Abstract
The present disclosure relates to a gate driving circuit including N number of cascaded-connected GOA driving units, wherein the GOA driving units at each of the levels includes a pull-up control circuit, a pull-up circuit, a level transfer circuit, a boast capacitor, and a pull-down holding circuit. The pull-down holding circuit of the GOA driving unit of the n-th level and the pull-down holding circuit of the GOA driving unit of the (n+1)-th level are turned on alternatedly. The pull-down holding circuit of die GOA driving unit of the n-th level may keep the potential of the node within the GOA driving units at the n-th and the (n+1)-th level in the off state, wherein n=1, 3, 5, . . . , N−1, and N is an even number greater than one. The present disclosure also relates to a LCD including the above gate driving circuit.
