ORGANIC ELECTROLUMINESCENCE ELEMENT |
摘要 |
A top-emission organic electroluminescence device (1) includes in order a first electrode (20), one or more organic layers (30B) including a blue-emitting layer (34B), a second electrode (40), and a capping layer (50), wherein the capping layer (50) is formed of a material that satisfies the expression "n(»=430 nm) - n(»=460 nm) > 0.08" (where, n(A=x nm) indicates a refractive index at a wavelength of x nm) and has an extinction coefficient of 0.1 or less at a wavelength of 430 to 500 nm. |
