Patent ID: 8054395

Claim:
A method for fabricating a liquid crystal display device, comprising: providing a first substrate divided into a pixel part and data and gate pad parts; depositing a first conductive film on the first substrate to form a gate electrode and a gate line at the pixel part of the first substrate through a first masking process; forming an insulating layer on the entire first substrate including the gate electrode and the gate line; forming an active pattern and source/drain electrodes at the pixel part of the first substrate and forming a data line crossing the gate line to define a pixel area through a second masking process; forming a passivation layer on the entire first substrate; forming first to third photosensitive film patterns having a first thickness and a fourth photosensitive film pattern having a second thickness on the passivation layer through a third masking process; selectively removing a portion of the passivation layer using the first to fourth photosensitive film pattern as a mask to form a first contact hole exposing a portion of the drain electrode; removing the fourth photosensitive film pattern and simultaneously forming fifth to seventh photosensitive film patterns having a third thickness; removing a portion of the passivation layer using the fifth to seventh photosensitive film patterns as masks to form a passivation layer with a thinner thickness than a thickness of an original passivation layer; forming a transparent conductive film on the entire surface of the first substrate; forming at least one crack on the conductive film by heat treating the first substrate; removing the fifth to seventh photosensitive film patterns and simultaneously removing the transparent conductive film on the fifth to seventh photosensitive film patterns to form a pixel electrode electrically connected to the drain electrode via the first contact hole; and attaching the first substrate and a second substrate to each other using a sealant applied to outer edges of the substrates.
