ORGANIC LUMINESCENT ELEMENT AND ITS SUBSTRATE.

摘要

An electro-optic transducing element used in the field of information communication. This element has a semi-transparent reflecting layer (2) on a transparent substrate (1), a transparent conductive layer (3) on the semi-transparent reflection layer (2), a luminescent layer (5) of an organic thin film on the transparent conductive layer (3), and electrodes (7) formed on the layer (5). The semi-transparent reflective layer (2) transmits a part of the light emitted by the luminescent layer (5) toward the transparent substrate (1), and reflects a part of the light toward the luminescent layer (5). The semi-transparent reflection layer (2) forms resonators together with the electrodes (7).
