Abstract
Provided is an organic electroluminescent element including a film substrate having thereon: at least one gas barrier layer, a light scatter layer, at least one smooth layer, and a light-emitting unit containing an organic functional layer interposed between a pair of electrodes, laminated in this order, wherein the light scatter layer contains a binder and light scatter particles having an average particle size of 0.2 μm or more to less than 1 μm; and the smooth layer contains an oxide or a nitride of silicone or niobium as a main component.

An organic electroluminescent element comprising a film substrate having thereon:
- at least one gas barrier layer, a light scatter layer, at least one smooth layer, and a light-emitting unit containing an organic functional layer interposed between a pair of electrodes, laminated in this order,
- wherein the at least one gas barrier layer is in direct contact with the film substrate, and the at least one gas barrier layer contains silicon, oxygen, and carbon and has a carbon distribution curve in which an absolute value of a difference between a maximum value and a minimum value of a carbon atomic percentage is 3 at % or more,
- wherein the light scatter layer contains a binder and light scatter particles having an average particle size of 0.2 μm or more to less than 1 μm;
- and
- the smooth layer contains an oxide or a nitride of silicone or niobium as a main component.
An organic electroluminescent element comprising a film substrate having thereon:
- a first gas barrier layer, a second gas barrier layer, a light scatter layer, at least one smooth layer, and a light-emitting unit containing an organic functional layer interposed between a pair of electrodes, laminated in this order,
- wherein the first gas barrier layer is in direct contact with the film substrate, and the first gas barrier layer contains silicon, oxygen, and carbon and has a carbon distribution curve in which an absolute value of a difference between a maximum value and a minimum value of a carbon atomic percentage is 3 at % or more,
- wherein the light scatter layer contains a binder and light scatter particles having an average particle size of 0.2 μm or more to less than 1 μm;
- and
- the smooth layer has a water vapor permeability of less than 0.1 g/(m2·24 h).
