Abstract: The disclosure provides a liquid crystal display panel, an array substrate and a manufacturing method thereof. In the method, controllable resistance spacer layers are formed on at least one of a source doped region and a drain doped region of a low temperature polysilicon active layer, wherein when a turn-on signal is not applied to the gate layer, the controllable resistance spacer layers serve as a blocking action for a flowing current, and when the turn-on signal is applied to the gate layer, the controllable resistance spacer layers serve as a conducting action for the flowing current, such that a contact region formed of the controllable resistance spacer layers is connected the corresponding source layer and the corresponding drain through the controllable resistance spacer layers. Therefore, the disclosure is capable of effectively decreasing a leakage of a thin film transistor.

Abstract: A GOA circuit and an LCD are disclosed. The GOA circuit includes multiple cascaded GOA units and a control module. Each of the multiple cascaded GOA units is used for charging a corresponding horizontal scanning line in a display area through driving of a first stage-transferring clock, a second stage-transferring clock, a first control clock and a second control clock. The control module is used to control the gate driving signals to be reset to the first voltage level, that is an ineffective voltage level, after the GOA circuit finishes a charging for all of the horizontal scanning lines simultaneously through the starting pulse signal such that a redundant pulse signal generated on the horizontal scanning lines before the gate driving signal of the first stage GOA unit is outputted is avoided in order to ensure a normal operation of the GOA circuit.
