Abstract
Provided are a display substrate and a display device. The display substrate includes: a base substrate; sub-pixels; light emitting elements; pixel driving circuits; an initialization voltage signal line extending in the first direction; and a control signal line partially extending in the first direction. In a frame of driving the pixel driving circuits of a row of sub-pixels, the control signal controls, in at least one first time period, at least two transistors of the pixel driving circuit to turn on, the initialization voltage signal is provided to the pixel driving circuit in a second time period, and the first and second time periods are separated in timing. An orthographic projection of the initialization voltage signal line on the base substrate overlaps at least partially with that of the control signal line located on a different layer, with an overlapping rate of 60% to 100%.
