Display device

A display device comprising:

• a substrate;
• a first semiconductor layer on a surface of the substrate;
• a first scan line above the first semiconductor layer;
• a second semiconductor layer above the first scan line;
• a second scan line above the second semiconductor layer;
• a first transistor configured to control a driving current flowing from a first electrode of the first transistor to a second electrode of the first transistor according to a voltage applied to a gate electrode of the first transistor;
• a light-emitting element electrically coupled to the second electrode of the first transistor and configured to emit light according to the driving current;
• a second transistor electrically coupled to the first electrode of the first transistor and configured to transfer a data voltage;
• the first semiconductor layer forming channel regions of the first transistor and the second transistor;
• the first scan line electrically coupled to a gate electrode of the second transistor and extending in a first direction;
• a third transistor configured to supply a voltage to the gate electrode of the first transistor, and including a first electrode electrically coupled to the second electrode of the first transistor and a second electrode electrically coupled to the gate electrode of the first transistor;
• the second semiconductor layer forming a channel region of the third transistor;
• and
• the second scan line electrically coupled to a gate electrode of the third transistor and extending in the first direction,
• wherein the second scan line overlaps the first scan line in a second direction perpendicular to the surface of the substrate,
• wherein the channel region of the third transistor overlaps between the first scan line and the second scan line in the second direction,
• wherein the first scan line is configured to supply a first scan signal to the gate electrode of the second transistor, and the second scan line is configured to supply a second scan signal to the gate electrode of the third transistor, the second scan signal being different from the first scan signal, and
• wherein the first and second scan lines are separately coupled to a scan driver to allow the first scan signal and the second scan signal to be independently supplied to the respective gate electrodes of the second and third transistors.
