1. A pixel circuit comprising:
a light emitting element including an anode electrode and a cathode electrode, wherein the anode electrode is directly connected to a first power line for supplying a first power voltage;
a driving transistor for controlling an amount of driving current flowing to a second power voltage via the light emitting element, the driving transistor including a first electrode and a second electrode, wherein the first electrode of the driving transistor is electrically connected to the cathode electrode of the light emitting element;
an initialization transistor connected between the second electrode of the driving transistor and an initialization power line for supplying an initialization voltage, the initialization transistor having a gate electrode connected to a first scan line;
a compensation transistor connected between the first power line and the first electrode of the driving transistor, the compensation transistor having a gate electrode connected to a second scan line, wherein the compensation transistor is directly connected to the first power line;
a first emission transistor connected between the cathode electrode of the light emitting element and the first electrode of the driving transistor, the first emission transistor having a gate electrode connected to an emission control line; and
a storage capacitor connected between a gate electrode of the driving transistor and the second electrode of the driving transistor,
wherein a direction in which the driving current flows is a direction from the anode electrode of the light emitting element to the first electrode of the driving transistor.
