Pixel and display device having the same

A pixel comprising:

• a light emitting element;
• a first node connected to a first driving power source;
• a second node connected to an anode electrode of the light emitting element;
• a first transistor connected between the first node and the second node and having a gate electrode connected to a third node;
• a second transistor connected between a data line and the first node, the second transistor to be turned on by a first scan signal applied through a first scan line;
• a third transistor connected between the second node and the third node, the third transistor to be turned on by a second scan signal applied through a second scan line;
• a fourth transistor connected between the third node and a first initialization power source, the fourth transistor to be turned on by a third scan signal applied through a third scan line;
• a first capacitor connected between the first driving power source and the third node;
• and
• a second capacitor having an input electrode and an output electrode, and connected to the third node through the output electrode to boost a voltage of the gate electrode of the first transistor in response to change in a voltage of the input electrode.
