Patent ID: 8253916

Claim:
An LCD device comprising: first and second substrates facing each other; gate and data lines on the first substrate defining a pixel region; a thin film transistor comprising: 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 disposed over a predetermined portion of the gate line; at least one passivation layer disposed over the data line and the metal pattern, the passivation layer having a contact hole exposing the drain electrode and a storage hole exposing the metal pattern, wherein the at least one passivation layer comprises an organic insulating layer; a pixel electrode disposed on the pixel region over the contact hole and the storage hole; a column spacer configured to contact the pixel electrode in the storage hole for reducing instantaneous light leakage when a touch is laterally applied to one of the first substrate and the second substrate; and a liquid crystal layer between the first and second substrates, wherein the at least one passivation layer has a thickness of about 2 μm to 3 μm and a cell gap of the liquid crystal layer is about 3 μm to 5 μm, wherein a width of the storage hole is a critical dimension corresponding to a value obtained by adding a critical dimension of the column spacer to a bonding margin, the bonding margin being laterally about 4 μm to 5 μm and wherein a depth of the storage hole defined by removing the at least one passivation layer on the metal pattern is about ½˜1 time of the cell gap of the liquid crystal layer.
