Display device for reducing deterioration of light-emitting elements

A display device comprising:

• pixels arranged along rows and columns, and comprising:
• light-emitting elements;
• a first transistor for supplying a driving current to the light-emitting elements;
• a second transistor for supplying a data voltage to a first node at a gate electrode of the first transistor upon receiving a scan write signal of a gate high level during a first period;
• a third transistor for electrically connecting a second node, which is at a first electrode, and a sensing line upon receiving a first scan sensing signal of a gate high level during the first period and during a second period after the first period;
• and
• a fourth transistor for electrically connecting a third node, which is at a second electrode, and the sensing line upon receiving a second scan sensing signal of a gate high level during a third period after the second period;
• and
• a display driver for driving the pixels, for sensing voltages of the second node and the third node to calculate a driving voltage across the light-emitting elements, and for compensating for the data voltage in case that the driving voltage exceeds a reference voltage.
