COLOR EMISSION DEVICE |
摘要 |
<p>An organic EL element (200) emits light containing a blue component (B) and a component (&thetas;) with a peak in 500 to 600nm. A red converting member (360) has an excitation spectrum with a peak in 500 to 600nm. 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 (0). 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. <IMAGE></p> |
