    摘要： A liquid crystal display device comprises a first substrate, a first alignment layer (3') disposed on a surface of the first substrate, a second substrate, second alignment layer (3) disposed on a surface of the second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The alignment direction of the first alignment layer (3') has a non-zero component in a first azimuthal direction (7') in a first region (20') of the alignment layer and has a non-zero component in a second azimuthal direction (41') different from the first azimuthal direction (7') in a second region (21') of the first alignment layer. In consequence, in zero applied electric field across the liquid crystal layer, a first liquid crystal state is stable in a first volume (22) of the liquid crystal layer defined by the first region (20') of the first alignment layer (3') and a second liquid crystal state topologically equivalent to a desired operating state of the device is stable in a second volume (23) of the liquid crystal layer defined by the second region (21') of the first alignment layer (3'). The second volume (23) of the liquid crystal layer acts as a nucleation region and promotes formation of the desired operating state in the first volume (22) of the active layer when an electric field is applied across the liquid crystal layer. The first volume (22) of the liquid crystal layer acts as an active region for displaying an image.

    摘要： A liquid crystal display device comprises: a layer of a chiral liquid crystal material disposed between first and second substrates (1,1'); and means for applying a voltage (6,6',7) across the liquid crystal layer. A first region of the liquid crystal layer is an active region (10) for display and a second region of the liquid crystal layer is a nucleation region (11) for generating a desired liquid crystal state in the first region when a voltage is applied across the liquid crystal layer. The ratio of the thickness d of the liquid crystal layer to the pitch p of the liquid crystal material has a first value (d/p) A in the first region of the liquid crystal layer and has a second value (d/p) N different from the first value in the second region of the liquid crystal layer. The value (d/p) N of the ratio of the thickness d of the liquid crystal layer to the pitch p of the liquid crystal material in the second region of the liquid crystal layer is selected such that, when no voltage is applied across the liquid crystal layer, the liquid crystal state stable in the second region of the liquid crystal layer is topologically equivalent to the desired liquid crystal state under application of a voltage.

    摘要： An OCB device comprises upper and lower substrates (1, 1'), each provided with an alignment layer (2,2'). A liquid crystal layer (3) is provided between the substrates.
    The lower substrate (1') has a low pre-tilt in regions A and C, so that an H-state is stable in these regions when no voltage is applied across the liquid crystal layer. Region B has a high pre-tilt on the lower substrate 1', so that a HAN state is stable in region B under zero applied voltage.
    When a voltage is applied across the liquid crystal layer (3) a V-state is formed at the interface between the HAN-state and the H-states. This V-state then displaces the H-states in regions A and C.
    The high pre-tilt region, region B, is acting as a nucleation region. The V-state forms at a lower applied voltage than if the nucleation region is not provided.

    摘要： A patterned retarder is made by forming an alignment layer 2 on a substrate 1. The alignment layer 2 is rubbed in a first rubbing direction to provide a uniformly rubbed alignment layer 2a. The alignment layer 2a is then masked with a mask 5 and subjected to a second rubbing in a different direction to provide first regions A with a first alignment direction and second regions B with a different second alignment direction. The mask is removed and a layer of birefringent material 7 is formed on the alignment layer 6. The optic axis of the birefringent material of the layer 7 adopts the alignment of the underlying alignment layer 6 and the birefringent material is fixed to provide a patterned retarder layer 8.

    摘要： A liquid crystal display device comprises a first substrate, a first alignment layer (3') disposed on a surface of the first substrate, a second substrate, second alignment layer (3) disposed on a surface of the second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate.
    The alignment direction of the first alignment layer (3') has a non-zero component in a first azimuthal direction (7') in a first region (20') of the alignment layer and has a non-zero component in a second azimuthal direction (41') different from the first azimuthal direction (7') in a second region (21') of the first alignment layer. In consequence, in zero applied electric field across the liquid crystal layer, a first liquid crystal state is stable in a first volume (22) of the liquid crystal layer defined by the first region (20') of the first alignment layer (3') and a second liquid crystal state topologically equivalent to a desired operating state of the device is stable in a second volume (23) of the liquid crystal layer defined by the second region (21') of the first alignment layer (3'). The second volume (23) of the liquid crystal layer acts as a nucleation region and promotes formation of the desired operating state in the first volume (22) of the active layer when an electric field is applied across the liquid crystal layer. The first volume (22) of the liquid crystal layer acts as an active region for displaying an image.
