摘要： Monomers with photopolymerization characteristics and an initiator for polymerization are added to a liquid crystal composition having a ferroelectric liquid crystal phase (S5). In a state (S6) where coexist two domains which differ from each other in directions of molecular major axes in the ferroelectric liquid crystal phase, light is projected to the liquid crystal layer to form a polymer reticulate structure therein (S7). As a result, this state is made a stable one and the liquid crystal shows macroscopic switching behaviors among two states causing dark and bright displays respectively, and the above-described state causing halftone display.

摘要： A polymer having spontaneous polarization with the same codes as liquid crystal is introduced into a liquid crystal layer of the smectic liquid crystal cell so that the responding speed is improved (second liquid crystal cell). In another way, a polymer having spontaneous polarization with opposite codes to the liquid crystal is introduced into liquid crystal showing .tau.-V.sub.min characteristic so that a driving voltage is lowered (first liquid crystal cell). These polymers are previously added to a liquid crystal composite before injecting into the liquid crystal cell. In another way, after a photochemically polymeric monomer is added to the liquid crystal composite and the obtained product is injected into the liquid crystal cell, the monomer is polymerized by the projection of a light. Furthermore, the liquid crystal cell into which the polymer is introduced is heated again so as to show I phase and is cooled so that the tone display is realized.

摘要： A mixture of a ferroelectric or anti-ferroelectric liquid crystal material and a monomer having a single photopolymeric functional group is injected in the space between two electrode substrates while heat is applied. After cooling of the mixture it is irradiated with ultraviolet light at a temperature at which the liquid crystal material remains in the smectic phase so as to polymerise the monomer. Areas of liquid crystal material requiring different threshold voltages for switching are thereby produced. Alternatively such areas can be produced by changing the conditions applied to a mixture of liquid crystal material with a suitable dopant so as to cause separation of the dopant out of the liquid crystal material in order to provide a polarity of nucleation points for controlling domain formation within the liquid crystal material. Such control of domain formation can be used to provide greyscale in a liquid crystal device.

摘要： A manufacturing method of a liquid crystal display element is provided with the steps of: arranging a pair of insulating substrates face to face with each other and bonding them to each other, each of the insulating substrates having electrodes formed thereon with an alignment film formed in a manner so as to cover the electrodes; and filling the gap between the two substrates with a mixture that is made by mixing a ferroelectric liquid crystal (FLC) composition with isotropic micro structural elements that locally give different threshold-value characteristics to liquid crystal molecules in the liquid crystal composition. With this arrangement, it is possible to provide a liquid crystal layer in which the isotropic micro structural elements are formed into a striped organization with the isotropic micro structural elements being sandwiched between smectic layers of the FLC composition. Consequently, it becomes possible to easily provide a liquid crystal display element with high quality that achieves a gray scale display suitable for practical use.

摘要： A liquid crystal display element is manufactured as follows: First, a mixture containing a ferroelectric liquid crystal (FLC) composition and a monofunctional monomer is injected into the space between opposing two electrode substrates, each of which is constituted by a substrate, an electrode, an alignment film and a polarization plate; next, the mixture is heated by irradiating it with ultraviolet light to a temperature at which the FLC composition exhibits a nematic phase or an isotropic phase so that the monomer is polymerized, and then it is cooled off. With this arrangement, isotropic micro structural elements, which locally give different threshold-value characteristics in the above-mentioned mixture, are formed into a striped structure so that a liquid crystal layer is formed. This striped structure is formed when the polymer that has been formed as a result of the polymerization is allowed to be sandwiched between smectic layers in the FLC composition during the cooling process. Consequently, it becomes possible to make the size of domains smaller as compared with the size of a pixel, and to uniformly distribute the domains over a wide range; thus, gray scale display of a liquid crystal display element is achieved.

摘要： A driving method for an image display apparatus is disclosed. The image display apparatus includes an image display panel including a plurality of pixels each including first, second, third and fourth subpixels and arrayed in a two-dimensional matrix. A signal processing section determines an expansion coefficient based on a saturation value and a maximum value of brightness in an HSV color space expanded by addition of a fourth color to three primary colors. First to third correction signal values and a fourth correction signal value are determined based on the expansion coefficient, first to third subpixel input signals and first to third constants. A fourth subpixel output signal is determined from the fourth correction signal value and a fifth correction signal value determined from the expansion coefficient and the first to third subpixel input signals and output to the fourth subpixel.
