Patent ID: 8809845

Claim:
A display apparatus comprising: a first organic electroluminescent element to emit a first color; and a second organic electroluminescent element to emit a second color different from the first color, both of the organic electroluminescent elements being provided with an anode, a cathode, and a light-emitting layer disposed between the anode and the cathode, wherein a first light-emitting layer of the first organic electroluminescent element is disposed in common to the 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 side nearer to the anode than is the first light-emitting layer, and the second light-emitting layer contains a host material and a light-emitting dopant material and is configured to satisfy Relational expressions (A) and (B) described below, |HOMO D2 |<|HOMO H2 | (A) |HOMO H2 |−|HOMO D2 |>|LUMO D2 |−|LUMO H2 | (B) where LUMO H2 and HOMO H2 represent the LUMO level energy and the HOMO level energy, respectively, of the host material contained in the second light-emitting layer and LUMO D2 and HOMO D2 represent the LUMO level energy and the HOMO level energy, respectively, of the light-emitting dopant material contained in the second light-emitting layer.
