1. A display device, comprising:
a substrate comprising:
a main area which comprises:
a display area including emission areas; and
a non-display area disposed around the display area;
a sub-area protruding from a side of the main area;
a circuit layer disposed on the substrate; and
a light emitting element layer disposed on the circuit layer and comprising light emitting elements in the emission areas, wherein
the circuit layer comprises:
pixel drivers corresponding to the emission areas and electrically connected to the light emitting elements;
data lines that transmit data signals to the pixel drivers;
first dummy lines disposed in the display area and extending in a first direction intersecting the data lines; and
second dummy lines extending in a second direction parallel to the data lines and neighboring the data lines on a side in the first direction,
a subset of via holes among via holes through which the first dummy lines and the second dummy lines are electrically connected, overlaps one of the emission areas, and
another subset of via holes are disposed in a non-emission area between the emission areas.
