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 μm to 10 μm, depositing a thin polymer film over the surface of the mold, wherein the film has a thickness in a range from 1 μm to 100 μm, 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.

1-32. (canceled)
A light emitting device comprising:
- a thin polymer substrate having a thickness in a range from 1 μm to 100 μm, and having an external surface and an opposite internal surface, wherein the external surface and the internal surface each has an arithmetic mean roughness Ra in a range from 0.1 μm to 10 μm;
- and
- a light emitting body disposed over the internal surface of the thin polymer substrate, the light emitting body comprising an anode, a cathode and at least one light emitting layer positioned between the anode and the cathode, wherein at least one of the anode, the cathode, and the at least one light emitting layer has an arithmetic mean roughness Ra in a range from 0.1 μm to 10 μm.
