Liquid Crystal Display Device |
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. |
