1. A display substrate, comprising:
a base substrate;
a plurality of gate lines and a plurality of data lines on the base substrate, wherein each gate line extends in a row direction, each data line extends in a column direction, and the plurality of gate lines and the plurality of data lines intersect to surround a plurality of pixels;
a first thin film transistor and a second thin film transistor in each pixel on the base substrate, wherein each of the first thin film transistor and the second thin film transistor comprises a first electrode and a second electrode; and
a pixel electrode in each pixel on the base substrate, wherein the pixel electrode comprises a pixel conductive layer, the first electrode is located in a layer different from a layer where the pixel conductive layer is located, and the second electrode is located in a layer different from the layer where the pixel conductive layer is located,
wherein the first electrode of the first thin film transistor is electrically connected to the pixel conductive layer of the pixel electrode, the second electrode of the first thin film transistor is electrically connected to the first electrode of the second thin film transistor, and the second electrode of the second thin film transistor is electrically connected to the data line; and
wherein an orthographic projection of a combination of the second electrode of the first thin film transistor and the first electrode of the second thin film transistor on the base substrate at least partially overlaps with an orthographic projection of the pixel conductive layer of the pixel electrode on the base substrate.
