1. A display device comprising:
a substrate comprising a display area in which emission areas are arranged, and a non-display area located around the display area;
a circuit layer on the substrate; and
an element layer on the circuit layer, and comprising light emitting elements positioned in the emission areas,
wherein the circuit layer comprises:
light emitting pixel drivers electrically connected to the light emitting elements;
data lines electrically connected to the light emitting pixel drivers;
first auxiliary lines extending in a first direction crossing the data lines and positioned in the light emitting pixel drivers; and
second auxiliary lines extending in a second direction crossing the first direction and in parallel with the data lines, the second auxiliary lines being paired with respective ones of the data lines,
wherein the first auxiliary lines comprise a first bypass auxiliary line electrically connected to a first data line of the data lines that is adjacent to the non-display area in the first direction,
wherein the second auxiliary lines comprise a second bypass auxiliary line paired with a second data line spaced farther from the non-display area than the first data line in the first direction among the data lines,
wherein the circuit layer further comprises:
a first connection auxiliary electrode adjacent to a crossing between the first bypass auxiliary line and the second bypass auxiliary line, and spaced apart from the first bypass auxiliary line;
a first connection line connecting the first bypass auxiliary line to the first connection auxiliary electrode; and
a first auxiliary protrusion electrode protruding from the second bypass auxiliary line, and electrically connected to the first connection auxiliary electrode through an auxiliary connection hole of auxiliary connection holes.
