A display substrate and a display device. The display substrate (100/600) comprises: a base substrate (101/601), and a pixel circuit (110/610), which is arranged on the base substrate (101/601), the pixel circuit (110/610) comprising a storage capacitor (C), and the storage capacitor (C) comprising a first electrode plate (Cst1) and second electrode plates (Cst2), which are opposite each other. The display substrate (100/600) further comprises a conductive film layer (107/607), wherein the conductive film layer (107/607) comprises a first conductive part (1074/6072). The first conductive part (1074/6072) comprises a main body part (1074a/6072a) and a bridging part (1074b/6072b), wherein the main body part (1074a/6072a) corresponds to the two second electrode plates (Cst2), and the bridging part (1074b/6072b) connects the two second electrode plates (Cst2). The first conductive part (1074/6072) comprises a gap (1074c/6072c) between the two second electrode plates (Cst2), and the provision of the gap (1074c/6072c) can improve pixel transmittance.
