摘要:
In a display apparatus including pixels, each of which has organic EL elements which emit red, green, and blue (RGB) colors and a refractive index-control layer, an electrode at a light extraction side of each organic EL element is a silver layer in contact with a charge transport layer, the refractive index-control layer is arranged on the silver layer in common with the organic EL elements which emit RGB colors, and an effective refractive index (neff) represented by the following formula is in a range of 1.4 to 2.3. neff=0.7×nu+0.3×nd In the above formula, nu indicates the refractive index of the refractive index-control layer 3, and nd indicates the refractive index of the charge transport layer 1.
