Pixels, display device comprising pixels, and driving method therefor

A pixel comprising:

• a first transistor electrically connected between a first power source and a fourth node, and including a gate electrode electrically connected to a first node;
• a second transistor electrically connected between a third node and a data line, and turned on in response to a scan signal of a first polarity applied to a first scan line;
• a third transistor electrically connected between the first node and the fourth node, and turned on in response to the scan signal of the first polarity applied to a third scan line;
• a fourth transistor electrically connected between a second node and an initialization voltage, and turned on in response to a scan signal applied to a second scan line;
