Abstract:
An organic EL device includes a metal layer which is provided with a nano-order-sized unevenness on one surface and plural organic layers which include a light emitting layer provided on the one surface side of the metal layer, and a height of each unevenness at respective interfaces in the organic layer is made smaller than an unevenness provided on the metal layer. According to the above configuration, the unevenness on one surface of the metal layer changes a surface plasmon to a propagation light and a light loss can be suppressed, and moreover, each unevenness of respective interfaces of the respective organic layers is made smaller than the unevenness on the surface of the metal layer, so that a short circuit inside the device can be suppressed.
