A display device includes: a third electrode provided on a side of the second electrode opposite to the light-emitting layer; and an efficiency improving layer improving an efficiency of light extraction from the light-emitting layer, and the efficiency improving layer being provided between the second and third electrodes. The first and third electrodes are each in a laminated structure including a first layer being transmissive, and a second layer being transmissive and having a refractive index higher than a refractive index of the first layer.
