Abstract:
1. A top-emission organic electroluminescence device, comprising, in the following order: a substrate; a first electrode; an organic layer comprising a blue-emitting layer; a second electrode; and a capping layer, wherein: the capping layer comprises a material having (i) an extinction coefficient of 0.1 or less at a wavelength of 430 to 500 nm, and (ii) an amount of charge in refractive index that satisfies an expression (1): wherein, n(λ=x nm) is a refractive index at a wavelength of x nm; the organic layer further comprises a red-emitting layer and a green-emitting layer; and a blue pixel, a red pixel, and a green pixel are disposed on a common substrate, and the capping layer is provided common to the blue pixel, the red pixel, and the green pixel.
