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.
