Abstract: A design for a scan driver and a display device including the scan driver that is more resilient to electrostatic discharge. Thin film transistors within a stage are designed differently depending on whether or not a gate of the transistor is connected to an external source. Transistors whose gate is connected to an external source is specially designed to withstand electrostatic discharge applied to the gate thereof by one or more of increasing a number of channel areas, decreasing a length of an ohmic bridge, including a resistive element to the gate, decreasing a width of a channel areas, and increasing a width of the active layer.

Abstract: A display device comprises a substrate including a display area including light emission areas, and a non-display area disposed adjacent to the display area, a circuit layer disposed on the substrate, and an element layer disposed on the circuit layer, and including light emitting elements disposed in the light emission areas. The circuit layer includes emission pixel drivers electrically connected to the light emitting elements, and gate lines electrically connected to the emission pixel drivers. The gate lines are disposed in a first gate conductive layer on a first gate insulating layer overlapping a semiconductor layer. The gate lines include first gate lines, each of which includes an extension portion extended to the non-display area and disposed in the non-display area. An extension length of the extension portion is equal to or greater than a width of the emission pixel driver in the first direction.
