Pixel circuit and display device having the same

A pixel comprising:

• a light emitting element including a first electrode and a second electrode, wherein the first electrode is directly connected to a first power line for supplying a first power voltage;
• a first transistor including a first electrode, a second electrode, and a gate electrode, the first electrode of the first transistor being electrically connected to the second electrode of the light emitting element, the first transistor being configured to control an amount of driving current flowing from the first electrode of the first transistor to a second power line via the second electrode of the first transistor, the second power line for supplying a second power voltage;
• a second transistor including a gate electrode connected to an emission control line and connected between the first electrode of the first transistor and the second electrode of the light emitting element;
• a third transistor connected between the second electrode of the first transistor and the second power line for supplying the second power voltage;
• a fourth transistor including a gate electrode connected to a first scan line and connected between a third power line and the second transistor, the third power line for supplying a third power voltage, the third power voltage being externally supplied to the pixel;
• and
• a first capacitor connected between the gate electrode of the first transistor and the second electrode of the first transistor, the first capacitor being directly connected to each of the gate electrode of the first transistor and the second electrode of the first transistor.
