Patent ID: 7505091

Claim:
A manufacturing method of a liquid crystal display device comprising: forming a thin film transistor-over a substrate; forming a first interlayer insulating film over the thin-film transistor; forming a common electrode as a black matrix over the first interlayer insulating film; forming a second interlayer insulating film so as to cover the black matrix; forming a contact hole through the first and second interlayer insulating films; forming a conductive layer over the second interlayer insulating film, the conductive layer being electrically connected to the thin-film transistor and the conductive layer including at least a first portion which functions as a pixel electrode and a second portion and; forming a liquid crystal layer over the conductive layer, the liquid crystal layer being driven by an electric field formed between the pixel electrode and the common electrode, the electric field having a component parallel with the substrate, wherein a storage capacitor is formed between the second portion of the conductive layer and an overlapping portion of the black matrix with the second interlayer insulating film interposed therebetween.
