Abstract
A liquid crystal display device of a lateral electric field type performs display by rotating homogeneous-aligned liquid crystals by a lateral electric field substantially parallel to a substrate, which is applied across a pixel electrode and a common electrode, to increase the aperture ratio of a liquid crystal panel by narrowing the width of a black matrix provided along a data line. A source pixel electrode connected to a source electrode extends along the data line, a storage capacitance electrode formed by the same layer as the data line overlaps an adjacent scan line, the source pixel electrode is disposed so as to be connected to the storage capacitance electrode and a pixel along one side, an interlayer film is formed on the source pixel electrode, and a pixel electrode and a common electrode formed by a transparent conductive film are formed on the interlayer film.
