Abstract

A transparent directional polarized light-emitting device includes a transparent anode and a transparent cathode, a radiation-emitting layer between the anode and the cathode, an optically active reflective layer with a reflection band that matches a chirality and at least partially encompasses a wavelength band of radiation emitted from the radiation-emitting layer, the optically active light blocking layer located on a side of the radiation-emitting layer, and a transparent substrate adjacent to the optically active reflective layer.
