Abstract:
A liquid crystal display device comprising:a substrate; a thin film transistor over said substrate; a first interlayer insulating film over said thin film transistor; a common electrode having a function of a black matrix over said first interlayer insulating film; a second interlayer insulating film over said common electrode; a pixel line and at least one pixel electrode both formed over the second interlayer insulating film, said pixel electrode extending from said pixel line; and a liquid crystal layer over said pixel line and said pixel electrode; wherein said pixel electrode is electrically connected to the thin film transistor through said pixel line; wherein said liquid crystal layer is driven by an electric field formed between said pixel electrode and said common electrode, said electric field having a component parallel with said substrate; and wherein a storage capacitor is formed between said pixel line and said black matrix.
