A semiconductor device comprises a plurality of coloured deformable mirrors controllable by electrical circuitry. Groups of mirrors, responsive to the electronic signals, are selectably operable to reflect incident light. The deformable mirrors are coated with an optical thin film interference colour coating having at least a layer that is substantially transparent to the visible light. As well the optical thin filminterference colour coating includes at least one further layer that is partially absorbing with respect to the visible light. The spectral reflectance and absorptance of the deformable mirror is modified in order to obtain a desired reflectance colour by the process of optical interference enhanced absorption in the optical thin film interference colour coating. The optical thin film interference colour coating has predetermined layer thicknesses and materials; the substantially transparent layer substantially determines the desired reflected colour.
