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.

An optical filter is provided on the output side of light from plural kinds of cells that output light with colors different from one another. In the optical filter, the penetrable rate of at least a portion of the wavelength band of light output from the cell with the color having highest luminescent intensity is set lower than that of the wavelength band of other kinds of cells. Consequently, the reflectance rate of outer light incident to a display can be reduced. Particularly, in a room environment using artificial lighting, the reflectance rate of outer light can be reduced in the wavelength band of light with relatively high luminescent intensity. Resultingly, bright room contrast can be improved by suppressing the reflection of outer light. Since the penetrable rate of the color with the highest luminescent intensity is reduced, reduction in brightness of the display can be kept to a minimum.
