1. A display device comprising:
a substrate comprising a main area and a subsidiary area protruding from one side of the main area, the main area comprises a display area in which a plurality of emission areas is arranged in a first direction and a second direction, and a non-display area disposed around the display area;
a circuit array layer disposed on the substrate, wherein the circuit array layer comprises a plurality of pixel drivers associated with the plurality of emission areas, respectively, data lines which transmit data signals to the plurality of pixel drivers, and demux circuits disposed in a demux area of the non-display area, wherein the demux area is disposed adjacent to the subsidiary area; and
a display driver circuit disposed in the subsidiary area of the substrate, wherein the display driver circuit supplies data driving signals associated with the data lines,
wherein one demux circuit of the demux circuits outputs two or more data signals based on one data driving signal of the data driving signals supplied by the display driver circuit,
wherein the demux circuits comprise a first demux circuit disposed in a first demux area of the demux area which is adjacent to the subsidiary area, and a second demux circuit disposed in a second demux area of the demux area which is adjacent to one side of the first demux area in the first direction,
wherein the circuit array layer further comprises:
a first data input line extending from the subsidiary area to the first demux area and electrically connected to an input terminal of the first demux circuit; and
a second data input line electrically connected to an input terminal of the second demux circuit, and
wherein the second data input line comprises:
a main input line extending from the subsidiary area to the first demux area;
a demux detour line disposed in the display area and electrically connected to the main input line; and
a detour additional line disposed in the second demux area and electrically connected between the demux detour line and an input terminal of the second demux circuit.
