Abstract: An organic EL display device ensures brightness and improves a contrast ratio by a reduction in external light reflection. The organic EL display device includes a wavelength selective absorption filter that absorbs a light in a given absorption spectrum uniform in a display region. An absorption spectrum has a negative correlation with an outgoing spectrum in which respective spectrums of R pixels, G pixels, and B pixels are synthesized together.
