Display substrate and display device

The invention discloses a display substrate and a display device. In the display substrate, a plurality of gate driving structures comprise a plurality of straight-edge gate driving structures and a plurality of round-corner gate driving structures, each straight-edge gate driving structure comprises a first output end, and each round-corner gate driving structure comprises a second output end; a plurality of first output ends of the plurality of straight-side gate driving structures are connected with the plurality of first signal lines through the plurality of first connecting structures, and a plurality of second output ends of the plurality of fillet gate driving structures are connected with the plurality of second signal lines through the plurality of second connecting structures; each first connecting structure comprises a first conductive part and a plurality of via hole connecting structures, each second connecting structure comprises a second conductive part and a plurality of via hole connecting structures, and the first conductive parts and the second conductive parts are located on the same conductive layer; and the number and the type of the via hole connecting structures in each first connecting structure are the same as the number and the type of the via hole connecting structures in each first connecting structure. Therefore, the display substrate can effectively reduce the risk of abnormal display of the display substrate.
