PROBLEM TO BE SOLVED: To provide a durable film containing a coumarin compound having a specific structure, a durable color conversion filter, and a multi color light-emitting device. SOLUTION: The film contains a coumarin compound having a specific structure, and the color conversion layer contains the coumarin compound, and a matrix comprising a straight silicone polymer or a resin-modified silicone polymer. The color conversion layer absorbs light, having a specific wave length to emit light containing a wave length different from that of the absorbed light, and the color conversion filter includes a transparent substrate, a color conversion layer or a plurality of color conversion layers, having different wave length distributions respectively, and at least one of the color conversion layer contains the color conversion layers having the characteristics described. By having a complimentary color filter integrated with the color conversion filter and a protective layer, the multi-color light-emitting device is formed, by assembling the filters and an organic light-emitting body that emits light by applying electric field.
