ABSTRACT:
A liquid crystal device is constituted by disposing a liquid crystal between a pair of substrates each provided with an electrode to provide an effective optical modulation region and a peripheral region. At least one substrate of the pair of substrates comprises an intermediate layer disposed between the substrate and the electrode in the effective optical modulation region and the peripheral region, and the electrode on the intermediate layer comprises a first electrode disposed at least in the effective optical modulation region and a second electrode disposed in the peripheral region. The first and second electrodes are separated from each other. The intermediate layer may preferably include a color filter, a light-interrupting layer and a coating layer.
