ABSTRACT:
A liquid crystal display and a method for fabricating the same include a first substrate having an active layer with source/drain regions formed therein, a gate line and a data line extending in directions perpendicular to each other formed thereon, a dummy gate insulating film and a dummy gate electrode both formed on the first substrate in fixed patterns isolated from the gate line, an interlayer insulating film on the first substrate inclusive of the dummy gate electrode with a step, a drain electrode formed on the interlayer insulating film to overlap on upper regions of the dummy gate electrode so as to be in contact with the drain region and have a step to the data line, the data line formed on the interlayer insulating having a step to the drain electrode, a passivation film formed on the interlayer insulating film inclusive of the dummy gate electrode and the data line, a contact hole formed to expose the drain electrode overlapped with the dummy gate electrode, and a pixel electrode overlapping upper edges of the data line and in contact with the drain electrode through the contact hole, thereby reducing a vertical crosstalk while a large aperture is achieved, to improve the picture quality.
