Abstract
A light-emitting device includes a first electrode reflecting in a spectral range, a second electrode, and a light-emitting layer extending between the first and second electrodes and configured to emit electromagnetic radiation in the spectral range, the electromagnetic radiation emitted by the light-emitting layer being circularly polarized in a first polarization direction, the electromagnetic radiation reflected by the first electrode being circularly polarized in a second polarization direction, opposite to the first polarization direction. The second electrode is structured so as to define opaque patterns in the spectral range, arranged to block transmission of the circularly polarized electromagnetic radiation in the first polarization direction, and a spacing zone spacing apart the opaque patterns from one another and transparent in the spectral range so as to allow transmission of the circularly polarized electromagnetic radiation in the second polarization direction.
