Abstract A liquid crystal device is constituted by a pair of oppositely spaced substrate each having on its opposite surface a group of stripe electrodes disposed to intersect with those disposed on the other substrate, and a liquid crystal disposed between the substrates so as to be driven by a voltage applied through the stripe electrodes. The group of stripe electrodes on at least one of the pair of substrates are formed through a lithographic step including dividing the stripe electrodes into at least two divisions at a line parallel (or perpendicular) to the extension of the stripe electrodes, and repeating a pattern exposure for each division of the stripe electrodes so as to dispose a joint between the divisions of the stripe electrodes at a non-display part including a spacing between two stripe electrode on the same substrate (or at a part in alignment with a non-display part including a spacing between two stripe electrodes on the opposite substrate). In an embodiment, the liquid crystal device is provided with a dummy electrode pattern for promoting the liquid crystal injection.
A method for producing a liquid crystal device comprising: providing a cell structure comprising a pair of substrates disposed opposite to each other with a gap therebetween, said cell structure having image display pattern electrodes in a region, a portion of said cell structure other than said region having at least one substrate bearing a dummy pattern film with a width narrower than that of the image display pattern electrodes, the cell structure further comprising a sealing member disposed at a peripheral part of the substrates to seal the gap between the substrates while providing an injection port; and injecting a liquid crystal into said cell structure through the injection port.
