Thin Film Transistor Substrate and Display Device Including the Same

Disclosed is a thin film transistor substrate capable of preventing a circuit from being damaged by static electricity, and a display device including the same, wherein the thin film transistor substrate includes a substrate having a display area for displaying an image, and a non-display area. The circuit is disposed in the non-display area. The circuit includes a first electrode, an insulating film on the first electrode, and a second electrode on the insulating film. An edge of the first electrode facing the display area extends beyond an edge of the second electrode facing the display area.
