| 摘要 | [It is an object] to provide an organic electroluminescent element having a transparent electrode, with which there is no need to produce a separate light extraction layer, [which can be produced by] a simple film formation process, and which is advantageous in terms of cost. [This is] an organic electroluminescent element in which a substrate, a first transparent electrode that is adjacent to this substrate, an organic layer including at least one organic light-emitting layer, a second transparent electrode, a low refractive-index layer with a refractive index of 1.3 or less, and a reflector layer are formed in this order, with this organic electroluminescent element being such that the aforementioned first transparent electrode contains at least one type of transparent particle with a primary particle size of 0.5 μm or more. | ||

| 主权项 | 1. An organic electroluminescent element, comprising, in this order: a substrate, a first transparent electrode that is in direct contact with the substrate, an organic layer including at least one organic light-emitting layer, a second transparent electrode, a low refractive-index layer with a refractive index of 1.3 or less, and a reflector layer, wherein said first transparent electrode contains at least one type of transparent particle with a primary particle size of 0.5 μm or more, wherein said first transparent electrode is composed of two layers: a first layer containing at least one type of transparent particle with a primary particle size of 0.5 μm or more and a second layer that does not contain transparent particles with a primary particle size of 0.5 μm or more but does contain particles with a primary particle size of 100 nm or less, and wherein the absolute value of the difference between the refractive index of the constituent components of the second layer and the refractive index of the constituent components of the first layer, not including the at least one type of transparent particle with a primary particle size of 0.5 μm or more, is 0.02 or less. | ||
