Abstract
An organic electroluminescent display includes a pair of substrates; an organic electroluminescent device between the pair of substrates, including: a pair of electrodes of an anode and a cathode, and a light-emitting layer between the pair of electrodes; and a light scattering film on a substrate on the viewing side of the pair of substrates, including: a transparent substrate film, and a light scattering layer which contains a light transmitting resin and a light scattering particle having a particle size of front more than 1.2 μm to 3.0 μm, wherein a ratio of (np/nb) is from 0.80 to 0.95 or from 1.05 to 1.35, taking a refractive index of the light scattering particle and the light transmitting resin as np and nb, respectively.
