ABSTRACT:
An active matrix type liquid crystal display device in the lateral electric field system is disclosed, in which a high aperture factor is ensured even in a narrow pitch case, while also ensuring high contract and reduced vertical stroke is disclosed. In a liquid crystal display device, in which substantially bank-like third insulating film208is formed a video signal line204and covered by a common electrode210, a light shield electrode213is formed underneath an extension of a common electrode210from an edge of a video signal line204. With this arrangement, a liquid crystal display device is realized, which shields light from the sides of a step part as well as ensuring high aperture factor and high contrast.
