Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electroluminescent display device improved in a straight advancing property of light in a light transmitting transparent substrate and provided with excellent luminance and color control. SOLUTION: This organic EL display device 1 is provided with a transparent electrode 3 formed on the transparent substrate 2 for injecting one conductor type carrier, an active layer formed of an organic material, and an electrode 5 for injecting the other conductor type carrier. In the transparent substrate 2, a refractive index of a first area 2a facing the light emission face of the active layer 4 is higher than that of another second area 2b. COPYRIGHT: (C)2003,JPO
