ORGANIC ELECTROLUMINESCENCE DEVICE

摘要

An organic EL device (1) is provided with a metal layer (2) whereon projections and recessions (2') on a nano order of magnitude are provided on one face, and a plurality of organic layers (3) that include a light emission layer (31) provided on one side of the metal layer (2). The height of the projections and recessions at each boundary face of the organic layers (3) is configured to be smaller than the projections and recessions (2') disposed on the metal layer (2). This configuration enables, due to the projections and recessions (2') of one of the faces of the metal layer (2), a reduction of the light loss that occurs in the conversion of surface plasmon to propagation light; and by making the projections and recessions of each boundary face of each organic layer (3) smaller than the projections and recessions on the face of the metal layer (2), shorts within the device can be suppressed.
