1. A display device, comprising:
a substrate;
a plurality of first electrodes disposed in a column direction and a row direction on the substrate; and
a second electrode and a third electrode disposed alternately in the column direction and the row direction on the substrate;
wherein the plurality of first electrodes respectively include:
a first emission region;
a first contact region protruding from the first emission region in a first direction parallel to the column direction, the first contact region overlapping a first contact hole through which the first electrode electrically connecting a first thin film transistor; and
a first dummy region protruding from the first emission region in a second direction opposite to the first direction and parallel to the column direction,
wherein the second electrode includes:
a second emission region;
a second contact region protruding from the second emission region in the second direction, the second contact region overlapping a second contact hole through which the second electrode electrically connecting a second thin film transistor,
wherein the third electrode includes:
a third emission region;
a third contact region protruding from the third emission region in the second direction, the third contact region overlapping a third contact hole through which the third electrode electrically connecting a third thin film transistor.
