Abstract
This organic EL display device is provided with: a TFT substrate; a counter substrate; an organic EL element provided on the TFT substrate; a sealing film that seals the organic EL element; a color filter layer provided on the counter substrate on a side closer to the organic EL element; and a filler layer that is filled between the sealing film and the color filter layer. This organic EL display device satisfies nM(h−1)/nMh×LM(h−1)/√(TM(h−1)+LM(h−1))≥1, nMh/ng×LMh/√(TMh+LMh)≥1, ng/nCF×Lg/√(Tg+Lg)≥1, nCF/nGL×LCF/√(TCF+LCF)≥1, or nGL/nair×LGL/√(TGL+LGL)≥1, while satisfying XEC/2+XBM/2≥Σ(TMi×tan θMi)+Tg×tan θg+TCF×tan θCF.
