1. An LCD device comprising:
a gate line and a gate pad on a substrate;
a gate insulating layer on an entire surface of the substrate including the gate line except the gate pad;
a data line and a data pad on the gate insulating layer;
a thin film transistor at a crossing portion of the gate line and the data line;
a passivation layer on the entire surface of the substrate including the thin film transistor except the gate pad and data pad;
an overcoat layer on the passivation layer;
a pixel electrode in contact with the thin film transistor through a contact hole formed in the passivation layer and the overcoat layer;
a first transparent conductive layer directly on an open region of the gate pad to an edge thereof, wherein the first transparent conductive layer is formed at a region where all the gate insulating layer, the a passivation layer and the overcoat layer is removed on said open region including to said edge; and
a second transparent conductive layer directly on an open region of the data pad to an edge thereof, wherein the second transparent conductive layer is formed at a region where all the a passivation layer and the overcoat layer is removed on said open region including to said edge, wherein a semiconductor layer is below the data pad.
