Abstract
An organic light emitting device is described. In certain embodiments, the device has a transparent substrate, a transparent grid layer disposed over the substrate, and an OLED disposed over the grid layer. The OLED can include an anode, a cathode, and at least one organic layer between the anode and cathode. A refractive index of the transparent grid layer is less than or equal to a refractive index of the transparent substrate. In certain embodiments, the at least one organic layer includes an electron transport layer having a thickness of at least 50 nm. In certain embodiments, the refractive index of the transparent grid layer is less than n=1.20, or in certain embodiments, less than n=1.05. Methods of manufacturing an organic light emitting device are also described.
