摘要： A liquid crystal device comprises a cell (1) formed by a layer (2) of nematic or long pitch cholesteric liquid crystal material contained between two cell walls (3, 4). One wall (4) carries a surface treatment giving a first azimuthal alignment direction with or without a surface pretilt to liquid crystal molecules. The other wall (3) carries a surface treatment capable of separately providing both a preferred, substantially homeotropic alignment of the adjacent liquid crystal, and a defined azimuthal second alignment direction to the adjacent liquid crystal dependant upon liquid crystal molecular arrangement. The first and second alignment directions are approximately orthogonal. Polarisers (13, 14) may be arranged on either side of the cells walls with their polarization axes parallel or perpendicular to the two azimuthal directions. In addition one or more birefringent compensator layers (19, 20) are disposed on one side or on both sides of the cell (1). The compensator layers (19, 20) may be formed of aligned polymer layers, or aligned liquid crystal material, either in a liquid form in a cell, or dispersed in a polymer sheet, or sheets of quartz or calcite slices. The device operates between two different voltage levels, one level (V1) providing a non twisted liquid crystal molecular arrangement, the other and higher voltage (V2) providing a twisted molecular arrangement.

摘要： Liquid crystal devices are described that exhibit bistable, tri-stable or other multistable operation. The stable liquid crystal configurations are attained using a surface alignment grating (144) on the internal surface of at least one cell wall (142). The surface profile of the surface alignment grating comprises three or more defect sites per grating period and permit the liquid crystal molecules to adopt any one of two or more stable pretilt angles in the same azimuthal plane. Application of a suitable voltage causes the liquid crystal material to switch between the stable configurations.

摘要： A photopolymer mixture is capable of use for a liquid crystal alignment layer. An alignment layer is formed from such a photopolymer mixture. The mixture comprises at least two polymerisable materials which are blended together in proportion so as to give a predetermined, preferably low, surface energy. A low surface energy, e.g., less than 4×10−2 N/m, can result in an alignment layer which imparts a particular orientation to liquid crystal molecules with out requiring any post-cure treatments. The polymerisable materials may be monomers, oligomers, or diluents that form long chain molecules when cured, and the mixture may contain additives to lower the overall surface energy.

摘要： A method and apparatus for forming a patterned layer having a surface profile that provides relief structures within an electronic device. The method comprises the steps of taking a carrier film (50) having an inverse of the required surface profile formed on one side thereof, taking a layer of fixable material (54) located on a substrate (52), laminating the carrier film (50) and substrate (52) such the carrier film causes the required surface profile to be formed in the layer of fixable material with a predetermined offset, and then fixing the fixable material. Lamination may be performed using rollers (56,58) or a vacuum process. The process is designed to ensure that the offset can be kept as low as possible, preferably to within 150 nm.
