Extremely high light out‐coupling efficiency from a transparent organic light‐emitting diode integrated with microstructures on both sides of the device is reported. The metal free device offers dramatically reduced surface plasmonic and intrinsic absorption losses. Moreover, high refractive index micropatterns with optimal light extraction condition are fabricated based on the well‐matched analysis of optical simulations.
