Abstract:
1. An array substrate for a liquid crystal display device, comprising: a substrate; a gate electrode on the substrate; a first insulating layer on the gate electrode; an active layer on the first insulating layer and corresponding to the gate electrode; a source electrode over the active layer and overlapping an edge of the active layer and forming a first parasitic capacitance between the source electrode and gate electrode; a drain electrode over the active layer and having an island shape, wherein the drain electrode is enclosed by the source electrode and located entirely on the gate electrode and forms a second parasitic capacitance between the drain electrode and gate electrode; a second insulating layer on the source and drain electrodes, and including a drain contact hole exposing the drain electrode; and a pixel electrode over the second insulating layer and connected to the drain electrode, wherein the source electrode has an opening located in an inner space towards a pixel region.
