摘要： A liquid crystal device is provided that comprises a layer of liquid crystal material (2) disposed between two cell walls (4, 6) in an arrangement such that the liquid crystal material (2) can adopt any one of two or more stable liquid crystal configurations that will persist in the absence of an applied electric field. The liquid crystal device is operable in two modes; a first mode in which application of an appropriate latching voltage pulse can select any one of the two or more stable liquid crystal configurations, and a second mode in which application of an electric field can switch the layer of liquid crystal material from a latched configuration to a switched configuration and in which the layer of liquid crystal material will return to said latched configuration when the applied electric field is removed.

摘要： A liquid crystal device is described that comprises a layer of liquid crystal material contained between a first cell wall and a second cell wall. The layer of liquid crystal material being switchable between at least a first state and a second state, said first state and said second state having sufficiently low splay to enable rapid electrical switching therebetween. The internal surface of said first cell wall is arranged to provide two or more surface alignment configurations of different pretilt to said layer of liquid crystal material. Said states may persist in the absence of an applied electric field. In particular, the invention relates to pi-cell devices that allow for rapid switching from the initial splay state to the bend states, and also to bistable or multistable pi-cell devices.

摘要： This invention relates to a liquid crystal device wherein the surface profile of a surface alignment grating stabilises at least one stable state. The invention involves the introduction or breaks (34, 36, 38) or discontinuities into the grating (10) to divide the grating into a plurality of groove segments. The breaks are discontinuities in the grating in the groove direction, the grating having substantially the same groove direction on each side of the break. The introduction of breaks prevent free movement of defects along the groove of the grating and therefore help to stabilise the desired liquid crystal configuration, either a Defect state or a Continuous state. Suitable breaks involve gaps (34) in the groove ridges (30), necks (36) between the groove ridges (30) and slips or relative displacement (38) of the grating.
摘要翻译：本发明涉及一种液晶显示装置，其中表面对准光栅的表面轮廓稳定至少一个稳定状态。本发明涉及到光栅（10）的引入或断开（34,36,38）或不连续，以将光栅分成多个凹槽段。断裂在光栅中的凹槽方向是不连续的，光栅在断裂的每一侧具有基本上相同的凹槽方向。引入断裂防止缺陷沿光栅槽的自由移动，从而有助于稳定所需的液晶结构，即缺陷状态或连续状态。合适的断裂包括槽脊（30）中的间隙（34），凹槽脊（30）之间的颈部（36）和光滑的相对位移（38）。
