Abstract
An LCD device according to the present invention includes having first and second substrates facing each other gate and data lines crossing each other to define a pixel region, a thin film transistor including a gate electrode protruding from the gate line, a source electrode protruding from the data line and a drain electrode spaced from the source electrode at a predetermined interval, a metal pattern over a predetermined portion of the gate line, a passivation layer over the data line and the metal pattern to have a contact hole exposing the drain electrode and a storage hole exposing the metal pattern, a pixel electrode on the pixel region over the contact hole and the storage hole, a column spacer contacting with the pixel electrode through the storage hole and a liquid crystal layer between the first and second substrates.
