Abstract

See full text

The invention is based on the idea of providing a light emitting diode (OLED) device which contains a substrate with a photonic crystal, whereby the formed film structure induces enhancement of the liberation of photons trapped inside the light emitting device structure. The photonic crystal structure is a film structure on a substrate produced using a combination of high and low refractive index materials, at least one of the materials being based on a liquid phase deposited metal-oxide or metalloid oxide material. By means of the invention light trapped due to total internal reflection in a waveguide acting light emitting structure can be extracted efficiently from the device by introducing the photonic crystal device structure between the substrate and conductive anode layer.
