Abstract:
A pixel including a light emitting element, a first transistor connected between a first node and the light emitting element to control current flowing from a first power supply to a second power supply, a second transistor connected between a data line and the first transistor to be turned on by an ith first scan signal, a third transistor including a P-type TFT connected between the first transistor and the first node to be turned on by the ith first scan signal and, a fourth transistor including an N-type TFT connected between the first node and an initialization power supply line to be turned on by an i−1th scan signal, and a first connection line connected between the third and fourth transistors to electrically connect semiconductor patterns thereof, in which the first connection line is disposed on the third and fourth transistors and contacts the semiconductor patterns thereof.
