Pixel circuit and display device including the same

A display device comprising:

• a pixel array in which a plurality of data lines, a plurality of gate lines, and a plurality of pixel circuits are arranged;
• a data driver configured to output a data voltage to the plural data lines;
• and
• a gate driver configured to output a gate signal to the plural gate lines,
• wherein each of the pixel circuits includes:
• a light-emitting element;
• a first driving element to drive the light-emitting element;
• a second driving element to drive the first driving element;
• a capacitor connected to a gate electrode of the second driving element;
• a first switch element configured to apply a data voltage to a second electrode of the capacitor;
• a second switch element configured to apply an off voltage to a first electrode of the capacitor;
• a third switch element connected between the first electrode of the capacitor and a first electrode of the second driving element;
• a fourth switch element configured to apply a pixel ground voltage to the first electrode of the second driving element;
• a fifth switch element configured to apply a pixel driving voltage to a second electrode of the second driving element;
• and
• a sixth switch element connected between the light-emitting element and the first driving element.
