Abstract:
A method of fabricating an array substrate for a transflective liquid crystal display device, comprising:forming a gate electrode and a gate line on a substrate through a first mask process; forming a first insulating layer on the gate electrode and the gate line; forming a semiconductor layer on the first insulating layer over the gate electrode through a second mask process; forming source and drain electrodes on the semiconductor layer, a data line crossing the gate line, and a reflective layer on the first insulating layer through a third mask process, the source and drain electrodes being spaced apart from each other, the source electrode being connected to the data line, the gate line and the data line defining a pixel region having a transmissive portion and a reflective portion, the reflective layer being disposed in the pixel region and having a transmissive hole corresponding to the transmissive portion, the source and drain electrodes, the data line and the reflective layer having multiple layers of metal, a top layer of the multiple layers including a reflective metallic material; forming second insulating layer on the source and drain electrodes, the data line and the reflective layer through a fourth mask process, the second insulating layer having a drain contact hole exposing the drain electrode; and forming a pixel electrode on the third insulating layer through a fifth mask process, the pixel electrode including a transparent conductive material, the pixel electrode being connected to the drain electrode through the drain contact hole.
