Abstract

A light emissive or photovoltaic device comprising: a cathode structure for injecting electrons, the cathode structure having one or more constituent regions; an anode structure for injecting holes, the anode structure having one or more constituent regions; and an organic light emissive component located between the anode structure and the cathode structure; the refractive indices and the thicknesses of the or each constituent region of the cathode and anode structures and of the light emissive component being such that the emission or absorption spectrum of the device is substantially angularly dependent.
