Abstract:
1. A method of manufacturing an array substrate of a transflective liquid crystal display (LCD), comprising: sequentially forming a transparent conductive layer and a first metal layer on a substrate; defining the first metal layer and the transparent conductive layer to allow the first metal layer to form complementary patterns of a gate electrode, a first conducting wire, a capacitance line and a penetrating region of a pixel region, and to allow the transparent conductive layer to form a pixel electrode; sequentially forming a first passivation layer and a second metal layer on the substrate; defining the second metal layer to form the gate electrode, the first conducting wire and the capacitance line, wherein the capacitance line, and the first passivation layer and the transparent conductive layer constitute a storage capacitance; forming a dielectric layer on the substrate; removing the dielectric layer and the second metal layer on a penetrating region of the pixel region, the first passivation layer on sides of the penetrating region, and the dielectric layer and the first passivation layer surrounding an end of the first conductive line simultaneously; forming a channel region on the dielectric layer on the gate electrode; forming a third metal layer on the substrate; defining the third metal layer to form a second conductive line, a source electrode and a drain electrode, wherein the source electrode and the drain electrode are at two sides of the channel region, and the drain electrode is electrically connected to the transparent conductive layer; forming a second passivation layer on the substrate; and defining the second passivation layer and the first passivation layer to remove the second passivation layer and the first passivation layer on the penetrating region on the pixel region.
