Patent ID: 7450200

Claim:
An array substrate for a transflective liquid crystal display device, the substrate comprising; a thin film transistor including an active layer, a gate electrode and source and drain electrodes, formed sequentially on a substrate; a gate line including connected to the gate electrode; a gate pad at a first end of the gate line; a storage line parallel to the gate line and spaced apart from the gate line; a data line defining a pixel region by crossing the gate line, the data line being connected to the source electrode, wherein the pixel region is divided into a reflection area and a transmission area; a data pad at one end of the data line; an organic insulating layer over the thin film transistor and the data line; a barrier layer on the organic insulating layer, the barrier layer being formed of an inorganic insulating material; a reflector on the barrier layer, the reflector being located in the reflection area; an inorganic insulating layer on the reflector; and a transparent pixel electrode on the inorganic insulating layer, the pixel electrode contacting the drain electrode, wherein the pixel electrode is located in the reflection area and the transmission area.
