1. A display device comprising:
a first driving transistor included in a first subpixel;
a second driving transistor included in a second subpixel adjacent to the first subpixel, and the second driving transistor adjacent to the first driving transistor;
a first shield metal disposed below the first driving transistor;
a second shield metal disposed below the second driving transistor;
a buffer layer disposed on the first shield metal and the second shield metal;
an interlayer insulating film disposed on the buffer layer;
a first source electrode included in the first driving transistor, disposed on the interlayer insulating film, and electrically connected to the first shield metal by a first through-hole in the interlayer insulating film and the buffer layer;
a second source electrode included in the second driving transistor, disposed on the interlayer insulating film, and electrically connected to the second shield metal by a second through-hole in the interlayer insulating film and the buffer layer; and
a welding repair line disposed between the buffer layer and the interlayer insulating film,
wherein the welding repair line comprises a first portion overlapping with at least a part of the first shield metal, a second portion electrically connected to the second source electrode by a third through-hole in the interlayer insulating film, and a third portion disposed between the first portion and the second portion.
