Abstract:
1. An organic electroluminescent device comprising: a first substrate having a first surface; a second substrate having a second surface facing the first surface and a third surface provided opposite to the second surface, the third surface having a first concave-convex portion, the second substrate being light transmissive, the second surface including a second concave-convex portion having a height 1 μm or more 50 μm or less; a sealing portion provided between the first substrate and the second substrate; a stacked body provided in a space sealed by the first substrate and the second substrate and the sealing portion, the stacked body including: an intermediate layer provided between the second substrate and the stacked body, the intermediate layer extending between the sealing portion and the stacked body, an absolute value of a difference between a refractive index of the intermediate layer and a refractive index of the first electrode being smaller than an absolute value of a difference between a refractive index of the second substrate and a refractive index of the first electrode, a distance between the second surface and the stacked body along a direction perpendicular to the first surface being 2 μm or more 500 μm or less.
