Patent ID: 8552430

Claim:
A thin-film transistor array substrate comprising: a thin film transistor disposed on a substrate, wherein the thin film transistor comprises an active layer, a gate electrode, and source and drain electrodes; a capacitor comprising i) a lower electrode disposed on the same layer as the active layer and ii) an upper electrode disposed on the same layer as the gate electrode; a pixel electrode disposed on the same layer as the gate electrode and the upper electrode, wherein the pixel electrode is electrically connected to at least one of the source and drain electrodes; a first insulating layer disposed between the active layer and the gate electrode and between the lower and upper electrodes of the capacitor, wherein at least a portion of the lower electrode is not covered by the first insulating layer; a second insulating layer disposed between the first insulating layer and the source and drain electrodes, wherein at least a portion of the upper and lower electrodes is not covered by the second insulating layer; and a third insulating layer substantially covering the source and drain electrodes and the upper electrode, wherein at least part of the pixel electrode is not covered by the third insulating layer.
