The display region includes sub-pixel regions. The display substrate further includes: a base, and organic light-emitting diodes and a first power supply line all on the base. The organic light-emitting diodes are provided in the sub-pixel regions, respectively. A cathode of each organic light-emitting diode extends from the display region to the peripheral region and is connected to the first power supply line in the peripheral region. The first connection side includes a first connection region corresponding to a position between two adjacent pad regions, and a second connection region other than the first connection region. A connection region between the first power supply line and the cathode covers at least part of the second connection region.
