本液晶器件包括:对衬底和一种手性的碟状结构晶体。每块衬底上都有一组显示电极,手性的碟状结构液晶淀积在两块衬底之间的一层膜层上。液晶层被一对相反显示电极夹住的部分的厚度(d)是非常均匀的。在被一块衬底上的一个显示电极和另一块衬底上邻近显示电极之同的一个非电极部分夹住的部分处,液晶的厚度为(D),D—d≥d/2。液晶处在一种符合H>θ_a>H/2的关系的均匀准直的状态中,这里的H表永锥角的一半,θ_a表示手性碟状结构液晶的表观倾角。
The liquid crystal device comprises: a counter substrate and a chiral dish crystal. Each substrate has a set of display electrodes, and a chiral discotic liquid crystal is deposited on a layer of film between the two substrates. The thickness (d) of the portion of the liquid crystal layer sandwiched by the pair of opposite display electrodes is very uniform. At a portion sandwiched by a display electrode on one substrate and a non-electrode portion on the other substrate adjacent to the display electrode, the thickness of the liquid crystal is (D), and D-d? D / 2. The liquid crystal is in a state of uniform alignment that satisfies the relationship of H> θ_a> H / 2, where H is half of the cone of the permanent cone and θ_a is the apparent tilt of the liquid crystal of the chiral dish.
