Abstract: Embodiments of the present disclosure are related to a display device, as disposing a clock signal line on an area overlapping with an area where a gate circuit is disposed on a non-active area of a display panel, a gate driving circuit can be disposed on the non-active area while minimizing an increase of the non-active area. Furthermore, as disposing the clock signal line by using metal layers that a first metal layer with a low resistance and a second metal layer with a high reflectance are stacked, the clock signal line disposed on the non-active area and a pixel electrode disposed on an active area can be implemented as a same layer, the clock signal line disposed on the gate circuit can be implemented while reducing the number of masks.
