Abstract
A display device includes an organic EL element layer, a liquid crystal element layer disposed on top of the organic EL element layer, and a polarizing plate disposed at a side of the liquid crystal element layer that faces an observer. The liquid crystal element layer includes two transparent substrates and a liquid crystal layer disposed between the two transparent substrates. The liquid crystal element layer is configured to be able to, by applying a voltage to the liquid crystal layer, cause a substantially quarter-wavelength retardation in light passing through the liquid crystal layer.
