An organic EL device includes an organic EL emitter (2) that emits blue light and a blue color filter (8B) through which the light emitted from the organic EL emitter passes. The blue color filter contains a coloring material selected from the group consisting of a triarylmethane dye, a lake pigment, a copper-phthalocyanine pigment, and a mixture of a copper-phthalocyanine pigment and a dioxazine pigment. The chromaticity of the light, the light that has passed through the blue color filter after emitted from the organic EL emitter, is in the range defined by lines connecting three chromaticity coordinates (0.150, 0.060), (0.143, 0.031), and (0.130, 0.049) on the CIE chromaticity diagram.
