ABSTRACT:
A liquid crystal device with little crosstalk and improved contrast is obtained by using an electrode plate including a substrate, a plurality of transparent conductor stripes disposed on the substrate, a plurality of elongated metal films each disposed at least one side of and electrically connected with one of the conductor stripes so as to form a transparent region and an opaque region of a conductor stripe, and a second metal film for light-shielding disposed on the substrate so as to be electrically insulated from the conductor stripes with an insulating film. The second metal film is separated into a plurality of discrete masking parts each in the form of a frame leaving an aperture; and the plurality of discrete masking parts are disposed so that plural masking parts among them are disposed along one conductor stripe so as to form plural apertures along the transparent region of the conductor stripe, and the masking parts disposed along one conductor stripe are separated from masking parts disposed along an adjacent conductor stripe at a separating position, which is covered by the first metal film.
