Abstract
A display substrate, including: a display region and a peripheral region located on the periphery of the display region. A scan driver circuit is disposed in the peripheral region. A plurality of sub-pixels, and a plurality of first signal lines that are connected to the scan driver circuit and extend in a first direction, are disposed in the display region. The display region includes: a substrate, and a semiconductor layer, a first conductive layer, a second conductive layer and a third conductive layer that are sequentially disposed on the substrate. The third conductive layer comprises: a plurality of first signal lines, and first electrodes and second electrodes of a plurality of transistors. An insulating layer between the third conductive layer and the first conductive layer is provided with first via holes.
