DISPERSION TYPE ELECTROLUMINESCENCE ELEMENT

摘要

A white-light-emitting dispersion type EL element excellent in color rendering property (especially, red). A dispersion type electroluminescence element comprising a transparent electrode, a rea-surface electrode, and a light emitting particle layer held between the both electrodes, wherein a curve I(?) obtained by normalizing spectrum when the element emits light is set to satisfy, in a wavelength region of 410nm through 650nm, g(?)= I(?)= f(?). [Expression 1] g(?)=0.9exp(-ln(2)((?-490)/25))<sup
