1. A pixel circuit comprising:
a first pixel circuit including a first EM transistor to which a pulse of a first EM signal is applied, and a first driving transistor configured to drive a first light emitting element; and
a second pixel circuit including a second EM transistor to which a pulse of a second EM signal is applied, and a second driving transistor configured to drive a second light emitting element,
wherein a node between the first EM transistor and the first driving transistor and a node between the second EM transistor and the second driving transistor are connected,
wherein the first EM transistor is connected between a first power line and the first driving transistor, and responsive to the first EM transistor being turned on, a pixel driving voltage of first power line is supplied to the first driving transistor such that the first driving transistor drives the first light emitting element to emit light,
wherein the second EM transistor is connected between a second power line and the second driving transistor, and responsive to the second EM transistor being turned on, a pixel driving voltage of second power line is supplied to the second driving transistor such that the second driving transistor drives the second light emitting element to emit light, and
wherein the first pixel circuit and the second pixel circuit share a same data line with each other.
