Patent ID: 6972825

Claim:
A liquid crystal display comprising: a substrate; a gate wire on the substrate, the gate wire including a gate electrode and gate line; a gate insulating layer covering an exposed surface of the substrate including the gate wire; a thin film transistor formed in an active layer on the gate insulating layer, the thin film transistor having the gate electrode and further having a source electrode and a drain electrode; a data wire on the gate insulating layer, the data wire including a data line, the source electrode, and the drain electrode; a pixel electrode connected to the drain electrode of the thin film transistor; and a passivation layer covering the data wire and the thin film transistor, except the drain electrode, the passivation layer being covered by the pixel electrode, the passivation layer exposing the gate insulating layer except portions of the gate insulating layer where the data wire, the thin film transistor, and pixel electrode are formed; a data pad at an end of the data line, said data pad being covered with the passivation layer; a contact hole in the passivation layer, the contact hole exposing an exposed portion of the data pad; and a data pad covering layer covering the exposed portion of the data pad.
