Abstract

It is disclosed an appearance-modifying device (), for modifying the visual appearance of a surface covered thereby. The appearance-modifying device () comprises two oppositely arranged substrates (), which are spaced apart by a spacer structure (). The spacer structure () spaces apart the two substrates () in such a way that a space between the two substrates () is divided into a plurality of cells (), the shapes of the individual cells () being such that an aperiodic cell pattern () is formed by the cells (). Each cell () may comprise an optically transparent fluid having a plurality of particles dispersed therein. The particles are moveable in the fluid through application of an electric field. An appliance at least partly covered by the appearance-modifying device () is also disclosed. Furthermore, it is disclosed a method for manufacturing the appearance-modifying device.
