DRIVE
March 15, 2017
Provided is an organic electroluminescent element containing a flexible substrate having thereon a first electrode layer, an organic layer unit containing a light-emitting layer formed on the first electrode layer, and a second electrode layer formed on the organic layer unit, wherein the organic electroluminescent element emits light to an outside of the organic electroluminescent element with a light distribution property of the emitted light satisfying the following relationships of: 0.85 ≤ L2/L1 ≤ 1.20; and L3/L1 ≤ 0.45, provided that L1 is a front luminance, L2 is a luminance of view angle 20 degrees, and L3 is a luminance of view angle 60 degrees.
