LAYERED STRUCTURE FOR OLED DEVICE, METHOD FOR MANUFACTURING THE SAME, AND OLED DEVICE HAVING THE SAME

Document Type and Number:

WIPO Patent Application WO/2013/187735

Kind Code:

A1

Abstract:

A layered structure for an organic light-emitting diode (OLED) device, the layered structure including a light-transmissive substrate and an internal extraction layer formed on one side of the light-transmissive substrate, in which the internal extraction layer includes (1) a scattering area containing scattering elements composed of solid particles and pores, the solid particles having a density that decreases as it goes away from the interface with the light-transmissive substrate, and the pores having a density that increases as it goes away from the interface with the light-transmissive substrate, and (2) a free area where no scattering elements are present, formed from the surface of the internal extraction layer, which is opposite to the interface, to a predetermined depth.
