Abstract: A gate driving panel circuit and a display device are discussed. The gate driving circuit in an example includes n gate driving panel circuits configured to output two or more gate signals where, n is a natural number equal to or larger than 2, a start dummy gate driving panel circuit configured to generate a first feedback voltage and transfer a start carry signal to a first gate driving panel circuit among the plurality of gate driving panel circuits, and an end dummy gate driving panel circuit configured to generate a second feedback voltage and transferring an end carry signal to an nth gate driving panel circuit.

Abstract: In an exemplary embodiment of the present disclosure, a thin film transistor including a gate electrode, an active layer, a source electrode, and a drain electrode on a non-pixel area of a substrate includes a first insulating layer that insulates the gate electrode from the source electrode and the drain electrode, and a second insulating layer that covers the source electrode and the drain electrode. According to an exemplary embodiment of the present disclosure, the first insulating layer and the second insulating layer are configured so as not to be extended to a pixel area of the substrate in order to reduce possible oscillation of transmittance depending on a viewing angle which occurs when a specific light of a light source passes through the pixel area.
