The invention provides an organic light emission diode device which comprises a substrate, and an anode, a light emission functional layer and a cathode which are sequentially laminated on the substrate, a light extraction layer is arranged on a first surface and/or a second surface of the substrate, the material of the light extraction layer comprises nanoparticles with grain size of 50 to 1,500 nanometers and a polymer material, the nanoparticles are ceramic or high-polymer material particles, the polymer material is a heat cured polymer or photo cured polymer material, the thickness of the light extraction layer is 10 to 100 micrometers, the material of the anode is a conductive oxide membrane, the material of the cathode is an elementary substance of gold, silver, aluminum and magnesium or an alloy formed by any combination thereof, and the light emission functional layer at least comprises a hole transmission layer, a light emission layer and an electron transmission layer which are sequentially laminated. The light emergent efficiency of the cathode of the organic light emission diode device is high, so that the luminous efficiency of the device is improved. The invention also provides a fabrication method of the organic light emission diode device. |
