摘要： A surface mode liquid crystal device is made by forming a cell containing a mixture of a liquid crystal and a pre-polymer. An electric field is applied across the cell to arrange the liquid crystal in a predetermined surface mode state, such as the V state in the case of a pi-cell configuration. The liquid crystal is held in this state by the field while the pre-polymer is polymerized or cross-linked, for instance by ultraviolet irradiation. The electric field is then removed. The polymer stabilizes the predetermined surface mode state, for instance preventing relaxation of the V state to twist or splay state in the pi-cell configuration.

摘要： A twisted liquid crystal device includes a liquid crystal layer and first and second alignment layers disposed in opposite sides of the liquid crystal layer. The first and second alignment layers have respective alignment directions which are mutually inclined. A first linear polarizer is disposed on the opposite side of the first alignment layer to the liquid crystal layer. Electrodes apply a variable voltage across the liquid crystal layer which has a twisted liquid crystal structure. The liquid crystal layer is arranged for operation in surface switching mode with first and second regions of the liquid crystal layer adjacent the alignment layers being mutually optically de-coupled so as to define, within the liquid crystal layer when in use, a pair of separate, active optical retarders having mutually inclined optic axes.

The device comprises a layer of liquid crystal material disposed between alignment surfaces. In one mode, a 90° twist is induced in the liquid crystal director. An expression is provided for relating the retardation of the layer to the amount of polarization rotation and the angle between the polarization direction of incident light and the alignment direction at the input side of the liquid crystal layer.

摘要： A display comprises: a single-view image display panel (6); and a parallax optic (8) disposed over a display face of the image display panel for restricting the angular spread of light output from the display face of the image display panel. This enables light to be concentrated in a desired viewing angle range (66), and avoids a user (56) seeing unwanted reflections that may occur as a result of a greater viewing angle range (64) if the parallax optic (8) is not provided. The display may be used, as an example, in a motor vehicle to prevent unwanted reflections from the windscreen (62) of the vehicle.

摘要： A reflective liquid crystal device comprises in sequence a linear polarizer, a retarder arrangement comprising two retarders, and a reflector. A first of the retarders provides a retardation of m&lgr;/2 and a second of the retarders provides a retardation of n&lgr;/4, where m is an integer and n is an odd integer, and wherein at least one of the first and second retarders comprises a Bistable Twisted Nematic (BTN) liquid crystal. This BTN retarder is switchable between a first state in which the retarder provides a retardation of m&lgr;/2 or n&lgr;/4 and a second state in which the retardation is zero.
