摘要： A liquid crystal display device comprises: a layer of a chiral liquid crystal material disposed between first and second substrates; and means for applying a voltage across the liquid crystal layer. A first region of the liquid crystal layer is an active region for display and a second region of the liquid crystal layer is a nucleation region 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.

摘要： A liquid crystal display device includes two substrates, a liquid crystal layer sandwiched between the substrates and two alignment films, each being provided on one surface of associated one of the substrates so as to face the liquid crystal layer. The device defines multiple picture elements. At least one of the two alignment films is made of a polymer material that includes a main chain, an atomic group having a bond that is selectively cut when exposed to an actinic ray and a side chain bonded to the main chain via the atomic group. The polymer material with the side chain can give a pretilt angle of greater than 85 degrees but 90 degrees or less to liquid crystal molecules. The polymer material without the side chain can give a pretilt angle of 2 degrees to 15 degrees to the liquid crystal molecules.

摘要： In a liquid crystal display apparatus 100 that includes a pair of substrates and a vertical alignment liquid crystal layer 14, one substrate 1 has a plurality of protrusions 24 substantially in a columnar shape on a surface in contact with the liquid crystal layer 14. The contour of the upper surface of each protrusion 24 on a surface parallel to the substrate 1 includes a linear portion extending in a substabtially straight line along a direction X. The shape of the contour of the upper surface of the protrusion 24 has line symmetry with respect to an axis along a direction Y, does not have line symmetry with respect to an axis along the direction X, and does not have a rotational symmetry axis in the direction normal to the substrate. The ratio WY/L of the length WY of the upper surface of each protrusion 24 in the direction Y to the length L of the linear portion is at least 1.6 but no more than 2.5. Viewed from the direction normal to the substrate, the area ratio of the regions where the plurality of protrusions 24 have been formed to the overall surface in contact with the liquid crystal layer 14 is no more than 30%. The liquid crystal molecules located in the middle of the liquid crystal layer 14 in the thickness-wise direction are pretilted towards the direction Y from the direction normal to the substrate when no voltage is applied.
