Abstract: A method of fabricating a light emitting device comprises providing a mold having an unpolished surface with an arithmetic mean roughness Ra in a range from 0.1 ?m to 10 ?m, depositing a thin polymer film over the surface of the mold, wherein the film has a thickness in a range from 1 ?m to 100 ?m, positioning a light emitting body onto the thin polymer film, wherein the light emitting body includes an anode, a cathode, and a light emitting layer positioned between the anode and the cathode, and separating the thin polymer film with the light emitting body from the mold. A light emitting device is also described.
