Pixel and display device having the same

A display device comprising:

• a display panel including a plurality of pixels;
• and
• a panel driver which drives the display panel,
• wherein each of the pixels comprises:
• a first transistor including a gate connected to a first node, a first terminal which receives a first power supply voltage, and a second terminal connected to a second node;
• a second transistor including a gate connected to a third node, a first terminal which receives the first power supply voltage, and a second terminal connected to the first node;
• a third transistor including a gate connected to the second node, a first terminal connected to the first node, and a second terminal which receives a reference voltage;
• a fourth transistor including a gate which receives a first scan signal, a first terminal which receives the first power supply voltage, and a second terminal connected to the third node;
• a fifth transistor including a gate which receives the first scan signal, a first terminal which receives a data voltage, and a second terminal connected to the second node;
• a first capacitor connected between the first node and the third node;
• and
• a light emitting element including a first terminal connected to the second node and a second terminal which receives a second power supply voltage.

A pixel comprising:

• a first transistor connected between a line supplying a power supply voltage and a second node, and which provides a driving current corresponding to a data voltage to a light emitting element based on a voltage of a first node;
• a third transistor connected between the first node and a line supplying a reference voltage, and which generates a sampling current based on a difference between a voltage of the second node and the reference voltage;
• a second transistor connected between the line supplying the power supply voltage and the first node, and which adjusts the voltage of the first node and generates the sampling current based on a voltage of a third node;
• a fourth transistor which transfers the power supply voltage to the third node in response to a scan signal;
• a fifth transistor which transfers the data voltage to the second node in response to the scan signal;
• and
• a capacitor connected between the first node and the third node.
