Display device

A display device comprising:

• a substrate including a display area;
• and
• a unit driving area disposed in a matrix form in the display area,
• wherein the unit driving area includes a light-emitting element including a first electrode and a second electrode, a column driver configured to drive a column line connected to the first electrode, and a row driver configured to drive a row line connected to the second electrode,
• wherein the column driver is connected to a plurality of column lines and is connected in common to the first electrode of each of light-emitting elements in a same column,
• wherein the row driver is connected to a plurality of row lines and is connected in common to the second electrode of each of light-emitting elements in a same row, and
• wherein the column driver includes:
• a driving transistor including a first gate electrode connected to a first node, a first drain electrode connected to a second node to which a high-potential voltage is applied, and a first source electrode connected to a third node to which a pre-charge voltage is applied;
• a first light-emitting control transistor including a second gate electrode to which a first light-emitting control signal is applied, a second drain electrode connected to the third node, and a second source electrode connected to a fourth node to which a reset voltage is applied;
• and
• a second light-emitting control transistor including a third gate electrode to which a second light-emitting control signal is applied, a third drain electrode to which a high-potential voltage is applied, and a third source electrode connected to the second node.
