Abstract:
1. A thin film transistor (TFT) array substrate, comprising: a TFT disposed on a substrate, the TFT including an active layer, a gate electrode, a source electrode, a drain electrode, a first insulating layer disposed between the active layer and the gate electrode, and a second insulating layer disposed between the gate electrode and the source and drain electrodes; a pixel electrode disposed on the first insulating layer and the second insulating layer, the pixel electrode being connected to one of the source electrode and the drain electrode; a capacitor including a lower electrode disposed on a same layer as the gate electrode, and including an upper electrode including a same material as the pixel electrode, the lower electrode and the TFT being separated from each other without overlapping with each other; a third insulating layer directly disposed between the second insulating layer and the pixel electrode and between the lower electrode and the upper electrode; and a fourth insulating layer that covers the source electrode, the drain electrode, and the upper electrode, and exposes the pixel electrode, wherein the lower electrode has a lower electrode bottom surface directly contacting the first insulating layer, and the gate electrode has a gate electrode bottom surface directly contacting the first insulating layer.
