Array substrate and display device

Abstract

The present disclosure provides an array substrate and a display device. The array substrate includes a substrate layer and a gate drive circuit disposed at a peripheral region of the substrate layer. The gate drive circuit includes a plurality of cascaded shift registers. The shift register includes an input circuit, an output circuit, a pull-down node control circuit, and a noise reduction circuit. At least one transistor included in the input circuit, the output circuit, and the noise reduction circuit is a first type of transistor. The pull-down node control circuit includes a plurality of transistors connected between a first voltage terminal and a first reset voltage terminal, and at least one transistor of the plurality of transistors is a second type of transistor. The first type of transistor includes a first active layer, and the second type of transistor includes a second active layer. An electron mobility of the second active layer is less than an electron mobility of the first active layer.
