Abstract

This disclosure provides a display panel and device. The display panel includes a base substrate, and a gate driving circuit and a selection control line that are disposed on the base substrate, the gate driving circuit includes multiple cascaded shift registers, and each shift register includes a selection unit including a first selection control transistor, a second selection control transistor and a selection control node; the selection control node controls whether a gate driving signal output terminal of the shift register to which the selection control node belongs outputs an active level; a first electrode of the first selection control transistor is coupled to the selection control line, a second electrode of the first selection control transistor is coupled to a first electrode of the second selection control transistor, and a second electrode of the second selection control transistor is coupled to the selection control node; a channel region of the second selection control transistor is greater in length than a channel region of the first selection control transistor.
