Abstract: A display device has layers that are laminated. The layers includes: a display layer that has a display surface for displaying an image composed of unit pixels; a pixel electrode layer arranged to correspond to each of unit pixels; a light emitting element layer laminated on the pixel electrode layer and arranged to emit light with its luminance controlled by a current; a common electrode layer provided so as to be laminated on the light emitting element layer; and a sealing layer that seals a light emitting element. The layers include at least two layers for holding the light emitting element layer therebetween and having a microcavity structure. Diffraction gratings are formed on an interface between a first grating layer and a first organic layer and on an interface between a second grating layer and a second organic layer respectively, and consequently a viewing angle is widened.
