display device comprising:

• a display panel including a plurality of pixels;
• a gate driver which provides a write gate signal, a compensation gate signal, and an emission signal to each of the pixels;
• a data driver which provides a data signal to each of the pixels;
• and
• a power management circuit which provides a first power voltage, a second power voltage, and a sustain voltage to each of the pixels,
• wherein each of the pixels comprises:
• a first transistor including a gate connected to a first node, a first terminal connected to a second node, and a second terminal connected to a third node;
• a second transistor which transmits the data signal to the first node in response to the write gate signal;
• a third transistor which transmits the sustain voltage to the third node in response to the compensation gate signal;
• a fourth transistor which transmits the first power voltage to the second node in response to the emission signal;
• a first capacitor connected between the first node and the second node;
• a second capacitor connected between the second node and a power line which transmits the first power voltage;
• and
• a light-emitting element including a first terminal connected to the third node and a second terminal which receives the second power voltage.
