Title:
SEALING FILM AND ORGANIC LIGHT EMITTING DIODE USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/014629
Kind Code:
A1
Abstract:
A sealing film (30), which has both a light extraction function and a moisture absorption function that are necessary for organic light emitting diodes and the like, is composed of an organic resin film (31) wherein first particles (32) for light diffusion and second particles (33) for moisture absorption are dispersed. The first particles (32) are formed from a substance that has a higher refractive index than the organic resin film (31) and is capable of transmitting visible light (for example, ZrO2, BaTiO2, TiO2, ZnOx, Y2O3 or Al2O3), and the second particles (33) are formed from a substance that combines with water and is capable of transmitting visible light (for example, an alkaline earth metal oxide, an alkali metal oxide, a metal halide, a metal sulfate or a metal perchlorate).
