Abstract
The present invention provides a Top-Emitting Organic Light Emitting Diode (TEOLED) and a manufacturing method thereof. The TEOLED includes a substrate; a stack structure on the substrate; a cathode layer covering the stack structure; and a light-scattering layer composed of nano particles and including a concave and convex structure. The present invention can effectively improve cathode transmittance of the TEOLED and modulate the coupling output of lights with multiple wavelengths.
