1. A display device comprising:
a substrate;
a circuit layer disposed on the substrate; and
an element layer disposed on the circuit layer,
wherein the substrate comprises a display area in which emission areas are arranged, and a non-display area disposed around the display area,
the display area comprises a non-emission area between the emission areas, and light sensing areas disposed in the non-emission area,
the element layer comprises light emitting elements disposed in the emission areas and light sensing elements respectively disposed in the light sensing areas, and
the circuit layer comprises:
light emitting pixel drivers electrically connected to the light emitting elements;
light sensing pixel drivers electrically connected to the light sensing elements;
data lines electrically connected to the light emitting pixel drivers;
first dummy lines extending in a first direction intersecting the data lines;
second dummy lines extending parallel to the data lines, each of the second dummy lines paired with one of the data lines; and
a reset control line electrically connected to the light sensing pixel drivers, extending in the first direction, transmitting a reset control signal for resetting the light sensing pixel drivers, and overlapping at least one of the first dummy lines.
