Abstract:
1. A method of manufacturing an array substrate for a liquid crystal display device, comprising: forming a gate line, a gate pad and a gate electrode on a substrate; forming a gate insulating layer on the gate line, the gate electrode and the gate pad; forming an active layer on the gate insulating layer; forming an ohmic contact layer on the active layer; forming a metal pattern having an island shape over the gate line; forming a data line, a data pad, and source and drain electrodes on the ohmic contact layer; forming a pixel electrode on the source and drain electrodes, the pixel electrode directly contacting the drain electrode and at least an upper surface of the metal pattern without a contact hole; forming a first passivation layer on the substrate including the pixel electrode; forming a second passivation layer on the first passivation layer, the second passivation layer exposing the first passivation layer over the gate pad and the data pad; and patterning the first passivation layer exposed by the second passivation layer to expose the gate pad and the data pad, wherein the active layer, the ohmic contact layer, the data line, the data pad, the source electrode and the drain electrode are formed by one photolithography process.
