Abstract
In a self light emitting display device of the present invention, a first electrode 3 for example formed of a thin film of ITO is formed in a striped pattern on a glass substrate 2, and a film of a light emission functional layer 6 is formed thereon. A metallic second electrode 7 is formed on the light emission functional layer 6, and a light transmitting sealing member 8 for example formed of a glass material is superimposed on the second electrode 7. Apertures 7a for allowing image light from the light emission functional layer 6 to pass through are formed on a part of the second electrode 7, a first light emitting area L1 is formed in the glass substrate 2 side, and a second light emitting area L2 is formed in the sealing member 8 side. As a result, display images can be visually recognized on both front and rear surfaces.
