Abstract
A coexistence with normal and reverse scattering modes is demonstrated in a single liquid crystal (LC) cell by using a polymer stabilized effect. The homogeneously oriented or twisted LC cell containing a small amount of reactive mesogen is exposed with UV light under a suitable curing voltage application. A light scattering state is obtained and it becomes clear by applying voltage. The cell fabricated without the curing voltage shows a reverse mode property, that is, a transparent voltage off-state and the light scattering on-state. A driving voltage of the normal mode is almost the same as that of the reverse mode. A domain with the normal mode property is successfully fabricated in the reverse mode LC cell by two step UV exposures through a photomask with and without the curing voltage. Scattering and transparent patterns simultaneously turns to transparent and scattering states without electrode partitions.
