Abstract:
1. An organic light-emitting device comprising: a pair of first and second electrodes opposed to each other; and a plurality of organic semiconductor layers layered and disposed between said first and second electrodes, wherein said organic semiconductor layers include an organic light-emitting layer and carrier injection and or or transport layers sandwiching the organic light-emitting layer, the organic semiconductor device further comprising a light-scattering layer layered and disposed between said organic light-emitting layer and one of said first and second electrodes placed on a side of extracting light to an outside, wherein said light-scattering layer comprises: organic materials having carrier injection and transport characteristics of transporting electrons and or or holes; and plural particles dispersed among the organic materials so that light emitted from the organic light-emitting layer is passed therethrough, wherein the organic light-emitting device further comprises a semi-transparent metal layer so that the semi-transparent metal layer and the light-scattering layer are disposed between one of carrier injection and or or transport layers and the one of said first and second electrodes placed on the side of extracting light to the outside, wherein the semi-transparent metal layer is capable of partially reflecting light and has a light transparency, the organic light-emitting device further comprising a particulate film disposed between said light-scattering layer and the one of said first and second electrodes placed on the side of extracting light to the outside wherein the particulate film contains plural particles.
