ABSTRACT:
First display electrodes are formed on a first electrode substrate. Second display electrodes are formed on a second electrode substrate in such a direction as to intersect at right angles with the first display electrodes. In order to obtain a liquid crystal display device provided with a screen having a large contrast ratio, masking films for intermittently masking regions between the display electrodes, formed on at least one of the first electrode substrate, and the second electrode substrate are formed on the display electrodes on the other electrode substrate.
