摘要： A liquid crystal device that includes a pair of substrates and a composite layer disposed between the substrates. The composite layer has a liquid crystal phase of a liquid crystal material and a resin phase of a resin. The liquid crystal device is made such that the resin phase comprises a resin wall structure which does not contain a substantial amount of the liquid crystal material. To enhance contrast and viewing angle, the resin phase has a rough surface which is sufficient to disarrange an orientation of molecules of the liquid crystal material. The invention is further directed to a method of manufacturing a liquid crystal device, which includes the steps of defining a mixing ratio of two kinds of resin raw materials that have different contact angles, mixing these kinds of resin raw materials, mixing the mixed raw material with a liquid crystal material, and separating the mixed material from the liquid crystal material. In a preferred embodiment the resulting resin phase would have a contact angle with respect to the liquid crystal material in the range of 11.degree. to 15.degree..

The step of forming the regions may include the steps of supplying a composition of the liquid crystal material and the resin material into a space between the paired substrates; and separating the liquid crystal material in a region corresponding to each of the regions from the resin under a condition different from the others. If the resin material is a photo-curing resin material, the separating step may include the steps of masking the composition with a mask having a plurality of regions, each of which has a plurality of openings and is different from the others in condition of the openings; and exposing the composition to light through the mask.

摘要： A liquid crystal display device which has a liquid crystal composition between a first substrate and a flexible second substrate. The liquid crystal composition is filled between the substrates by being dispensed on the first substrate and spread uniformly while the second substrate is being pressed against the first substrate by a roller, and the liquid crystal composition is sealed by sealing resin provided on the sides of the substrates. The gap between the substrates is maintained by spherical spacers and/or a resin structure.
