ABSTRACT:
A light scattering liquid crystal device having a double structure composed of (1) a first display panel of light scattering type which comprises a pair of transparent substrates each having a transparent electrode layer and a light controlling layer formed therebetween, said light controlling layer containing a liquid crystal material and a transparent solid substance and (2) a second display panel comprising a pair of transparent substrates each having an electrode layer and a liquid crystal material filled therebetween, selected from a guest-host type liquid crystal display panel containing a dichroic dye and a twisted or super-twisted nematic liquid crystal display panel having a pair of polarizers. The device achieves brightness and high contrast.
