Display device

An electronic device, comprising:

• a display device comprising:
• a substrate comprising a display area comprising emission areas and a non-display area disposed around the display area;
• a circuit layer disposed on the substrate;
• and
• an element layer disposed on the circuit layer,
• wherein the display area comprises a main display area in which the emission areas are arranged side by side, and at least one sub-display area surrounded by the main display area,
• each of the at least one sub-display area further comprises light transmission areas disposed between the emission areas,
• the element layer comprises:
• main light emitting elements disposed in the emission areas of the main display area;
• and
• sub-light emitting elements disposed in the emission areas of the at least one sub-display area, and
• the circuit layer comprises:
• main light emitting pixel drivers electrically connected to the main light emitting elements;
• sub-light emitting pixel drivers electrically connected to the sub-light emitting elements;
• a main anode initialization voltage line disposed in the main display area and configured to transmit a main anode initialization voltage for initializing the main light emitting elements;
• and
• a sub-anode initialization voltage line disposed in the at least one sub-display area and configured to transmit a sub-anode initialization voltage for initializing the sub-light emitting elements, the sub-anode initialization voltage line comprising a first sub-anode initialization voltage line transmitting a first sub-anode initialization voltage to a first plurality of sub-light emitting elements and a second sub-anode initialization voltage line transmitting a second sub-anode initialization voltage to a second plurality of sub-light emitting elements not including any of the first plurality of sub-light emitting elements, wherein the first sub-anode initialization voltage and the second sub-anode initialization voltage have a different voltage level from each other.
