Abstract
A display substrate and a display device are provided. The display substrate includes a display region and a non-display region at least partially surrounding the display region and including a binding region. A plurality of first pads are located in the binding region, and configured to be electrically coupled to an external electrical test circuitry at a panel test stage, and bound to a circuit board so as to transmit an electric signal from the circuit board to the display region at a display stage. A plurality of second pads are located in the binding region, and configured to be bound to the circuit board so as to transmit the electric signal from the circuit board to the display region at the display stage.
