Abstract:
1. A liquid crystal display panel of a horizontal electric field applying type comprising: a gate line formed on a substrate; a data line crossing the gate line with a gate insulating film positioned therebetween, the crossing of the data line and gate line defining a pixel region; a thin film transistor including a source electrode and a drain electrode formed at the crossing of the gate and data lines; a passivation film for protecting the thin film transistor; a common line overlapped with and insulated from at least one of the gate line and the data line; a plurality of common electrodes connected to the common line, a common electrode of the plurality of common electrodes overlapped with the data line; a pixel electrode connected to the drain electrode, wherein a horizontal electric field is formed between the common electrodes and the pixel electrode; and a storage capacitor substantially parallel with the data line, the storage capacitor including a lower storage electrode on the substrate and connected to the pixel electrode, the gate insulating film formed on the lower storage electrode, and an upper storage electrode on the gate insulating film and connected to at least one of the common electrodes, and being insulated from the lower storage electrode by the gate insulating film, wherein the lower storage electrode and the upper storage electrode overlap with the at least one common electrode, and wherein the lower storage electrode is formed of a same material as the gate line and the upper storage electrode is formed of a same material as the data line.
