Abstract
Embodiments of the application provide a gate driver on array (GOA) circuit and a display apparatus, which is capable of outputting signals of negative pulse waveforms using a simplified circuit design and improving output capability of the GOA circuit by changing a high voltage level of a clock signal to a voltage level of a first high level signal. Thus, the GOA circuit is improved by the first capacitor and the second capacitor, which make the GOA circuit more stable.
