1. A method of fabricating an array substrate for an in-plane switching liquid crystal display device, comprising:

  • forming a common electrode on a substrate using a double layer of a transparent material layer and an opaque material layer, the common electrode including a first transparent conductive material;

    forming a gate line, a gate electrode and a common line on the substrate, the gate electrode being connected to the gate line, the common line contacting the common electrode;

    forming a gate insulating layer on the gate line, the gate electrode and the common line;

    forming an active layer and an ohmic contact layer on the gate insulating layer over the gate electrode;

    forming source and drain electrodes on the ohmic contact layer and a data line connected to the source electrode, the source and drain electrodes being spaced apart from each other;

    forming a passivation layer on the source and drain electrodes and the data line, the passivation layer including a drain contact hole exposing the drain electrode; and

    forming a pixel electrode on the passivation layer, the pixel electrode including a second transparent conductive material and being formed in an alternating pattern with the common electrode, the pixel electrode contacting the drain electrode through the drain contact hole.
