Abstract: A gate driving circuit and a display apparatus including the same are disclosed, in which a plurality of gate lines may be driven through one stage circuit. The gate driving circuit includes first to mth stage circuits outputting a plurality of scan signals by dividing the scan signals into a first signal group and a second signal group. The first to mth stage circuits are grouped into k number of stage groups having two adjacent stage circuits, stage circuits of jth stage group (j is a natural number of 1 to k−1) output the scan signals of the first signal group to be earlier than the scan signals of the second signal group, and stage circuits of (j+1)th stage group output the scan signals of the second signal group to be earlier than the scan signals of the first signal group.

Abstract: According to embodiments of the disclosure, a gate driving circuit and a display device may include four buffer groups for driving 4k scan lines, two common logic units for controlling the four buffer groups, and a common sensing circuit controlling to output a sensing driving scan signal to at least one scan line among the 4k scan lines. Thus, it is possible to allow the gate driving circuit to have a low-area structure and to reduce the bezel area of the display device.
