Claim 12:
13. A display device comprising:
a substrate comprising a main region and a sub-region protruding from one side of the main region, the main region comprising a display area in which a plurality of emission areas are arranged, and a non-display area disposed around the display area;
a circuit array layer disposed on the substrate and comprising:
a plurality of pixel drivers respectively corresponding to the plurality of emission areas,
data lines configured to transmit data signals to the plurality of pixel drivers,
first dummy lines extending in the same direction as the data lines and respectively adjacent to the data lines, and
second dummy lines extending in a first direction intersecting an extension direction of the data lines; and

a light emitting array layer disposed on the circuit array layer and comprising a plurality of light emitting elements respectively corresponding to the plurality of emission areas,
wherein the circuit array layer further comprises:
a bias supply line extending from the sub-region to the non-display area and configured to transmit a bias power,
a first power supply line and a second power supply line extending from the sub-region to the non-display area and configured to transmit a first power and a second power for driving the light emitting elements, respectively, and
data supply lines respectively connecting the data lines to the display driving circuit disposed in the sub-region,

wherein the data lines comprise:
a first data line disposed in a middle region of the display area adjacent to the sub-region in a second direction intersecting the first direction and connected to a first data supply line among the data supply lines;
a second data line disposed in a first side region of the display area in contact with the middle region in the first direction and connected to a second data supply line among the data supply lines; and
a third data line disposed in a second side region of the display area between the first side region and the non-display area,
wherein the first dummy lines comprise:
a first data detour line adjacent to a part of the second data line and connected to a third data supply line among the data supply lines, and
auxiliary lines other than the first data detour line,

the second dummy lines comprise:
a second data detour line connecting the first data detour line to the third data line, and
additional lines other than the second data detour line,

some auxiliary lines of the auxiliary lines and some additional lines of the additional lines are electrically connected to the bias supply line, and
some others of the auxiliary lines and some others of the additional lines are electrically connected to the second power supply line.
