摘要： A method is provided that allows simultaneous control of macroscopic azimuthal and zenithal liquid crystal alignment (φ, θ) across a liquid crystal layer by controlling the area ratios between first, second and third different types of alignment region (T1, T2, T3) in a patterned alignment layer, the three different types of alignment region (T1, T2, T3) tending to induce liquid crystal alignment in the liquid crystal layer in three different respective, non-coplanar, principal orientations (z, x, y). In the illustrated example, the first type of alignment region (T1) tends to induce substantially homeotropic alignment (in the z direction) and the second and third types of alignment region (T2, T3) tend to induce substantially planar alignment in different, orthogonal, principal orientations (in the x and y directions). Control of macroscopic zenithal liquid crystal alignment (θ) is achieved by controlling the area ratios between the homeotropic (T1) and planar region types (T2, T3), and control of macroscopic azimuthal liquid crystal alignment (φ) is achieved by controlling the area ratio between the two planar region types (T2, T3).
