Display device

A display device comprising:

• a substrate including an active area and a non-active area which surrounds the active area;
• a plurality of circuit films positioned at a first side of the substrate and positioned in the non-active area, the plurality of circuit films spaced apart from one another;
• and
• a first link portion connected to a connection wiring of the plurality of circuit films positioned in the non-active area,
• wherein the first link portion comprises:
• a first metal layer disposed on the substrate;
• a buffer layer covering an upper surface of the substrate and the first metal layer;
• a gate insulating film disposed on the buffer layer;
• a first signal wiring disposed on the gate insulating film;
• a planarization layer covering an upper surface of the buffer layer and the first signal wiring;
• and
• a first link wiring disposed on the planarization layer,
• wherein the first link wiring and the first signal wiring are electrically connected through contact holes and the first signal wiring and the first metal layer are electrically connected through the contact holes.
