Abstract
A GOA circuit and a display panel are provided. The GOA circuit includes N stage GOA units, and an n-th stage GOA unit comprises a forward scan control module, a reverse scan control module, a pull-up module, a pull-down module, and a function module, wherein 2<n<N−1, and n and N are positive integers. The GOA circuit and the display panel can achieve a narrow frame by simplifying a circuit structure, thereby reducing risks during manufacturing process and stability.
