    Abstract: A display device includes a first scan line spaced apart from a signal transmission region and a second scan line having a portion that is adjacent to the signal transmission region. The second scan line adjacent to the signal transmission region bypasses the signal transmission region. A compensation signal line connects one end of the second scan line and the other end thereof, and results in a decrease in a combined resistance of the second scan line.

    Abstract: A gate driving circuit includes a pull-up control part, a pull-up part, a carry part, a first pull-down part and a second pull-down part. The pull-up control part applies a carry signal from a previous stage to a first node. The pull-up part outputs an N-th gate output signal based on a clock signal. The carry part outputs an N-th carry signal based on the clock signal in response to the signal applied to the first node. The first pull-down part includes a plurality of transistors connected to each other in series. The first pull-down part pulls down a signal at the first node to a second off voltage in response to a carry signal of a next stage. The second pull-down part pulls down the N-th gate output signal to a first off voltage in response to the carry signal of the next stage.
