Claim Text:
1. A liquid crystal display device of a transverse electric field type performing display by rotating horizontal-aligned liquid crystals by a transverse electric field which is applied across a pixel electrode and a common electrode and is substantially parallel to a substrate, comprising: a substrate having a plurality of data lines disposed in parallel and a plurality of scan lines disposed substantially perpendicular to the data lines and in parallel to one another, and having thin film transistors corresponding to respective sub pixels aligned in a matrix surrounded by the data lines and the scan lines and disposed around intersections between the data lines and the scan lines, each of the sub pixels having a short side and a long side; an electric potential supply line extending along each of the data lines and connected to a source electrode of a corresponding thin film transistor in a sub pixel region, the electric potential supply line being formed in the short side of the sub pixel; and at least one storage capacitance electrode continued to the electric potential supply line, the at least one storage capacitance electrode being disposed above each of the respective scan lines via an insulating layer, and generating capacitance between the scan line and itself, wherein the pixel electrode has pixel electrode first parts and a pixel electrode second part, the pixel electrode first parts are disposed in a layer higher than the electric potential supply line in the sub pixel region and linearly formed in substantially parallel to each of the scan lines, the pixel electrode second part is continued to the pixel electrode first parts, formed in parallel to each of the data lines, and connected to the electric potential supply line, the common electrode has common electrode first parts and a common electrode second part, the common electrode first parts are aligned opposed to the pixel electrode first parts, apart from the pixel electrode first parts at same distance, and generate an electric field substantially parallel to the substrate, the common electrode second part is continued to the common electrode first parts and provided above the storage capacitance electrode via an insulating film, and wherein the electric potential supply line and the at least one storage capacitance electrode are continued and formed in a substantially L shape having a vertex near an intersection of each of the data lines and each of the scan lines.
