1. A display device, comprising:
a display panel including pixels connected to scan lines and data lines, and connection lines, each connected to a corresponding scan line of the scan lines; and
a scan driver which drives the scan lines,
wherein the scan driver comprises:
a scan signal output circuit which outputs a first output signal as a scan signal to a first output line and outputs a second output signal as the scan signal to a second output line;
a signal distribution circuit which outputs the first output signal to a first connection line of the connection lines or a third connection line of the connection lines and output the second output signal to a second connection line of the connection lines or a fourth connection line of the connection lines, in response to a first distribution control signal and a second distribution control signal; and
a scan-off circuit which outputs a gate-off level to at least one of the scan lines in response to a first scan-off control signal and a second scan-off control signal,
wherein the first to fourth connection lines are respectively connected to first to fourth scan lines of the scan lines extending in a first direction,
wherein the first to fourth scan lines are sequentially arranged in a second direction intersecting the first direction,
wherein each of the signal distribution circuit and the scan-off circuit comprises a plurality of transistors, and
wherein the transistors of each of the signal distribution circuit and the scan-off circuit are arranged between the pixels in a display area of the display panel.
