Abstract
A display substrate and a display device are provided. A sub-pixel of the display substrate includes a light emitting element and a pixel circuit which includes a first connecting portion, a driving transistor and a threshold compensation transistor, an electrode of the threshold compensation transistor is electrically connected with a gate electrode of the driving transistor through the first connecting portion. The sub-pixel includes a first color sub-pixel pair which includes a first pixel block and a second pixel block. A ratio of an overlapping area between orthographic projections of the second electrode and the first connecting portion of the first pixel block on the base substrate to an overlapping area between orthographic projections of the second electrode and the first connecting portion of the second pixel block on the base substrate is in a range from 0.8 to 1.2.
