Embodiments of the invention provide an array substrate and a display device, the array substrate comprises a plurality of pixel units arranged in an array and a plurality of shifting register units, each shifting register unit corresponding to a row of pixel units. A shifting register unit corresponding to pixel units of any row comprises: a row shared module outside of a display area of the array substrate, an input of which is connected with clock signal lines and a gate signal line of pixel units of a previous row, and an output of which is connected with a pull-up control signal line of pixel units of the row thereof and a pull-down control signal line of pixel units of the row thereof; an output pull-up module within the display area of the array substrate, which is connected to the pull-up control signal line of pixel units of the row thereof and a gate signal line of pixel units of the row thereof; an output pull-down module within the display area of the array substrate, which is connected to the pull-down control signal line of pixel units of the row thereof and the gate signal line of pixel units of the row thereof. Embodiments of the invention can overcome the problem of the gate driver restricting the narrowing for the frame.
