  • ORGANIC EL ELEMENT AND METHOD FOR MANUFACTURING THE ORGANIC EL ELEMENT AND ORGANIC EL ELEMENT EVALUATING METHOD
    Publication number: 20100314995
    Abstract: Provided are an organic EL device having improved conductivity of an anode compared with conventional organic EL devices, and a method for manufacturing such organic EL device. The organic EL device is provided with a layer-like optical element (40), which at least contains a liquid crystal material and a dye, has a refractive index distribution based on orientation of liquid crystal molecules constituting the liquid crystal material, and has the refractive index distribution fixed; a substrate (11) which can transmit visible light; a light emitting layer (60) composed of an organic EL material; a cathode (70); and an anode (50). Each of the cathode (70) and the anode (60) is formed layer-like. The organic EL device is further provided with an alignment film (12), and the alignment film (12) and the optical element (40) are in contact with each other.
