Abstract

An array substrate and a liquid crystal display panel are disclosed. In the array substrate, a shared common electrode and a gate scanning line are disposed on a same layer, and a drain electrode of a third thin film transistor is electrically connected to the shared common electrode by a conductive film layer. Therefore, the shared common electrode only exists in a non-display area between a primary pixel electrode and a sub pixel electrode and does not need to pass the primary pixel electrode and the sub pixel electrode, thereby improving an aperture ratio of pixel electrodes and transmittances.
