ABSTRACT:
An electro-luminescent conversion light emitting device for use in an information communication field. The light emitting device includes a semi-transparent reflective film substrate. On the semi-transparent reflective film is formed a transparent conductive film. On the transparent conductive film is formed a light emitting layer of organic thin film on the transparent conductive film. On the light emitting layer is formed an electrode. The semi-transparent reflective film 2 transmits parts of the light emitted by the light emitting layer to the glass substrate and reflects parts of the light to the light emitting layer. The semi-transparent reflective film acts as a light resonator with the Ag-Mg metal electrode on back of the light emitting layer.
