Pixel circuit and display device including same

A display device comprising:

• a display panel including a plurality of data lines, a plurality of gate lines intersecting the plurality of data lines, and a plurality of pixel circuits,
• wherein each of the plurality of pixel circuits includes:
• a driving element including a first electrode connected to a first power line, a gate electrode connected to a first node, and a second electrode connected to a second node;
• a switch element configured to supply a data voltage to the first node in response to a gate signal;
• a capacitor connected between the first node and the second node;
• and
• a first light-emitting element and a second light-emitting element connected in parallel between the second node and a second power line,
• wherein the first light-emitting element and the second light-emitting element are configured to emit a same color of light,
• wherein a first threshold voltage of the first light-emitting element is smaller than a second threshold voltage of the second light-emitting element, based on the first light-emitting element having a different stack structure than the second light-emitting element or an organic light-emitting layer in the first light-emitting element having different composition materials than an organic light-emitting layer in the second light-emitting element, and
• wherein the driving element is configured to supply a driving current to only the first light-emitting element at a first voltage level of the data voltage, and supply the driving current to both the first light-emitting element and the second light-emitting element at a second voltage level of the data voltage higher than the first voltage level.
