Abstract
A liquid crystal display device includes first and second substrates facing each other; a liquid crystal layer between the first and second substrates; a thin-film transistor (“TFT”) on the first substrate and including a semiconductor layer and a gate, source and drain electrodes; an organic layer on the TFT and defining a contact hole therein which exposes a portion of the drain electrode; a conductive layer on the organic layer and contacting the exposed portion of the drain electrode at the contact hole; a common electrode which is on the organic layer and isolated from the conductive layer; a passivation layer on the conductive layer and the common electrode and defining an opening therein which exposes a portion of the conductive layer; and a pixel electrode on the passivation layer and the conductive layer and contacting the exposed portion of the conductive layer at the opening.
