摘要： A display substrate includes a plurality of pixel units arranged to form a plurality of pixel columns extending along a first direction, the display substrate further includes a plurality of groups of power source signal lines and pixel driving circuits located on the substrate, each group of power source signal lines includes a plurality of secondary signal lines, the pixel driving circuits of the pixel units in each pixel column are connected to different secondary signal lines in a same group of power source signal lines, each secondary signal line extends along the first direction from a starting end of the power source signal lines, extension lengths of the secondary signal lines in the same group of power source signal lines are different, and resistance values per unit length of different secondary signal lines along the first direction decrease as total lengths of the secondary signal lines increase.
