a substrate;

an insulating pattern on the substrate;

a first electrode on the substrate and comprising a (1-1)th electrode and a (1-2)th electrode that are spaced from each other and aligned with each other along a first direction;

a second electrode spaced from the first electrode in a second direction different from the first direction, and comprising a (2-1)th electrode and a (2-2)th electrode that are spaced from each other and aligned with each other along the first direction;
