A first light-emitting layer of a first organic electroluminescent element is disposed in common to a second organic electroluminescent element, a second light-emitting layer of the second organic electroluminescent element is disposed in contact with the first light-emitting layer and in the cathode side, and the first light-emitting layer contains a host material and an assist dopant material to transport holes to the second light-emitting layer.

Display apparatus and image pickup apparatus

An organic light-emitting element includes a first electrode, an organic compound layer, and a second electrode on a substrate and emits light from the second electrode side, wherein the second electrode includes a first layer and a second layer in contact with the first layer sequentially from the substrate side, the second layer is a layer comprising Ag, and the first layer is a layer comprising Ag and Cs.

Organic light-emitting element, light-emitting apparatus, image forming apparatus, display apparatus, and image pickup apparatus

An organic EL element includes a first electrode, an organic compound layer, and a second electrode on a substrate. The second electrode includes a first metal layer and a second metal layer in this order from the substrate side. The second metal layer contains Ag and has a thickness of 5.0 nm or more and 20 nm or less. The first metal layer contains Mg and Ag and has a thickness of 1.0 nm or more and 5.0 nm or less.

Organic electroluminescent element and light-emitting apparatus using the same

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 (n) represented by the following formula is in a range of 1.4 to 2.3.=0.7&#xd7;+0.3&#xd7;In the above formula, nindicates the refractive index of the refractive index-control layer, and nindicates the refractive index of the charge transport layer
