摘要： An organic EL element (200) emits light containing a blue component (B) and a component (θ) with a peak in 500 to 600 nm. A red converting member (360) has an excitation spectrum with a peak in 500 to 600 nm. The red converting member receives light from the organic EL element (200) and converts the blue component (B) to a red component (R). At this time, the luminance of the red component (R) is enhanced since the member (360) is strongly excited by the component (θ). As a result, the white balance of three colors is improved. Therefore a color emission device (100) can be provided where the intensity of red light is enhanced.
