1. A liquid crystal display device, comprising:
a liquid crystal display panel having a thin film transistor connected to a gate line and a data line on a substrate, a pixel electrode connected to the thin film transistor, a common electrode for forming a horizontal electric field with the pixel electrode, a common line connected to the common electrode and parallel to the gate line, and a storage line parallel to the gate line, wherein a portion of the storage line and the pixel electrode overlap with at least one insulating film therebetween to form a storage capacitor, and wherein a portion of the pixel electrode crosses the common line to form the storage capacitor with the storage line; a gate driver for supplying a scan pulse to the gate line; a data driver for supplying a pixel voltage signal to the data line; a common driver for supplying a common voltage signal to the common line; and a storage driver for supplying a storage voltage signal to a storage line, wherein the storage capacitor includes a poly silicon type active layer, wherein the storage line is a separate line which is different from the gate line, and wherein the gate line and the common line face each other across a pixel area where the pixel electrode and the common electrode are disposed, wherein the storage line is formed adjacent to the common line, wherein an end portion of the pixel electrode is parallel with the storage line and overlapped with the portion of the storage line, and wherein only the pixel electrode is disposed in a region bounded by the storage line, the common line, and two adjacent data lines.
