Claims
- 1. A method of fabricating one of a plurality of multi-digit liquid crystal display cells from at least two transparent sheets each of said at least two transparent sheets being approximately rectangular in shape, each of said sheets having a pair of substantially longitudinal ends and a pair of substantially transverse ends, each of said liquid crystal display cells having a liquid crystal composition interposed therein, comprising the steps of:
- providing an alignment means for forming a plurality of grooves on a surface of said sheets;
- forming a plurality of grooves on a first surface of each of said at least two transparent sheets, said formation of said grooves being performed by utilizing said alignment means, said formation of said grooves commencing along at least one of said ends of said first surface of each of said transparent sheets, said formation of said grooves continuing in substantially said one direction along said first surface of each of said transparent sheets until at least one opposite end is reached;
- placing said first surface of one of said at least two transparent sheets in contact with said first surface of another of said at least two transparent sheets such that said longitudinal and transverse ends of said one transparent sheet are in alignment with said longitudinal and transverse ends of said another transparent sheet, the direction of said grooves on said first surface of said one transparent sheet being approximately orthogonal to the direction of said grooves on said first surface of said another transparent sheet thereby yielding a liquid crystal structure;
- injecting a layer of said liquid crystal composition between said transparent sheets; and
- dividing said liquid crystal structure into a plurality of liquid crystal display cells, said structure being divided by providing a plurality if cuts along the longitudinal axis of said structure, each of said cuts extending along the transverse axis of said structure and extending in a direction approximately parallel to each of said transverse ends, whereby said grooves on said first surface of each of said transparent sheets are unidirectional with respect to other grooves on the same sheet.
- 2. A method of fabricating a plurality of multi-digit liquid crystal display cells in accordance with claim 1 wherein a plurality of holes are formed along one of said longitudinal ends of one of said at least two transparent sheets, said holes being approximately equally spaced along said longitudinal axis of said liquid crystal structure and adjacent to a first longitudinal end of said structure when said first surface of said one transparent sheet is placed in contact and alignment with said first surface of said another transparent sheet.
- 3. A method of fabricating a plurality of multi-digit liquid crystal display cells in accordance with claim 2 wherein said liquid crystal composition is injected between said transparent sheets by dipping said first longitudinal end of said liquid crystal structure into a liquid crystal composition reservoir, said approximately equally spaced plurality of holes being immersed therein.
- 4. A method of fabricating a plurality of multi-digit liquid crystal display cells in accordance with claim 3 wherein said formation of said grooves is accomplished by rubbing said first surface of each of said transparent sheets, said first surface being rubbed in one direction, said one direction extending from said at least one end of said first surface of each of said transparent sheets and terminating at said at least one opposite end thereof.
