In an exemplary embodiment, the other one of the first distance and the second distance is constant along the other one of the first and second portions of the wire in the direction toward the center of the substrate.

In an exemplary embodiment, the second distance alternates between the first value and the second value along the second portion of the wire in the direction toward the center of the substrate.

In an exemplary embodiment, a third distance between the first end of the first insulating layer and the second end of the second insulating layer in an outer area of the wire is about equal to the first distance.

In an exemplary embodiment, a greater value between the first value and the second value is greater than the other one of the first distance and the second distance.

In an exemplary embodiment, a greater value between the first value and the second value is equal to or greater than about 5 μm.

In an exemplary embodiment, a greater value between the first value and the second value is equal to or greater than about 10 μm.

In an exemplary embodiment, a part of the first end of the first insulating layer is bent and crosses the second portion of the wire, and has a first curvature radius. Further, a part of the second end of the second insulating layer is bent and crosses the second portion of the wire, and has a second curvature radius.
