Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . 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 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. 2 . 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 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/(m 2 ·24h). 3 . An organic electroluminescent element described in claim 2 , wherein the smooth layer contains an oxide or a nitride of silicone or niobium as a main component. 4 . An organic electroluminescent element described in claim 1 , wherein the smooth layer contains a reaction product of an inorganic silicon compound or an organic silicon compound, or niobium oxide as a main component. 5 . An organic electroluminescent element described in claim 1 , wherein a water vapor permeability of the gas barrier layer (Wg), a water vapor permeability of the light scatter layer (Ws), and a water vapor permeability of the smooth layer (Wf) satisfy the following conditional expression, Wg≦Wf<Ws. 6 . An organic electroluminescent element described in claim 1 , wherein the smooth layer has a refractive index in the range of 1.7 to 3.0. 7 . An organic electroluminescent element described in claim 1 , wherein the smooth layer contains nanoparticles having a refractive index in the range of 1.7 to 3.0. 8 . An organic electroluminescent element described in claim 1 , wherein the smooth layer has a first smooth layer and a second smooth layer in a sequential order from a side of the light-emitting unit; the first smooth layer contains an oxide or a nitride of silicone or niobium as a main component; and the second smooth layer is formed with a wet process. 9 . An organic electroluminescent element described in claim 8 , wherein the first smooth layer is formed with a dry process. 10 . An organic electroluminescent element described in claim 8 , wherein the first smooth layer is formed with a wet process. 11 . An organic electroluminescent element described in claim 8 , wherein at least one of the first smooth layer and the second smooth layer contains nanoparticles having a refractive index in the range of 1.7 to 3.0. 12 . An organic electroluminescent element described in claim 8 , wherein the first smooth layer and the second smooth layer both respectively have a refractive index in the range of 1.7 to 3.0. 13 . An organic electroluminescent element described in claim 1 , wherein the light scatter layer is patterned in a sealing region.
