1. A display device comprising:
a substrate;
a thin-film transistor arranged on the substrate and including a semiconductor layer and a gate electrode overlapping at least a portion of the semiconductor layer;
a pixel electrode arranged on the substrate;
a node connection line separate from the pixel electrode and disposed on a different layer than the gate electrode and configured to connect the thin-film transistor and the pixel electrode to each other; and
an initialization voltage line arranged on the substrate and extending in a first direction,
wherein the node connection line includes a repair portion overlapping the initialization voltage line in a plan view,
wherein an interlayer insulating layer covers the gate electrode, and the node connection line is disposed on an opposite surface of the interlayer insulating layer to a surface of the interlayer insulating layer contacting the gate electrode, and
wherein the pixel electrode contacts an emission layer and is disposed between the node connection line and the emission layer in a direction perpendicular to the substrate.
