ABSTRACT:
A liquid crystal display device is formed wherein pattern defects generated during the process are eliminated to reduce the need for repairs. In the device, a trench-shaped hole is defined by patterning a passivation layer and a gate-insulating layer at the peripheries of a gate line and a data line to expose a transparent substrate. Accordingly, a protruding defect portion at the pixel area caused by pattern defects in the semiconductor layer and the gate line is removed by the trench-shaped holes defined by patterning the passivation layer and the gate insulating layer at the peripheries of the gate line and the data line, so that a separate repair process is not required.
