Abstract: There are provided a gate driver and a display device including the same. The gate driver includes: a first scan driver; a first sensing driver; a first scan clock line; and a first sensing clock line. The first scan clock line includes a first scan clock main line extending in one direction, and a first scan clock connection line connected to the first scan clock main line and the first scan driver. The first sensing clock line includes a first sensing clock main line extending in one direction, and a first sensing clock connection line connected to the first sensing clock main line and the first sensing driver. The first scan clock main line is closer to each of the first scan driver and the first sensing driver than the first sensing clock main line.
