Abstract

The present invention relates to a display comprising at least one substrate, at least one electronically modulated imaging layer and at least one electrically conductive layer, wherein the electronically modulated imaging layer comprises a self-assembled, close-packed, ordered monolayer of domains of guest-host material, wherein the guest-host material comprises a dichroic or pleochroic dye guest in a light modulating host in a fixed polymer matrix, and wherein the appearance of the display is independent of viewing angle.
