Patent ID: 7453530

Claim:
A liquid crystal display device comprising: a thin film transistor formed on a substrate, the thin film transistor including a drain electrode, the substrate including: at least one pixel electrode connected to the drain electrode; at least one common electrode, the at least one pixel electrode and the at least one common electrode being formed on a same layer; a gate line and a data line disposed on the substrate to define a pixel, the thin film transistor being formed at an intersection of the gate line and the data line; a common line arranged in parallel with the gate line, the common line being connected to the at least one common electrode; a liquid crystal layer disposed between the substrate and a second substrate opposite to the substrate; and a storage capacitor connected to the drain electrode, the storage capacitor including: a lower capacitor electrode extending from the drain electrode; an upper capacitor electrode; and a protective film between the lower capacitor electrode and the upper capacitor electrode.
