Abstract
The present invention provides an array substrate and a manufacturing method thereof, and a display panel comprising said array substrate. The array substrate comprises a plurality of pixel units, each of which comprising: a gate formed on a substrate; a gate insulating layer formed on the gate; an active layer being corresponding to the gate and formed on the gate insulating layer; a source and a drain formed on the active layer respectively; a pixel electrode formed on the gate insulating layer and electrically connected to the drain; a passivation layer covering the source, the drain and the pixel electrode; and a common electrode being corresponding to the pixel electrode and formed on the passivation layer, wherein an opening passing through the passivation layer is formed in the common electrode, so as to expose the pixel electrode below the passivation layer.
