    Abstract: Provided are a shift register and display apparatus including the same. A shift register includes a plurality of stages, each of the plurality of stages including: a node controller configured to: periodically discharge a first node voltage generated from a first driving voltage during a first voltage level of a clock signal, and control a second node voltage opposite to the first node voltage based on a second driving voltage, and an output part configured to receive the clock signal to output an output signal based on the first node voltage.

    Abstract: Disclosed is a display apparatus including a gate driving circuit, which stably holds an output signal during a touch sensing period. The display apparatus includes a display panel including a display area including a plurality of gate lines, a plurality of data lines, and a plurality of touch sensors, a gate driving circuit dividing the display area into a plurality of horizontal blocks and driving gate lines of a horizontal block by units of horizontal blocks at every display period in one frame, and a touch driving circuit sensing a touch through touch sensors of the horizontal block by units of horizontal blocks at every touch sensing period in the one frame. The gate driving circuit includes a plurality of driving stage groups each including a plurality of driving stages supplying a scan pulse to gate lines included in a corresponding horizontal block at every display period and a plurality of holding stage groups each including at least one holding stage supplying a carry signal to a rear driving stage group according to a voltage of a first control node and a voltage of a second control node based on first and second node control powers and an output signal supplied from a front driving stage group, the plurality of holding stages being disposed between the plurality of driving stage groups. Each of the first and second node control powers includes an alternating current (AC) voltage.
