ABSTRACT:
A method for fabricating a liquid crystal display device includes the steps of providing a pair of insulated electrode-carrying plates, depositing on the surface of one of the plates, overlying the electrodes a layer of photopolymeric material approximately 0.0005 inches in thickness, masking and light exposing the photopolymeric layer and thereafter developing a way with a suitable solvent a predetermined area of material to provide a cavity in the photopolymeric layer through which the electrodes on the plate are accessible. On the surface of the second one of the plates whereat the second set of electrodes are located, a layer of photopolymeric material of approximately 0.0005 inches in thickness is deposited by masking and light exposing the second photopolymeric material and thereafter developing away with a suitable solvent, a predetermined area of material which is slightly smaller than the area provided by the first area of material is produced to provide a cavity in the photopolymeric layer through which the electrodes on the second plate are accessible. The first and second electrode-carrying plates are bonded together to seal the edges of the cavity. The cavity is filled with a liquid crystal composition through an aperture provided in the photopolymeric layer on one of the plates and thereafter the hole is sealed to retain the liquid crystal composition in the cavity.
