    Abstract: A stage circuit including: an output circuit for supplying a voltage of a first or second power supply to an output terminal in response to voltages of first and second nodes; an input circuit for controlling voltages of the second node and a third node; a first signal processor for controlling the voltage of the first node; a second signal processor configured to control the voltage of the first node in response to an output voltage of a third signal processor and a signal supplied to a third input terminal; and the third signal processor for controlling the voltage of the second node. The third signal processor includes: a third capacitor coupled between the first power supply and the second node; and a third transistor coupled between the first power supply and the third input terminal, and including a gate electrode coupled to the second node.

    Abstract: A display device includes a first pixel region including a plurality of first pixels and a plurality of first gate control lines coupled to the first pixels, and a second pixel region spaced apart from the first pixel region. The second pixel region includes a plurality of second pixels and a plurality of second gate control lines coupled to the second pixels. The display device further includes a first non-pixel region disposed between the first pixel region and the second pixel region, and a first coupling line disposed in the first non-pixel region. The first coupling line commonly couples at least two first gate control lines and at least two second gate control lines.
