DISPLAY DEVICES

摘要

A display device is described which comprises a liquid crystal host material and an anisotropically emitting fluorescent guest material dissolved in the host material such that the molecules of the guest material align with the molecules of the host material. An electric field applied across the host material causes the direction of radiation emitted by the guest material incident on an interface between two materials of different refractive index to vary so as to control the amount of radiation emitted by the display.
