  • Publication number: 20140014936
    Abstract: In an organic thin film (a light emitting layer) of an organic EL element, an organic thin film having an emitting material which is made up of an organic polymer main backbone polymerized with a molecular chain, which emits light having a maximum value at a wavelength different from a wavelength at which an emission spectrum emitted by the main backbone itself has a maximum value, and nanosized particles which are mixed into the emitting material is used as the light emitting layer. According to the above configuration, the maximum values of the emission spectra of light emitted by the molecular chain and the main backbone of the emitting material can be increased. Moreover, the light which has the emission spectra having the plural maximum values can be generated without depending on the plural emitting materials, so that the light emitting layer can be manufactured easily.

  • Publication number: 20140008635
    Abstract: An organic electroluminescence element includes: an organic layer which is located between a first electrode layer and a second electrode layer; a light extraction layer which is located on at least one surface of the first electrode layer and the second electrode layer so that directivity of light is changed; and a substrate located on the light extraction layer. The light extraction layer has a base material and a light-scattering particle of 1 to 5 wt. % of the base material. The above configuration allows a light extraction layer to be a single layer and makes it difficult to form a gap at an interface between a base material and light-scattering particles, so that light extraction efficiency can be enhanced.

  • Publication number: 20130320324
    Abstract: An organic EL device includes: a first substrate having electrical conductivity; an organic layer formed on the first substrate; a second substrate having translucency; and an electrode layer formed on the second substrate. The electrode layer on the first substrate and the organic layer on the second substrate contact each other. The organic layer is not formed in the peripheral portion of the second substrate. In the region where the organic layer is not formed, a portion of the electrode layer is provided to extend, and the first substrate is not present to face the extended electrode layer, and the portion of the electrode layer is exposed to form an electrode portion. Thus, the electrode portion can be formed by a simple procedure in which, for example, the first substrate is removed, and the organic EL device can be efficiently manufactured.
