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.
Claims10
An organic EL display device in which pixels of plural colors are arranged in a display region, each of the pixels having a light emitting unit of organic electroluminescence and emitting light from the light emitting unit, the light having a spectrum and a wavelength band which correspond to one of the plural colors, the wavelength band being different from a wavelength band corresponding to another of the plural colors,
- the organic EL display device comprising:
- an absorption filter that absorbs a light in a given absorption spectrum uniform in the display region,
- wherein the absorption spectrum has a negative correlation with an outgoing spectrum obtained by synthesizing spectrums which are different from each other, and
- each of the spectrums corresponds to each of the plural colors.
