Abstract
Disclosed is an organic electroluminescent display panel and a fabrication method thereof. The organic electroluminescent display panel includes: a first base substrate and a second base substrate, a plurality of first organic electroluminescent units disposed at intervals from each other on a side of the first base substrate facing the second base substrate; and a plurality of second organic electroluminescent units disposed at intervals from each other on a side of the second base substrate facing the first base substrate. The plurality of first organic electroluminescent units is spaced apart from the plurality of second organic electroluminescent units in a direction perpendicular to an extending plane of the first base substrate. An orthographic projection of each first organic electroluminescent unit on the second base substrate at least partially overlaps with a corresponding second organic electroluminescent unit.
