Abstract
A liquid crystal display device includes a thin film transistor formed on a substrate, the thin film transistor including a gate electrode; a gate insulation film formed on the gate electrode and the substrate; and a storage capacitor connected to the drain electrode, the storage capacitor being above the gate insulation film.
Claims30
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.
