摘要： A display substrate includes an underlayer substrate and a circuit structure layer. The circuit structure layer is located in a display area of the underlayer substrate. The circuit structure layer includes at least one first circuit area and at least one second circuit area. The first circuit area includes at least one first gate drive circuit; the second circuit area includes at least one second gate drive circuit. The first gate drive circuit is cascaded with the second gate drive circuit. The first gate drive circuit includes a plurality of cascaded first gate drive units, and the second gate drive circuit includes a plurality of cascaded second gate drive units. A plurality of first gate drive units are sequentially arranged in a second direction, and a plurality of second gate drive units are sequentially arranged in the second direction.
