摘要： Provided is a display substrate. In the display substrate, a base substrate includes a display region, a bending region and a pad region. A length of the display region in a first direction is greater than a length of the display region in a second direction. Since the pad region, the bending region and the display region are arranged along the second direction, the pad region is arranged on a side where a long boundary line of the display region is located, such that each signal line led into the display region from the pad region has a relatively short length in the display region.
