ABSTRACT:
A liquid crystal device is formed by disposing a liquid crystal between a plurality of elongated first display electrodes on a first substrate and a plurality of elongated second display electrodes on a second substrate so as to form a pixel at each intersection of the first and second display electrodes. The spacings between the pixels are masked by a metal oxide light-shielding mask disposed in lamination with the first display electrodes with an intermediate insulating film. The metal oxide light-shielding mask is separated into a plurality of discrete metal oxide masking films each allotted to a pixel at parts in alignment with at least one of first and second metal lead electrodes disposed along and in electrical contact with the first and second display electrodes. The structure is effective for preventing leakage light through a spacing between pixels without causing a short circuit between pixels, liquid crystal alignment disorder or peeling-off of the insulating film.
