ABSTRACT:
Light emitting devices comprising a transparent substrate, a reflective layer on the substrate having at least one opening therein, a waveguiding layer on said reflective layer, and at least one OLED on the waveguiding layer for emitting light of a predetermined color. The light emitted from each OLED is directed through the at least one opening in the reflective layer for emission through the substrate.
