Patent ID: 7310121

Claim:
A liquid crystal display device comprising: an active matrix substrate comprising: a gate line; a data line intersecting the gate line; a thin-film transistor formed at an intersection of the gate line and the data line; a conductive layer electrically connected to the thin-film transistor, the conductive layer including at least a first portion which functions as a pixel electrode and a second portion which extends in parallel with the gate line; and a common electrode overlapped with the second portion of the conductive layer, the common electrode being a black matrix; an opposed substrate that is opposed to the active matrix substrate; a liquid crystal layer held between the active matrix substrate and the opposed substrate, and driven by an electric field formed between the pixel electrode and the common electrode, the electric field having a component parallel with the active matrix substrate; and a storage capacitor formed between an overlapping portion of the common electrode and the second portion of the conductive layer with an insulating film interposed therebetween.
