Abstract: A display device includes a first active layer disposed on a substrate and including a source area, a resistance area, and a drain area spaced apart from the source area by the resistance area, a first gate electrode and a second gate electrode disposed on the first active layer and overlapping the first active layer, and a first power voltage electrode disposed on the first gate electrode and the second gate electrode and overlapping the resistance area in a cross-sectional view. In this case, the resistance area of the active layer and the first power voltage electrode may form a floating node capacitor. Accordingly, in a case that the first gate electrode and the second gate electrode form a dual gate transistor with the active layer, an instantaneous voltage increase may be suppressed and current leakage may be prevented.
