Abstract:
To provide a charge injection layer in which the refractive index is sufficiently low and unbalance in the composition of materials is less likely to occur, and a method for its production as well as an organic photoelectronic element and a method for its production. The charge injection layer contains a fluorinated polymer and a semiconductor material, and has a refractive index in the wavelength range of from 450 to 800 nm, of at most 1.60.
