Patent ID: 7795057

Claim:
A method for fabricating a liquid crystal display (LCD) device comprising: providing a first substrate divided into a pixel part and a pad part; forming a gate electrode and a gate line at the pixel part of the first substrate and a gate pad line at the pad part of the first substrate through a first masking process; forming a first insulation film over the first substrate; forming an active pattern and source and drain electrodes at an upper portion of the gate electrode of the pixel part and a data pad line at the pad part, and forming a data line substantially crossing the gate line to define a pixel region through a second masking process; forming a second insulation film and a first photosensitive film over the first substrate with the active pattern and the source and drain electrodes formed thereon; exposing and developing the first photosensitive film to form a first photosensitive film pattern with a first thickness at a first region of the pixel part and to form second to fourth photosensitive film patterns with a second thickness at a second region excluding the first region and a certain region of an upper portion of the gate/data pad lines of the pad part; selectively removing the first and second insulation films by using the first to fourth photosensitive film patterns as a mask to form a first contact hole exposing a certain region of the gate pad line and a second contact hole exposing a certain region of the data pad line; simultaneously removing the first photosensitive film pattern and a portion of the second to fourth photosensitive film pattern to form fifth to seventh photosensitive film patterns with a third thickness; selectively removing the second insulation film of the first region by using the fifth to seventh photosensitive film patterns as a mask to expose a portion of the drain electrode; forming a third conductive film made of a transparent conductive material over the first substrate on which the fifth to seventh photosensitive film patterns remain; forming a second photosensitive film over the first substrate; removing a portion of the second photosensitive film to expose the third conductive film of the second region; and selectively removing the exposed third conductive film to form a pixel electrode electrically connected directly with the exposed drain electrode at the first region of the pixel part on the first insulation film, a gate pad electrode electrically connected with the gate pad line via the first contact hole at the pad part, and a data pad electrode electrically connected with the data pad line via the second contact hole; and attaching the first substrate and a second substrate.
