Abstract

A light emitting device comprises a light emitting structure in the form of an organic electroluminescent device formed on a transparent substrate (8) through which light from the light emitting structure is emitted. A polarisation-preserving light extraction member with a multiplicity of optical elements (2) over the area of the light emitting structure, is optically coupled to the outside of the transparent substrate to reduce total internal reflection of light within the substrate.
