Abstract: A display panel, a motherboard, and a mini LED display device. The display panel includes: a panel edge extending along a first direction, and a display region and a test region. The test region is between the display region and the panel edge and includes test pads. At least two test pads are arranged along the first direction, adjacent ones of which are spaced by at least two first electrostatic discharge protection wires extending from one side of the display region adjacent to the test region to the panel edge. Each first electrostatic discharge protection wire includes a first line segment located between two adjacent test pads and a second line segment adjacent to the panel edge. A distance between adjacent first line segments between two adjacent test pads in the first direction is less than a distance between adjacent second line segments in the first direction.
