| description | A liquid crystal display which has a small change in contrast ratio and a black level (i.e. background color) when a view point is changed in the upper and lower direction. A nematic liquid crystal material is disposed between two plates (6,4), the plates are oriented (for example rubbed) to cause the liquid crystal material to define a twisted structure in the direction perpendicular to the plates, and the direction of the orientation of the plates is selected so that the normal direction viewing is identical with the direction in which the twisted structure is lost when a voltage is applied across the liquid crystal material. When the direction of viewing is the lower direction, an optical path difference between the plates in the upper area of the liquid crystal display is larger than an optical path difference between the plates in the lower area of the liquid crystal display. When the direction of viewing is the upper direction, an optical path difference between the plates in the upper area of the liquid crystal display is smaller than an optical path difference between the plates in the lower area of the liquid crystal display. |
