Abstract

A light-emissive device comprising a light-emissive material provided between first and second electrodes such that charge carriers can move between the first and second electrodes and the light-emissive material, wherein the device includes a layer of a polymer blend provided between the first and second electrodes, phase separation of the polymers in the polymer blend having been induced in at least a portion of the polymer blend so as to control the propagation of light emitted by the light-emissive material in a predetermined direction.
