A display sheet is disclosed comprising, a substrate, first transparent conductors, second conductors and, between first and second conductors, at least one imaging layer comprising a substantial monolayer of isolated domains of liquid-crystal material, dispersed in a continuous matrix, wherein said domains of liquid-crystal material comprises a mixture of at least two populations, a first population comprising a first liquid-crystal material having a first .lamda..sub.max within the infrared spectral region and a second population comprising a second liquid-crystal material having a second .lamda..sub.max within the visible spectral region. Alternately, the imaging layer can comprise a substantial monolayer of isolated domains of liquid-crystal material comprising a population of domains comprising a liquid-crystal material having a .lamda..sub.max between 700 and 800 and having a half-peak width that extends into both the visible spectrum region and the infrared spectral region.
