Abstract
Display devices and electronic devices are disclosed. In one example, a display device includes lower electrodes arrayed in a matrix on a substrate; partition walls between adjacent ones of the lower electrodes; an organic layer formed by stacking material layers on an entire surface including upper surfaces of the lower electrodes and upper surfaces of the partition walls; and an upper electrode formed on an entire surface including an upper surface of the organic layer. In pixels with a light emitting unit in which the lower electrodes, the organic layer, and the upper electrode are stacked, light in a predetermined band is extracted to the outside by a resonator structure formed between the lower electrode and the upper electrode, and light in a band different from the predetermined band is extracted to the outside by total reflection at an interface between the organic layer and the partition wall.
