Patent ID: 8344370

Claim:
A display apparatus comprising: pixels each of which includes: an organic El element emitting red light; an organic El element emitting green light; an organic El element emitting blue light, and a refractive index-control layer, wherein the organic EL elements each include: an anode; a cathode; and an organic compound layer provided therebetween which contains a luminous layer and a charge transport layer, wherein one of the anode and the cathode arranged at a light extraction side is a silver layer which contains silver, which has a thickness of less than 30 nm, and which is in contact with the charge transport layer, the refractive index-control layer is arranged on the silver layer in common with the organic El element emitting red light, the organic El element emitting green light, and the organic El element emitting blue light, and an effective refractive index (n eff ) represented by the following formula is in a range of 1.4 to 2.3 N eff =0.7 ×n u +0.3 ×n d where n u indicates the refractive index of the refractive index-control layer, and n d indicates the refractive index of the charge transport layer.
