1. A pixel comprising:
an organic light emitting diode;
a first active pattern;
a first-first gate pattern that overlaps a first portion of the first active pattern to form a first transistor, wherein the first portion of the first active pattern includes a curved shape;
a first-second gate pattern that transmits a first scan signal and overlaps a second portion of the first active pattern and forms a second transistor;
a first-third gate pattern that transmits an emission control signal, overlaps a third portion of the first active pattern and forms a fifth transistor, and overlaps a fourth portion of the first active pattern and forms a sixth transistor;
a second-first gate pattern that transmits a first power voltage and overlaps the first-first gate pattern and forms a storage capacitor;
a second-second gate pattern that extends in a first direction and transmits an initialization voltage;
a second active pattern spaced apart from the first active pattern;
a third-first gate pattern that transmits a second scan signal and overlaps a first portion of the second active pattern and forms a third transistor;
a third-second gate pattern that transmits a third scan signal and overlaps a second portion of the second active pattern and forms a fourth transistor; and
a third-third gate pattern that transmits a fourth scan signal and overlaps a third portion of the second active pattern and forms a seventh transistor.
