Patent ID: 8357937

Claim:
A thin film transistor liquid crystal display (LCD) device comprising: a first substrate divided into a pixel part and first and second pad parts; a gate electrode and a gate line formed at the pixel part of the first substrate, wherein the gate electrode includes a top surface divided into a first region and a second region; an active pattern as an island formed only on the first region of the top surface of the gate electrode, wherein the active pattern includes a top surface having a width smaller than that of the top surface of the gate electrode; a first insulation film formed between the gate electrode and the active pattern, wherein the first insulation film includes a top surface having the same width as that of the top surface of the active pattern; a second insulation film formed on the first substrate and having first and second contact holes exposing source and drain regions of the active pattern, respectively, wherein a portion of the said second insulation film is formed on the second region of the top surface of the gate electrode; source and drain electrodes formed of an opaque conductive material at the pixel part of the first substrate and electrically connected with the source and drain regions of the active pattern via the first and second contact holes; an ohmic-contact layer positioned at lower portions of the source and drain electrodes; a data pad line formed of the opaque conductive material and formed on the second pad part of the first substrate; source and drain electrode patterns formed of a transparent conductive material at upper parts of the source and drain electrodes, wherein the source and drain electrode patterns are respectively patterned in substantially the same form as the source and drain electrodes; a data pad electrode formed of the transparent conductive material to cover the data pad line and electrically connected with the data pad line on the second pad part of the first substrate; a data line formed at the pixel part of the first substrate and crossing the gate line to define a pixel region; an etch stopper as an island positioned between the source and drain electrodes and formed as the second insulation film; a pixel electrode electrically connected with the drain electrode, wherein a portion of the drain electrode pattern extends to the pixel region to form the pixel electrode; and a second substrate attached with the first substrate in a facing manner.
