Abstract
A display substrate and a display device are provided. The display substrate includes a base substrate, and a shift register unit, a first clock signal line, and a second clock signal line that are provided on the base substrate. The shift register unit includes an input circuit, an output circuit, a first control circuit, a second control circuit, and an output control circuit, and the second control circuit includes a first noise reduction transistor and a second noise reduction transistor; and the input circuit includes an input transistor, the input transistor and the first noise reduction transistor are sequentially arranged in the first direction, and an imaginary line of a channel region of the first noise reduction transistor extending in the second direction does not intersect with an imaginary line of an active layer of the input transistor extending in the second direction.
