Abstract
A display substrate includes an underlay substrate, a test signal access pin layer, and a signal access pin layer. The underlay substrate includes a display region and a border region at a periphery of the display region. The border region includes a signal access region at one side of the display region and at least one test signal access region adjacent to the signal access region. The test signal access pin layer is in the at least one test signal access region. The signal access pin layer is in the signal access region. A height difference between a surface of the test signal access pin layer away from the underlay substrate and a surface of the signal access pin layer away from the underlay substrate is greater than 0.
