PROBLEM TO BE SOLVED: To provide a color film for an organic EL device that has an improved blue color purity and small reduction of a luminance (PL intensity) and is superior in haze, average transmittance of visible light, heat resistance, and moisture and heat resistance when the film is used in the organic EL device, in particular a blue organic EL device. SOLUTION: The color film for an organic EL device is characterized in that the film has an adhesive layer (ii) on a transparent base film (i), and the adhesive layer (ii) contains: at least one kind of pigment of 0.05-1.50 pts.mass selected from cyanine-based pigment (B), azaporphyrin-based pigment (C) and a rhodamine-based pigment (D), which have maximum absorption in wavelengths of 510-610 nm; and isocyanate-based curing material (E) of 0.02-1.00 pts.mass, with (meta)acrylic acid ester copolymer (A) of 100 pts.mass, whose mass average molecular weight is 400,000 to 2,500,000.
