Abstract: In a liquid crystal display in which a liquid crystal having spontaneous polarization is sandwiched between substrates, liquid crystal alignment which achieves a wide viewing angle and hardly causes alignment destruction is readily formed. A common electrode is formed by a pair of meshed comb electrodes, and rubbing alignment is performed in the logitudinal direction of teeth of these comb electrodes. When the liquid crystal material transits from a nematic phase or an isotropic phase to a chiral smectic C phase, a positive DC voltage, for example, is applied between a pixel electrode and one of the comb common electrodes, and a negative voltage is applied between a pixel electrode and the other comb common electrode. This readily accomplishes liquid crystal alignment in which smectic layers bend horizontally with respect to the substrate surface in space portions between the interdigitated teeth of the comb electrodes.

Abstract: An electro-optical device may include two pairs of electrodes which apply electric fields oriented at an angle with respect to one another. In this way, a second electric field may be used to create an alignment effect in the electro-optic material which normally is achieved using specially prepared alignment structures. The need for the alignment structures may be reduced or eliminated. The second electric field may be applied, for example, using metallic standoffs which space a top plate from a lower substrate and define a region for the electro-optic material. In this way, in large arrays, the electric field may be applied from a plurality of points improving the uniformity of the applied electric field. In smaller arrays, the field may be applied, for example, using peripheral electrodes.

Abstract: An arrangement (apparatus and method) for selectively modulating incident unpolarized light passing through a birefringent material, such as ferroelectric crystal. The apparatus includes a plate having one or more birefringent layers corresponding to first and second alignment regions. The birefringent layer corresponding to the first alignment region has a first optic axis selectably set in a first orientation and a second orientation. The birefringent layer corresponding to the second alignment region has a second optic axis selectably set in a third orientation and a fourth orientation. A switching means controls the optical axis states of the birefringent material by applying switching voltages to the areas of the birefringent layer. Light having passed through the birefringent layer at locations having the first orientation has a different phase from, and same polarization as, light having passed through locations with the third orientation, independent of a polarization state of the incident light. As a result, the birefringent material has a uniform state at locations where the corresponding optic axes between the first and second alignment regions are parallel, and a diffracting state produced by an interaction between the light having passed through areas having the first orientation and the light having passed through areas having the second orientation. The arrangement is effective for reflective modulators, multilayer modulators or polarization-preserving modulators, and has applications for intensity modulation, blurring modulation and beam steering.

Abstract: The total internal reflection modulator has an electrode array distributed across an area of the reflecting surface of the electro-optic material. The electrode array has multiple sets of electrodes forming an outer rectangle interdigitated with at least one reference set of electrodes forming a inner diamond. A diamond-shaped area with no electrodes is preferably symmetrically within the inner electrodes of the electrode array on the reflecting surface. The uniform voltage difference between the electrodes and the varying lengths of the electrodes creates a fringe electrical field in the electro-optical material and an optical phase grating to diffract the incident light on the reflecting surface. The zero order nondiffracted light becomes the output beam. The optical phase grating will control the incident beam's optical profile at the modulator (near field) and hence the imaged spot size at a focus at the image plane (far field).Alternatively, the total internal reflection modulator can have a diamond-shaped interdigitated electrode pattern within a rectangular shaped area with no electrodes. Using Schlieren optics, the non-zero order diffracted beam becomes the output beam with a modulated optical beam profile.

Abstract: This invention discloses a color liquid crystal display device which can be applied to 7-segment numeric display, for example, A pair of transparent electrodes are disposed on the inner surfaces of a pair of transparent substrates facing each other. One of the transparent electrodes has a function as the display segments and is constituted by two comb tooth-like electrodes that are fixed in a predetermined direction. The direction of teeth of these two comb tooth-like electrodes is in agreement with each other. The other of the transparent electrodes has a flat sheet-like shape. Color filters of two colors are alternately disposed on the two comb tooth-like electrodes in such a manner as to face the other of the transparent electrodes. The direction of disposition of the color filters is in agreement with the direction of the teeth of the comb tooth-like electrodes. The color filters are disposed on the entire surface of the display range including the display segment. A liquid crystal is sealed between the color filters and the other of the transparent electrodes. A voltage is applied across the pair of the transparent electrodes and controls the transmission quantity of the liquid crystal. Thus, segment display can be effected.
