The authors fabricated OLED devices with enhanced out‐coupling efficiency, made using corrugated substrates which have nanostructures imprinted from a self‐assembled block‐copolymer pattern. We optimized the substrate for transparent OLED lighting by shortening the pattern pitch to develop a new substrate that is transparent with 0.1 % haze and an out‐coupling efficiency 1.79 times that of a device made with a flat glass substrate.
