Display device having plurality of initialization power sources

A display device to operate in a unit of a first period when displaying first images at a first frequency and operate in a unit of the first period and at least one second period when displaying second images at a second frequency lower than the first frequency, the display device comprising:

• pixels;
• a scan driver to supply a first scan signal, a second scan signal, and a third scan signal;
• an emission driver to supply an emission control signal;
• a power supply to supply a first initialization voltage to a first initialization power line,
• wherein at least one of the pixels comprises:
• a first transistor connected between a first node and a second node and having a gate electrode connected to a third node;
• a second transistor connected between a data line and the first node and having a gate electrode to receive the first scan signal;
• a third transistor connected between the second node and the third node and having a gate electrode to receive the second scan signal;
• a fourth transistor connected between the first node and the first initialization power line or between the second node and the first initialization power line, and having a gate electrode to receive the third scan signal;
• and
• a fifth transistor connected between a first power source and the first node and having a gate electrode to receive the emission control signal;
• a sixth transistor connected between the second node and a fourth node, and having a gate electrode to receive the emission control signal;
• and
• a light emitting element having a first electrode connected to the fourth node and a second electrode connected to a second power source,
• wherein the first to third scan signals are toggled in the first period when the first images are displayed at the first frequency, and
• wherein the first to third scan signals are toggled in the first period and the third scan signal is toggled in the second period when the second images are displayed at the second frequency.
