摘要： A liquid crystal display element does not include an orientation layer for orienting a liquid crystal material injected between a pair of substrates thereof. Liquid crystal molecules in the liquid crystal material are oriented randomly in random directions between the substrates. Macroscopically, the liquid crystal molecules of the liquid crystal material are oriented omnidirectionally in a substrate in-plane direction, so that the molecules have an equal random probability of orientation in each direction. Microscopically, however, the liquid crystal molecules of the liquid crystal material are unidirectionally oriented. Among the types of possible orientations are: a type wherein micro-domains in the liquid crystal material are respectively oriented in one direction and occupy an entire micro-area of a substrate in-plane direction; another type of orientation includes a type wherein a plurality of micro-domains are dispersively distributed; and still another type of domain is a type wherein random changes in orientation occur in the micro-domains; and a still further type of orientation of the liquid crystal molecules has random changes in orientation in a broad area. Since the orientations are generally omnidirectional in a substrate in-plane direction; it is possible to form a liquid crystal display element in combination with a pair of polarizers. Optical anisotropy in the in-plane direction and adverse effects of rubbing are prevented.

摘要： A method of manufacturing a liquid crystal display device including the steps of: preparing a parent substrate having an orientation structure on the surface thereof subjected to orientation treatment; interposing primary liquid crystal material between a child substrate not subjected to orientation treatment and the parent substrate, and transferring an orientation state corresponding to the orientation structure of the parent substrate to the child substrate; separating the parent substrate and the child substrate while heating the primary liquid crystal material in an isotropic phase; and forming the liquid crystal display device by using the child substrate. At least one of the two substrates of the liquid crystal display device is not required to be subjected to direct rubbing treatment. It is therefore possible to prevent device defects and performance degradation to be caused by electrostatic charges generated by rubbing.

摘要： No rubbing treatment is done on a pair of transparent substrates. A liquid crystal layer is sandwiched between these transparent substrates to exhibit a multi-domain structure wherein liquid crystal molecules are oriented to various directions at the interface between the liquid crystal layer and a transparent substrate so that the liquid crystal molecules can be considered to be orientated at every direction at an equal possibility with respect to the directions in a plane parallel to the transparent substrate. The transparent substrates constitute a liquid crystal display cell having a reference direction such as an observation direction. A pair of polarizers are disposed outside the transparent substrates to have a transmission or an absorption axis aligned with the observation direction.
