Display substrate and display panel

The invention provides a display substrate and a display panel, and relates to the technical field of display, the display substrate comprises a plurality of sub-pixels, and each sub-pixel comprises a pixel driving circuit and a light emitting device which are electrically connected. The pixel driving circuit comprises a driving module, a first reset module, a second reset module, an input module, a first light-emitting control module, a second light-emitting control module and a compensation module. The pixel driving circuit comprises a plurality of transistors, and each transistor comprises an active part; the display substrate further comprises a plurality of conductive patterns. The orthographic projections of the active parts of all the transistors in at least one sub-pixel on the substrate are located within the orthographic projection of the conductive patterns on the substrate. The display substrate is used for preparing a display panel.
