A new kind of liquid crystal display (LCD) which positive dichroic dye disperses in LC is described in this paper. The quasi guest-host effect LCD is composed of a polarizer, twisted-nematic effect liquid crystal layer, and a guest- host effect liquid crystal layer which positive dichroic dye disperses in positive dielectric anisotropy nematic LC. Its multiplexing ability is as high as that of the twisted- nematic effect, and its contrast is as high as that of the guest-host effect of negative contrast display. The technological conditions of the new kind of LCD are similar to those of twisted-nematic LCD. The unfavorable factors are that it needs two liquid crystal layers and that the weight increases to some degree.
