Abstract
A pixel circuit, a display substrate and a display device are disclosed. The pixel circuit includes: a threshold compensation transistor, a shielding element including a first shielding portion and a second shielding portion coupled with each other; a data writing transistor, orthographic projections of an active layer of the data writing transistor and the gate of the data writing transistor on the substrate are overlapped to form a first overlapping area; the first electrode and the active layer of the data writing transistor are in a same layer, orthographic projections of the first electrode of the data writing transistor and the second shielding portion on the substrate are overlapped to form a second overlapping area; a size of the second overlapping area in the first direction is smaller than that of the first overlapping area in the first direction.
