1. A light emitting device comprising:
a transparent organic light emitting device; and
a single optically active light-blocking element comprising:
a linear polarizer; and
a quarter-wave plate,
wherein the transparent organic light emitting device comprises a chiral complex emitter that produces circularly polarized light, the quarter-wave plate converts the circularly polarized light into linearly polarized light, and the linear polarizer filters the linearly polarized light, and
wherein the chiral complex emitter, the quarter-wave plate, and the linear polarizer are configured to allow transmission of light, generated by the transparent organic light emitting device and within the transparent organic light emitting device, through a single side of the light emitting device.
