Abstract:
An array substrate for a transflective liquid crystal display device, comprising:a substrate; a thin film transistor formed on the substrate and having gate, source and drain electrodes; a first passivation layer covering the thin film transistor and having a first contact hole exposing the drain electrode; a transparent electrode formed on the first passivation layer and connected with the drain electrode through the first contact hole; a second passivation layer formed on the transparent electrode and having a second contact hole exposing the transparent electrode over the first contact hole; and a reflective electrode formed on the second passivation layer, connected with the transparent electrode through the second contact hole and having a first transmissive hole, wherein the first and second passivation layers have different thicknesses and an area exposed by the contact hole in the thicker passivation layer is less than an area exposed by the contact hole in the other passivation layer.
