Abstract:
1. An organic EL device comprising: an organic EL emitter that emits blue light; a blue color filter through which the light emitted from the organic EL emitter passes, the blue color filter having a coloring layer including a dye as a coloring material; an adhesive layer disposed between the organic EL emitter and the blue color filter; and a transparent protective layer disposed between the blue color filter and the adhesive layer; wherein the transparent protective layer is formed on an upper surface of the coloring layer with the use of a transparent resin, and the transparent protecting layer protects the coloring layer from active components in an adhesive agent included in the adhesive layer; and wherein the chromaticity of the light that has passed through the blue color filter after being emitted from the organic EL emitter falls in the range defined by lines connecting three chromaticity coordinates (0.140, 0.080), (0.136, 0.040), and (0.118, 0.070) on the CIE chromaticity diagram.
