摘要:
A gate driving circuit includes N stages (where N is a natural number greater than or equal to 2). The N stages are cascaded, and each of the N stages has a gate line connected thereto. A first stage group includes k stages of the N stages (where k is a natural number less than N), and the first stage group outputs a first output signal in response to a start signal. A second stage group (including N−k stages) generates a second output signal in response to the first output signal and outputs the second output signal to a corresponding gate line. The first stage group includes a first buffer and a second buffer, each of which receives the start signal. A size of the first buffer is smaller than a size of the second buffer.
