ABSTRACT:
An organic EL element (100) emits light containing blue, green and red components. A blue color filter (420) transmits only the blue component. A green-converting member (340) converts the blue component to the green component, and a green color filter (440) transmits only the green component. A red-converting member (360) converts the blue component and the green component to the red component, and a red color filter (460) transmits only the red component. Since the respective color filters (420, 440and460) block unnecessary color components, the reproducibility of the respective color is improved. Since the luminescence of the organic EL element (100) contains the green component and the red component besides the blue component, white balance becomes good. It is therefore possible to provide a color luminous device from which improved light rays in the three primary colors can be emitted.
