Abstract:
1. A method of manufacturing an array substrate for a liquid crystal display device, comprising: depositing a reflective conductive material layer having a first thickness on a substrate; depositing a transparent conductive material layer having a second thickness on the reflective conductive material layer under a condition of H forming a photoresist pattern on the transparent conductive material layer; performing a first etching process to the transparent conductive material layer and the reflective conductive material layer using the photoresist pattern as an etching mask, wherein the transparent conductive material layer has a first etch bias being larger than a second etch bias of the reflective conductive material layer such that top peripheral surfaces of the reflective conductive material layer is exposed; and performing a second etching process to the reflective conductive material layer using the etched transparent conductive material layer as an etching mask, thereby forming double-layered pixel and common electrodes.
