PROBLEM TO BE SOLVED: To provide an organic electroluminescent device which is excellent in durability and luminous efficiency and in which deterioration in display performance due to curling of a substrate is suppressed.SOLUTION: The organic electroluminescent device has a first optical layer containing first particles and a binder, a flexible substrate, a barrier layer, a second optical layer containing second particles and a binder, a first electrode, an organic layer including an organic light-emitting layer, and a second electrode in this order. The first particles and the second particles are made of an organic material. The average particle diameter of the first particles is larger than that of the second particles. |
