Display device

A display device comprising:

• a display panel including a substrate, a display area in which gate lines, data lines and thin film transistors are arranged, and a bezel area located around the display area;
• dummy holes arranged in at least one of the display area and the bezel area;
• an upper dummy electrode disposed in at least one of the dummy holes;
• and
• a lower dummy electrode disposed below the at least one dummy hole and contacting the upper dummy electrode,
• wherein each of the thin film transistors includes:
• a light shield electrode arranged on the substrate;
• an active layer overlapping the light shield electrode and a buffer layer between the light shield electrode and the active layer;
• a gate electrode overlapping the active layer with a gate insulating layer interposed between the active layer and the gate electrode;
• a first source-drain electrode connected to a first connection area of the active layer through a first contact hole in an interlayer insulating layer covering the gate insulating layer and the gate electrode;
• and
• a second source-drain electrode connected to a second connection area of the active layer through a second contact hole in an interlayer insulating layer covering the gate insulating layer and the gate electrode,
• wherein the lower dummy electrode includes at least one of a light shield metal layer which is a same as the light shield electrode, a gate metal layer which is a same as the gate electrode, and a source-drain metal layer which is a same as the first source-drain electrode and the second source-drain electrode.
