Abstract
A display substrate and a display device. The display substrate comprises a display area and a non-display area located on at least one side of the display area, and comprises: a base substrate, and pixel driving circuits arranged in an array, a plurality of scanning signal lines, and a plurality of light-emitting signal lines that are arranged in the display area. At least one pixel driving circuit comprises: a writing transistor, a reset transistor, a compensation transistor, and a light-emitting transistor. A control electrode of at least one of the writing transistor, the reset transistor and the compensation transistor in at least one pixel driving circuit is electrically connected to at least one scanning signal line. The light-emitting transistor in at least one pixel driving circuit is electrically connected to at least one light-emitting signal line. At least one scanning signal line among the plurality of scanning signal lines and at least one light-emitting signal line among the plurality of light-emitting signal lines are arranged in different layers.
