In order to provide an organic electroluminescent display device which does not exhibit redness in reflected external light, and exhibits little fluctuation in the hue of a black image as a result of changes in environmental temperature and differences in the light emitting state, the organic electroluminescent display device according to the present invention comprises, in order from the viewing side, a protective film, a polarizer, a λ/4 phase difference film, and an organic electroluminescent element, and is characterized in that the λ/4 phase difference film satisfies formulas (1) and (2) below. n Ro (450)< Ro (550)< Ro (650) Formula (1)n n 0.90<photoelastic coefficient ratio(450/650)value<1.20 Formula (2) |
