Abstract
A liquid crystal display device has a plurality of gate bus wirings and source bus wirings on one of paired substrates. Moreover, a inter-layer insulating film made of an organic material is provided on thin film transistors of respective picture elements, and a picture element electrode is provided on the inter-layer insulating film. Furthermore, the liquid crystal display device is provided with an additional capacity common wiring which is provided on the inter-layer insulating film and forms an additional capacity section between the picture element electrode and the additional capacity common wiring. As a result, the liquid crystal display device can realize high quality and a high aperture ratio.
