ABSTRACT:
A fabricating method of an array substrate for a transflective liquid crystal display device includes: forming a gate electrode and a gate line on the substrate; depositing a first insulating layer on the gate electrode and the gate line; forming an active layer on the first insulating layer over the gate electrode; forming an ohmic contact layer on the active layer; forming source and drain electrodes on the ohmic contact layer, and a data line connected to the source electrode, the data line defining a pixel region with the gate line; depositing a second insulating layer on the source and drain electrodes, and the data line, the second insulating layer having an inorganic material; forming a reflective plate on the second insulating layer at the pixel region, the reflective plate having a transmissive hole; forming a third insulating layer on the reflective plate; and forming a pixel electrode on the third insulating layer at the pixel region, the pixel electrode being transparent and connected to the drain electrode.
